Electronic mail advertising has developed from batch-and-blast campaigns to stylish, data-driven stories. System finding out algorithms analyze patterns, are expecting conduct, and personalize e-mail advertising at scale. No longer each ML utility delivers effects, and groups frequently in finding it arduous to differentiate between hype and impactful use instances.

This information cuts in the course of the noise. You‘ll be told efficient gadget finding out methods, get ready your records, and put into effect ML options in stages, whether or not you’re a solo marketer or main a staff. We will additionally speak about commonplace pitfalls that waste time and funds and supply sensible steps to measure ROI and handle model integrity.

In contrast to rules-based automation (if touch X does Y, ship e-mail Z), ML fashions in finding patterns people can not spot manually and adapt as new records arrives.

It is distinct from normal AI in two techniques: ML is narrowly concerned about prediction and trend popularity, whilst AI encompasses broader functions similar to herbal language working out and era. And in contrast to static segmentation guidelines you write as soon as, ML fashions regularly refine their predictions as they ingest extra engagement alerts.

The place System Finding out Works

• Personalization at scale: Choosing the right content material, product, or be offering for every recipient in keeping with their conduct and profile.
• Ship-time optimization: Predicting when every touch is perhaps to interact.
• Predictive scoring: Figuring out which leads are able to shop for or susceptible to churning.
• Replica and topic line trying out: Accelerating multivariate assessments and surfacing profitable patterns sooner.
• Dynamic suggestions: Matching merchandise or content material to particular person personal tastes.

The place System Finding out Does not Paintings

• When your records is messy or incomplete: Rubbish in, rubbish out — ML amplifies dangerous records.
• As an alternative choice to technique: Fashions optimize towards the metrics you select; in case you are measuring the improper factor, ML gets you there sooner.
• With out enough quantity: Maximum fashions want masses or hundreds of examples consistent with section to be told reliably.
• For extremely ingenious, brand-sensitive reproduction: ML can counsel and take a look at, however it can not substitute human judgment on tone and model voice.
• While you skip dimension: For those who don‘t examine ML efficiency on your baseline, you gained’t know if it is running.

System finding out shines if you have blank, unified records, transparent good fortune metrics, and adequate quantity to coach fashions. It falls quick when records high quality is deficient, targets are obscure, or you are expecting it to interchange strategic considering.

Steps to Take Prior to You Transfer ML on for Your Electronic mail Advertising Campaigns

Maximum gadget finding out screw ups happen ahead of the primary type is administered. Deficient records high quality, fragmented touch data, and lacking consent flags will sabotage even the neatest algorithms. Prior to you permit ML options, put money into those foundational steps.

1. Unify contacts, occasions, and lifecycle levels.

System finding out fashions want a unmarried supply of reality. In case your touch records lives in a couple of techniques — e-mail platform, CRM, ecommerce backend, beef up table — fashions can not see the whole image. A touch who deserted a cart, opened 3 emails, and referred to as beef up final week seems like 3 separate other people except you unify the ones data.

Get started via consolidating contacts into one device that tracks identification, lifecycle degree, and behavioral occasions on a shared timeline. Map key actions — shape submissions, purchases, beef up tickets, content material downloads — to lifecycle levels like Subscriber, Lead, Advertising Certified Lead, Alternative, and Buyer. This mapping provides ML fashions the context they want to are expecting subsequent movements.

Identification answer issues right here: if [email protected] and [email protected] are the similar particular person, merge them. If a touch switches from a non-public to a piece e-mail, hyperlink the ones identities. The extra entire every touch file, the easier your fashions carry out.

HubSpot Sensible CRM robotically unifies contacts, tracks engagement throughout channels, and maintains a unmarried timeline for each interplay — giving your ML fashions the blank, hooked up records they want to personalize successfully.

2. Automate records high quality and consent control.

Prior to you educate fashions, blank your records. Deduplicate contacts, standardize box formatting (lowercase emails, constant nation names, formatted telephone numbers), and tag consent standing for each file. If 15% of your contacts have reproduction entries or lacking lifecycle levels, your segmentation and scoring fashions will misfire.

Arrange automatic workflows to:

• Deduplicate contacts on e-mail cope with and merge data with matching identifiers
• Standardize box values the use of look up tables or validation guidelines (e.g., map “US,” “USA,” and “United States” to at least one cost)
• Enrich lacking records via appending firmographic or demographic attributes from relied on resources
• Flag and quarantine dangerous data that fail validation assessments till a human opinions them
• Monitor consent personal tastes on the box point — e-mail, SMS, third-party sharing — and appreciate opt-outs in genuine time

Handbook cleanup is a brief repair. Automate high quality assessments so new data arrive blank and present data keep correct as they age. Knowledge high quality automation in Operations Hub reduces mistakes, prevents duplicates, and assists in keeping consent flags up-to-the-minute, making sure your ML fashions educate on dependable alerts relatively than noise.

3. Audit your tournament monitoring and attribution.

ML fashions be told from conduct, now not simply static attributes. If you are now not monitoring key occasions—e-mail opens, hyperlink clicks, web page perspectives, purchases, downloads, demo requests—your fashions will lack the alerts they want to are expecting engagement or conversion.

Audit your tournament schema: Are you shooting the occasions that subject to your enterprise? Are you able to tie every tournament again to a particular touch? Do occasions elevate adequate context (product considered, buck cost, content material kind) to tell personalization?

Repair gaps via instrumenting your web page, e-mail platform, and product with constant tournament monitoring. Use UTM parameters and monitoring pixels to characteristic conversions again to express campaigns and contacts. The richer your tournament records, the sharper your predictions.

4. Set baseline metrics ahead of you turn the transfer.

You’ll be able to‘t measure ML’s affect and not using a baseline. Prior to you permit any gadget finding out characteristic, file your present efficiency:

• Open price and click-through price via section and crusade kind
• Conversion price from e-mail on your function motion (buy, demo request, signup)
• Earnings consistent with e-mail and buyer lifetime cost via acquisition supply
• Unsubscribe price and junk mail grievance price

Run a holdout take a look at if imaginable: observe ML to a remedy workforce and examine effects to a keep an eye on workforce receiving your usual method. This isolates ML’s affect from seasonality, exterior campaigns, or adjustments on your target market.

Monitor those metrics over no less than two to 3 crusade cycles post-launch so you’ll distinguish sign from noise. Fast wins like send-time optimization would possibly display ends up in weeks; longer-term good points like predictive scoring and churn prevention compound over months.

Confirmed Electronic mail Advertising ML Use Circumstances You Can Deploy Now

No longer all gadget finding out programs ship equivalent cost. Those use instances have the most powerful observe data throughout industries and staff sizes. For every, we will provide an explanation for what it does, when it really works very best, and the commonest mistake to keep away from.

1. AI Electronic mail Personalization and Dynamic Content material

What it does: System finding out selects content material blocks, photographs, product suggestions, or calls-to-action for every recipient in keeping with their profile and behaviour. As a substitute of constructing separate campaigns for each section, you design one template with a couple of variants, and the type chooses the most productive aggregate consistent with touch.

When it really works very best: Prime-volume campaigns with various audiences — newsletters, onboarding sequences, promotional emails. You wish to have adequate historic engagement records (opens, clicks, conversions) for the type to be told which content material resonates with which profiles.

Commonplace mistake: Personalizing for the sake of personalization. Simply since you can change in a touch‘s first title or corporate doesn’t imply it improves results. Personalize components that vary decision-making — provides, product suggestions, social evidence — now not beauty main points. Take a look at personalised vs. static variations to verify elevate.

Professional tip: For sooner content material introduction, use HubSpot’s AI e-mail author to generate personalised e-mail reproduction at scale, or faucet the AI e-mail reproduction generator to create campaign-specific messaging that adapts on your target market segments.

2. Ship Time Optimization via Recipient

What it does: As a substitute of sending each e-mail at 10 a.m. Tuesday, a send-time optimization type predicts the hour every touch is perhaps to open and have interaction, then schedules supply accordingly. The type learns from every touch’s historic open patterns—time of day, day of week, tool kind—and adjusts over the years.

When it really works very best: Campaigns the place timing flexibility does not harm your message (newsletters, nurture sequences, promotional bulletins). Much less helpful for time-sensitive emails like webinar reminders or flash gross sales the place everybody must obtain the message inside a decent window.

Commonplace mistake: Assuming optimum ship time on my own will change into effects. Ship-time optimization in most cases lifts open charges via 5–15%, now not 100%. It is a marginal acquire that compounds over many sends. Pair it with robust topic strains, related content material, and wholesome checklist hygiene for optimum affect.

HubSpot Advertising Hub e-mail advertising comprises send-time optimization that analyzes engagement historical past and robotically schedules emails when every touch is perhaps to open.

3. Predictive Lead Scoring and Churn Chance

What it does: Predictive scoring fashions analyze masses of attributes—activity name, corporate dimension, web page visits, e-mail engagement, content material downloads—to assign every touch a ranking representing their probability to transform or churn. Prime ratings pass to gross sales or obtain extra competitive nurture; low ratings get lighter-touch campaigns or re-engagement sequences.

When it really works very best: B2B firms with outlined gross sales funnels and adequate closed offers to coach the type (in most cases 200+ closed-won and closed-lost alternatives). Additionally efficient in B2C subscription companies for figuring out churn possibility ahead of cancellation.

Commonplace mistake: Trusting the ranking with out validating it. Fashions will also be biased via out of date assumptions (e.g., overweighting activity titles that have been as soon as robust alerts however now not correlate with conversion). Continuously examine predicted ratings to exact results and retrain when accuracy drifts.

Predictive lead scoring in HubSpot builds and updates scoring fashions robotically the use of your closed offers and make contact with records. It surfaces the contacts perhaps to transform, so your staff focuses effort the place it issues maximum.

4. Topic Line and Replica Optimization

What it does: ML fashions analyze hundreds of previous topic strains and e-mail our bodies to spot patterns that pressure opens and clicks. Some platforms generate topic line variants and preview textual content, then run multivariate assessments sooner than guide A/B trying out. Others counsel enhancements in keeping with high-performing language patterns.

When it really works very best: Prime-send-volume techniques the place you’ll take a look at a couple of variants consistent with crusade and be told temporarily. Much less efficient in case your checklist is small (below 5,000 contacts) otherwise you ship occasionally, as a result of you will not generate adequate records to differentiate sign from noise.

Commonplace mistake: Letting the type write the whole lot. ML can boost up trying out and floor profitable patterns, however it does not perceive your model voice or strategic positioning. Use AI-generated reproduction as a kick off point, then edit for tone, compliance, and model consistency.

Generate topic strains for advertising emails with HubSpot AI to temporarily create a couple of variants for trying out, and generate preview textual content for advertising emails to finish the optimization. For broader crusade beef up, the Breeze AI Suite provides AI-assisted reproduction and trying out workflows that combine throughout your advertising hub.

5. Dynamic Suggestions for Ecommerce and B2B

What it does: Advice engines are expecting which merchandise, content material items, or sources every touch will in finding maximum related in keeping with their surfing historical past, previous purchases, and the conduct of identical customers. In ecommerce, this may well be “shoppers who purchased X additionally purchased Y.” In B2B, it might be “contacts who downloaded this guide additionally attended this webinar.”

When it really works very best: Catalogs with no less than 20–30 pieces and adequate transaction or engagement quantity to spot patterns. Works particularly properly in post-purchase emails, browse abandonment campaigns, and content material nurture sequences.

Commonplace mistake: Recommending merchandise the touch already owns or content material they have already fed on. Exclude bought pieces and considered content material from suggestions, and prioritize complementary or next-step provides as a substitute.

HubSpot Advertising Hub e-mail advertising lets you construct dynamic advice blocks that pull out of your product catalog or content material library and personalize in keeping with touch conduct.

Professional tip: For extra complex ways, discover how AI improves e-mail conversions and localize AI-generated emails for international audiences.

Measuring the ROI of System Finding out for Electronic mail Advertising

Self-importance metrics like open charges and click-through charges let you know what came about, now not whether or not it mattered. To turn out ML’s cost, tie e-mail efficiency to industry results to metrics like income, pipeline, buyer retention, and lifelong cost.

Shift from task metrics to industry results.

Open and click on charges are helpful diagnostics, however they‘re now not targets. A 30% open price approach not anything if the ones opens don’t pressure purchases, signups, or certified leads. Reframe your dimension round results:

• Earnings consistent with e-mail: General attributed income divided via emails despatched
• Conversion price: Proportion of recipients who entire your function motion (buy, demo request, obtain)
• Buyer acquisition price (CAC): Price to procure a buyer by means of e-mail vs. different channels
• Buyer lifetime cost (CLV): Lengthy-term cost of consumers obtained via e-mail campaigns

Examine ML-driven campaigns on your baseline on those metrics. If send-time optimization lifts income consistent with e-mail via 12%, that is a transparent win even supposing open price most effective progressed via 6%.

Characteristic income and pipeline to e-mail touches.

System finding out personalization and proposals affect purchasing choices throughout a couple of touchpoints. To measure their affect appropriately, put into effect multi-touch attribution that credit e-mail along different channels.

Use first-touch, last-touch, and linear attribution fashions to know the way e-mail contributes to the client adventure. As an example, if a touch receives a customized product advice e-mail, clicks via, browses however does not purchase, then converts after a retargeting advert, e-mail merits partial credit score.

HubSpot Sensible CRM tracks each interplay on a unified timeline and attributes income to the campaigns, emails, and touchpoints that influenced every deal—so you’ll see which ML-driven emails in truth pressure pipeline and closed income, now not simply clicks.

Run holdout assessments to isolate ML affect.

The cleanest solution to measure ML’s ROI is a holdout experiment: break up your target market into remedy (ML-enabled) and keep an eye on (usual method) teams, then examine efficiency over the years. This isolates ML’s affect from seasonality, exterior campaigns, or target market shifts.

As an example, permit predictive lead scoring for 70% of your database and proceed guide scoring for the opposite 30%. After 3 months, examine conversion charges, gross sales cycle duration, and deal dimension between the 2 teams. If the ML workforce converts 18% sooner with 10% upper deal values, you have confirmed ROI.

Run holdouts for 4–8 weeks minimal to clean out weekly volatility. Rotate contacts between teams periodically to verify equity and keep away from long-term bias.

Monitor potency good points and price financial savings.

ROI isn‘t simply income — it’s additionally time stored and prices have shyed away from. System finding out reduces guide paintings, hurries up trying out cycles, and improves focused on accuracy, all of which translate to cheaper price consistent with acquisition and better staff productiveness.

Measure:

• Hours stored every week on guide segmentation, checklist pulls, and A/B take a look at setup
• Price consistent with lead and price consistent with acquisition ahead of and after ML adoption
• Marketing campaign release pace: What number of campaigns your staff can execute monthly with ML vs. with out
• Error charges: Relief in misfires like sending the improper be offering to the improper section

In case your staff launches 40% extra campaigns consistent with quarter with the similar headcount, or reduces price consistent with lead via 22%, the ones potency good points compound over the years.

Observe accidental penalties.

System finding out optimizes towards the targets you put, however it could actually additionally produce accidental unwanted effects. Observe:

• Unsubscribe and junk mail grievance charges: If ML will increase e-mail frequency or personalization misfires, recipients would possibly decide out
• Emblem consistency: Make certain AI-generated reproduction aligns along with your voice and values
• Bias and equity: Take a look at whether or not sure segments (via geography, activity name, or demographic) are systematically under- or over-targeted

Arrange dashboards that observe each sure metrics (income, conversion) and detrimental signs (unsubscribes, lawsuits, low engagement) so that you catch issues early.

Examine ML efficiency to benchmarks.

Context issues. A 25% open price may well be superb in monetary services and products and mediocre in ecommerce. Examine your ML-driven effects to:

• Your historic baseline: Are you bettering vs. your pre-ML efficiency?
• Business benchmarks: How do your metrics stack up towards identical firms on your sector?
• Inner targets: Are you hitting the goals you put right through making plans?

Do not chase trade averages—chase growth over your personal baseline and alignment with your enterprise targets.

An ML Rollout Plan for Each Staff Dimension

You don‘t want endeavor sources first of all gadget finding out. The hot button is phasing in use instances that fit your staff’s capability, records adulthood, and technical sophistication. Right here‘s an instance of roll out ML in e-mail advertising whether or not you’re a staff of 1 or 100.

Construct a library of high-performing patterns (questions, urgency words, personalization tokens) to tell long term campaigns.

Segment 3 – Governance (Month 5+)

Identify a bi-weekly ML assessment assembly with crusade managers, advertising ops, and an information level particular person. Evaluation type accuracy, efficiency tendencies, and any anomalies (unexpected drops in engagement, surprising section conduct).

Create a model voice tick list for AI-generated reproduction: Does it fit our tone? Does it keep away from jargon? Does it align with our positioning? Require tick list sign-off ahead of primary sends.

Arrange A/B assessments with holdouts for brand new ML options ahead of complete rollout. Take a look at on 20% of your target market, validate effects, then scale to everybody.

Commonplace Pitfalls and Find out how to Keep away from Them

Even well-resourced groups make predictable errors when deploying gadget finding out in e-mail advertising. Listed below are the commonest pitfalls and one-line fixes for every.

Unhealthy Knowledge In, Unhealthy Predictions Out

• The issue: Fashions educated on incomplete, duplicated, or faulty touch data make deficient predictions. A scoring type that learns from out of date activity titles or merged reproduction contacts will misfire.
• The repair: Audit and blank your records ahead of you permit ML options. Deduplicate contacts, standardize fields, and validate consent flags. Make records high quality a continuing procedure, now not a one-time challenge.

Over-automation Erodes Emblem Voice

• The issue: Letting AI generate each topic line and e-mail frame with out assessment results in generic, off-brand messaging. Your emails begin to sound like everybody else’s.
• The repair: Use AI-generated reproduction as a draft, now not a last product. Require human assessment and modifying for tone, compliance, and strategic alignment. Construct model voice tips into your approval procedure.

Ignoring the Regulate Staff

• The issue: Turning on ML options and not using a baseline or holdout take a look at makes it not possible to turn out ROI. You’ll be able to’t inform if efficiency progressed as a result of ML or as a result of seasonality, product adjustments, or exterior elements.
• The repair: Run A/B assessments with remedy and keep an eye on teams for each primary ML characteristic. Measure efficiency over no less than two to 3 cycles ahead of mentioning good fortune.

Chasing Self-importance Metrics As a substitute of Results

• The issue: Celebrating a 20% open price elevate with out checking whether or not the ones opens transformed to income, signups, or pipeline. Prime engagement that does not pressure industry results wastes funds.
• The repair: Tie e-mail efficiency to income, conversion price, buyer lifetime cost, and price consistent with acquisition. Optimize for results, now not task.

Spamming “Winners” Till They Prevent Running

• The issue: As soon as a topic line trend or content material variant wins an A/B take a look at, groups overuse it till recipients turn into unaware of it. What labored in January flops via March.
• The repair: Rotate profitable patterns and retire them after 4–6 sends. Incessantly take a look at new variants and refresh ingenious to keep away from target market fatigue.

Skipping Size and Iteration

• The issue: Launching ML options and assuming they are going to paintings without end. Fashions glide as target market conduct adjustments, records high quality degrades, or industry targets shift.
• The repair: Evaluation type efficiency per 30 days. Monitor accuracy, engagement tendencies, and accidental penalties like emerging unsubscribe charges. Retrain fashions quarterly or when efficiency drops.

Regularly Requested Questions on System Finding out in Electronic mail Advertising

Do we want an information scientist to begin?

No, you don‘t want a records scientist to begin if you happen to use platforms with embedded gadget finding out. Gear like HubSpot’s predictive lead scoring, send-time optimization, and AI-assisted reproduction era care for type coaching, tuning, and deployment robotically. You do not write code or song hyperparameters; you configure settings, assessment effects, and alter in keeping with efficiency.

That stated, deeper experience is helping when you need to:

• Construct customized fashions for distinctive use instances now not lined via platform options
• Combine exterior records resources (third-party intent alerts, offline buy records) into your scoring fashions
• Run complex experimentation like multi-armed bandits or causal inference assessments

Get started with out-of-the-box ML options. Usher in an information scientist or ML engineer most effective while you’ve exhausted platform functions and feature a particular, high-value use case that calls for customized modeling.

How blank does our records want to be?

Cleaner is healthier, however you don’t want perfection. Purpose for those pragmatic thresholds ahead of you release ML options:

• Deduplication: Not up to 5% of contacts will have to be duplicates in keeping with e-mail cope with or distinctive identifier
• Identification answer: If contacts use a couple of emails or units, hyperlink the ones identities so every particular person has one unified file
• Lifecycle levels: A minimum of 80% of contacts will have to be tagged with a transparent degree (Subscriber, Lead, MQL, Alternative, Buyer)
• Key occasions tracked: You will have to seize the 5–10 behaviors that subject maximum (e-mail opens, hyperlink clicks, purchases, demo requests, web page perspectives)
• Consent flags: Each touch will have to have an up-to-date opt-in or opt-out standing for e-mail, SMS, and third-party sharing

How temporarily are we able to be expecting to peer effects from gadget finding out in e-mail?

It is dependent upon the use case and your ship quantity:

Fast wins (2–4 weeks):

• Ship-time optimization frequently presentations measurable open price elevate inside two to 3 sends, so long as you’ve gotten historic engagement records for every touch
• AI-assisted topic line trying out hurries up finding out vs. guide A/B assessments, surfacing winners in 3–5 sends as a substitute of 10+

Medium-term good points (1–3 months):

• Dynamic personalization and predictive lead scoring require a couple of crusade cycles to amass adequate efficiency records. Be expecting to peer conversion price enhancements after 6–10 sends to scored or personalised segments
• Churn prediction fashions want no less than one churn cycle (per 30 days or quarterly, relying on your enterprise) to validate accuracy

Lengthy-term compounding (3–6 months):

• Advice engines enhance as they ingest extra behavioral records. Early suggestions is also generic; after 3 months of engagement records, they turn into extremely personalised
• Fashion retraining and optimization delivers compounding good points over the years. A scoring type that is 70% correct in month one may succeed in 85% accuracy via month six as you refine options and retrain on extra closed offers

Set sensible expectancies with stakeholders: ML isn‘t magic. It’s a compounding benefit that improves with quantity, iteration, and information high quality over the years.

1. Launching ML and not using a baseline or keep an eye on workforce. For those who don‘t know what efficiency gave the impression of ahead of ML, you’ll’t turn out ROI. At all times run A/B assessments or observe pre- and post-ML metrics.
2. Trusting AI-generated reproduction with out human assessment. Fashions frequently lack an working out of your model voice, criminal necessities, and strategic positioning. Require human approval ahead of each ship.
3. Ignoring records high quality. Rubbish records produces rubbish predictions. Put money into deduplication, consent control, and tournament monitoring ahead of you permit ML options.
4. Optimizing for opens and clicks as a substitute of income. Prime engagement that doesn‘t convert is vainness. Measure ML’s affect on industry results—purchases, pipeline, retention—now not simply e-mail metrics.
5. Over-relying on one profitable trend. As soon as a topic line system or content material variant wins, groups frequently overuse it, inflicting recipients to song it out. Rotate winners and regularly take a look at contemporary ingenious.

How will have to we group of workers and govern ML in e-mail advertising?

Roles:

• ML proprietor (advertising ops or e-mail supervisor): Configures ML options, screens efficiency, and escalates problems. Owns the weekly or bi-weekly assessment cadence.
• Content material reviewer (crusade supervisor or copywriter): Approves AI-generated reproduction for tone, model, and compliance ahead of sends.

• Government sponsor (CMO or advertising director): Units ML targets, approves funds and sources, and opinions ROI quarterly.

Rituals:

• Weekly efficiency examine (quarter-hour): Evaluation open charges, conversion charges, unsubscribe charges, and any anomalies — flag underperforming fashions or campaigns for deeper research.
• Bi-weekly crusade assessment (half-hour): Stroll via upcoming campaigns that use ML options. Approve AI-generated reproduction, assessment personalization good judgment, and make sure dimension plans.
• Per thirty days governance assembly (60 mins): Evaluation type accuracy, speak about bias or equity issues, approve new use instances, and replace coaching records or options as wanted.
• Quarterly technique consultation (2 hours): Examine ML ROI to targets, prioritize next-phase use instances, and alter staffing or funds in keeping with effects.

Guardrails:

• Approval gates: Require human sign-off for AI-generated reproduction in high-stakes campaigns (product launches, government comms, regulated industries).
• Rollback procedures: If a type degrades efficiency, revert to the prior model inside 24–48 hours. Behavior a autopsy and attach the problem ahead of re-launching.
• Bias audits: Take a look at quarterly whether or not sure segments (via area, corporate dimension, personality) are systematically appreciated or disfavored via scoring or personalization fashions. Regulate coaching records and lines to right kind imbalances.

Get started easy: one proprietor, one reviewer, and a weekly 15-minute check-in. Upload governance layers as your ML footprint expands.
