Mailchimp Pricing for AI Email Marketing: Plans, Contact Tiers and Real Costs

Who This Guide Is For

This page is for buyers who care about two questions at once: which AI features they can use on a given plan, and what that plan costs at their real list size. Mailchimp answers the first question well for small teams. Its contact-based pricing answers the second question only once you have counted your contacts.

How Mailchimp Prices Its Plans

Mailchimp's paid plans are sized by contact count. The pricing page lists a Free plan at $0 for up to 250 contacts, one audience and up to 500 sends a month, with a cap of 250 sends per day. Paid plans step up by contact band, and each band comes with its own monthly send allowance. The contact bands in the pricing read used for this guide are $100 a month for 2,501 to 5,000 contacts (up to 60,000 emails a month), $135 a month for 5,001 to 10,000 contacts (up to 120,000 emails a month) and $230 a month for 10,001 to 15,000 contacts (up to 180,000 emails a month).

Two entry rows sit below those bands. Essentials is listed at $13 a month for 500 contacts on monthly billing. Standard is listed at $20 a month for the default 500-contact selector, with up to 6,000 emails a month at that size. The pricing page associates Standard with behavioral targeting and advanced journeys, so check the feature list there before you choose between the two rows.

Mailchimp also offers a 14-day Standard trial, and the pricing page shows a free-month Premium offer. A trial lets you test the AI helpers on your own list before you commit to a tier. Make a note of the trial end date, because the plan you were testing may not be the plan you are billed for afterwards.

Counting rules for unsubscribed and archived contacts have changed over time. Before you assume that removing inactive profiles will drop you to a lower band, check the current rules on the pricing page and audit your audience structure yourself.

AI Email Marketing Tools Compared on Entry Price

The table below sets Mailchimp beside the other tools in this lab's ranking that a small team is most likely to shortlist. Prices are the starting figures listed on each vendor's pricing page. None of the listed prices includes a separate AI add-on, because the pricing pages read for this guide did not list one.

Read the table with your own numbers beside it. Two rows that look similar on price can differ sharply once the list passes a band boundary, and the limitation column is usually the reason a plan stops working before the budget does.

What Mailchimp Costs at Real List Sizes

The clearest way to price Mailchimp is to find your contact count in the table below and read across. Each row shows the plan or band that applies, the monthly price listed and the send allowance that comes with it. Where the pricing read did not show a price for a size, the table says so rather than estimating.

Derived arithmetic makes the jumps easier to budget. At 5,000 contacts the listed price is $100 a month, which is 12 × $100 = $1,200 a year. At 10,000 contacts it is $135 a month, or 12 × $135 = $1,620 a year. Moving from the top of one band to the next adds $420 a year in that range, before any other cost changes.

For a list larger than the table, the pricing read used for this guide does not show a price, so the honest answer is pricing on request. Ask Mailchimp for a quote before you plan a budget above 15,000 contacts, and ask which AI helpers are included at that size.

AI Writing and Optimization: What to Verify on Mailchimp

Mailchimp lists content helpers and send-time helpers among its product features. Those are the AI-adjacent capabilities that matter for this guide. Treat them as items on a checklist rather than as the reason to buy. Feature access is tied to the plan you select, so confirm which plan includes each helper on the pricing page before you commit to a row in the cost table.

The prices in this guide are plan prices. The pricing page read for this guide did not list a separate AI add-on fee, so the monthly figures are the figures to budget against. If you later see a per-use charge on an invoice, check the terms, because that would change the calculation.

A practical check takes about an hour. Build one welcome email on the Free plan with the content helper, rewrite the draft by hand, and note how much editing it needed. Repeat with a second email. If the helper saves time on your own copy, the Essentials or Standard row becomes easier to justify. If you end up rewriting everything, the feature is not doing the job, and the money is better spent on the tool that fits your copy.

Send-time helpers depend on data. On a list of 250 contacts, a suggested send time is a guess. On a list of several thousand active subscribers, the same suggestion has more history behind it. Judge the helper on the list you actually have, and revisit the judgment when the band changes.

Mailchimp: Strengths and Limits for AI-Focused Small Teams

Mailchimp's main strength is familiarity. The editor, the template library and the integrations are widely known, and a team that already keeps its list in Mailchimp can test AI helpers without a migration. For a small list, the Free plan and the Essentials row give a clear, low-risk starting point, and the monthly bill is easy to explain to a non-technical owner.

The main limit is the meter. Every contact in the audience counts toward the band, including people who stopped engaging months ago. A list with many inactive contacts pays for them at the same rate as active subscribers. Growth also moves the price without any change in your campaigns. A list that grows from 5,000 to 10,000 contacts moves from the $100 band to the $135 band, which adds $420 a year with no change in what you send.

Price for this tool: Free at $0 for up to 250 contacts, Essentials from $13 a month at 500 contacts, Standard from $20 a month at 500 contacts, and contact bands from $100 a month at 2,501 to 5,000 contacts. Full details are on the Mailchimp pricing page.

Mailchimp suits a team whose list is mostly engaged subscribers and whose AI needs are modest. It suits a team less well when the list is dominated by inactive or trial contacts, because the bill then grows with contacts that will never open an email.

Alternatives Worth Pricing Against Mailchimp

Mailchimp is not the only sensible choice. Each tool below prices differently, and the difference matters once your list or send volume grows. Confirm AI features on each vendor's pricing page, because this guide prices only what those pages list.

Brevo: monthly volume pricing

Brevo prices by monthly email volume rather than by contact band. Its Free plan allows 300 daily sends with storage for up to 100,000 contacts. Starter is listed at $9 a month, starting at 5,000 emails a month with no daily sending limit, and Standard at $18 a month adds automation, A/B testing and advanced reports. For a small team, the daily cap on the free plan and the jump to Professional, listed at $499 a month for 150,000 to 10 million monthly sends, are the points to test. Pricing: brevo.com/pricing.

ActiveCampaign: segmentation and CRM workflows

ActiveCampaign suits teams that need segmentation and CRM-style workflows. Its four plans are Starter at $15 a month, Plus at $49, Pro at $79 and Enterprise at $145, and each starting price applies at 1,000 email contacts. Advanced segmentation begins at Pro, and the pricing page offers a free trial without a stated duration in the read used here. The limitation is cost at scale: every plan's starting price rises with the contact count, so a large list pays more for the same features. Pricing: activecampaign.com/pricing.

Kit: a free plan for creators

Kit fits creators and newsletter writers. The Free plan covers up to 10,000 subscribers with unlimited landing pages, forms and email broadcasts, plus audience tagging and segmentation. Visual automations and email sequences start on Creator, listed at $33 a month billed annually, which also adds A/B testing of subject lines. A 14-day trial on paid plans needs no credit card. The limit for a team that wants automation on day one is that the free plan stops short of visual automations. Pricing: kit.com/pricing.

Loops: product email with a subscribed audience

Loops suits product teams sending to a subscribed audience. Its Early Stage plan is free for up to 4,000 sends in any rolling 30 days, with all features included, but it adds a Loops footer and limits sends to the 1,000 newest contacts. The Growing Audience plan is listed at $99 a month with unlimited sends to subscribers and transactional sends to users outside the audience. The trade-off is the send cap on the free plan, which matters once the list is larger than 1,000 contacts. Pricing: loops.so/pricing. Pricing guide: Loops pricing guide.

Customer.io: event-driven messages with AI Agent tools

Customer.io is built around messages triggered by product events. Essentials is listed at $100 a month on monthly billing and includes AI Agent core skills, a visual workflow builder, email and community support and basic data integrations. Premium is listed from $1,000 a month with custom profile volume, elevated AI Agent limits and premium support. Eligible early-stage companies that have raised under $10M can receive 12 months free through the Startup Program. The weak point is forecasting: pricing combines profiles and email volume, so the bill is harder to predict than a flat contact count. Pricing: customer.io/pricing. Pricing guide: Customer.io pricing guide.

Sender: the low-cost option

Sender is the lowest-cost option in this group for small lists. The Free Forever plan covers 2,500 subscribers and 15,000 emails a month. Standard is listed at $6.30 a month for 6,000 emails and 500 subscribers, and Professional at $10.50 a month for 12,000 emails and 500 subscribers. The limit is the 500-subscriber cap on paid plans, so a list that grows past that point has to move to a different plan or a different tool. Pricing: sender.net/pricing.

Which Tool Fits Which Requirement

Use the table below to match a requirement to a tool. Each row names the plan and the reason, so you can check it against the vendor's page before you buy.

How to Choose

Start with three numbers: your current contact count, your expected monthly sends and whether you need automations or only broadcasts. Those three numbers narrow the field faster than any feature list. A team with 500 contacts, a weekly newsletter and no automation needs a different plan from a team with 40,000 contacts and daily product messages.

For AI help without learning a new tool, Mailchimp is the straightforward pick at small list sizes. For the lowest cost on a list up to 2,500 subscribers, Sender's free plan is worth testing. For event-driven product messages with AI Agent tools, Customer.io Essentials is the entry point to price. The right test in every case is whether the AI helper saves editing time on your own copy, not on a demo.

Do not choose on the AI label alone. Most listed AI features sit on specific plans, and the real cost is the plan price plus any add-ons. Write down the plan, the feature and the monthly figure for each tool before you compare totals. Then compare the totals at the contact count you expect in twelve months, not the one you have today.

If you are already on Mailchimp, the cheapest move is often to stay until a band change forces the decision. Price the next band, check the AI features on the plan you would need, and only then decide whether a switch is worth the migration effort.

Setup and Migration Checklist

Whether you stay on Mailchimp or move, the same steps decide the bill. Work through the checklist in order, because each step depends on the one before it.

Migration adds one cost that a pricing table does not show: the time to rebuild templates, automations and tags. Budget that time against the monthly saving, and do not switch mid-campaign. Move the smallest segment first, confirm sends and suppression behave as expected, and then move the rest.

How This Page Was Prepared

This guide reflects the pricing pages of each vendor as read on 7 October 2026. Prices are shown as monthly figures unless the vendor's page shows a different billing view, in which case the billing view appears in the table. Where a price was not listed for a size or tier, the page says pricing on request rather than estimating. Feature descriptions are limited to what the vendor pages list.
