Mailchimp’s 2026 Price Increase (and What It Means for You)

Mailchimp's 2026 price increase is two separate changes. The Free plan now allows 250 contacts and 500 sends a month. Several industry sources also report an average 11 to 13% increase on certain legacy plans, starting with billing cycles after April 13, 2026.

Most Mailchimp customers aren't on a legacy plan. Any bill can still rise when you cross a contact or send threshold, add a paid channel, or need a higher tier. This guide covers the legacy-plan increase, current plan prices, billing rules, feature access changes, cost scenarios, and what to do before your next renewal.

A headline percentage rarely matches your own bill. Your bill also moves with audience size, add-ons, and duplicate contacts, so an 11% notice can land very differently on two accounts.

Two changes happened, and they affect different customers.

The Free-plan change cuts capacity instead of raising a sticker price, but it moves up the point where a small business has to pay. The legacy change directly raises the recurring price for affected accounts.

That difference matters for planning. A price increase fits into a budget, because your business runs the same way and you add the new cost. A lower limit forces a choice between paying for the next tier, sending less, or removing contacts, and none of those guarantees the same growth.

Current Essentials, Standard, and Premium prices are covered separately below. The reported April increase appears specific to grandfathered legacy plans and doesn't apply to every Mailchimp customer.

Legacy plan customers and Free plan users are the most directly affected, and every other paid customer can still see a higher bill as their account grows.

How to identify a legacy plan:

• Your account predates Mailchimp's May 2019 pricing model.
• Your plan name doesn't match Essentials, Standard, or Premium.
• Your account received a pricing-update notice.

Open Account & Billing to confirm your plan name, billing date, and next estimated charge.

How much more could your Mailchimp bill become?

Your bill rises by the reported 11 to 13% if you're on an affected legacy plan, and by the price of the next plan if you outgrow a limit. Three scenarios show the difference.

These figures exclude taxes, add-on contact blocks, SMS, and transactional email. Contact tiers above 500 cost more, so price your own list with Mailchimp's plan calculator.

To find your real 12-month cost, fill in this worksheet, then multiply by 12 and run it again with your forecast contact count.

Clearing inactive contacts first lowers the count you pay for. One ActiveCampaign customer who prunes inactive contacts regularly credits it with higher engagement.

Mailchimp's Free plan costs $0, and paid plans start at $13 for Essentials, $20 for Standard, and $350 for Premium each month.

Mailchimp advertises a 14-day free trial of Essentials and Standard and 15% off the first 12 months for businesses with 10,000 or more contacts. Promotions, annual offers, currencies, and local taxes can change the displayed amount.

Mailchimp calculates your bill from your plan type, your selected contact tier, and any additional charges or add-ons. These rules explain most surprises:

• Contacts count broadly. Subscribed, unsubscribed, and non-subscribed contacts all count toward your limit.
• Duplicates count twice. The same person in two audiences counts as two contacts, so a list that looks like 200 people can land above the Free plan's 250-contact limit.
• Archived and cleaned contacts don't count. Archive or clean records you no longer email.
• Peak contacts set the bill. Mailchimp charges against the highest contact total in the billing period. Uploading a large list for one send and deleting it afterward still bills at the peak.
• Overages add blocks. Exceeding the contact or send allowance can trigger one or more add-on contact blocks, and paid plans bill overages automatically.
• SMS and Transactional Email cost extra. Both bill separately from your plan.
• Test emails count. They use your monthly send allowance.

Why does Mailchimp bill per audience instead of per unique contact?

Mailchimp stores contacts inside each audience, so the same person in two audiences is two records and two billed contacts. Over a year, that means you pay for a higher contact count than the number of real people you email. It also works as a fit signal: if you run several audiences, you're paying for overlap, and the overlap makes it harder to tell which touchpoint drove a conversion.

Feature changes raise your real cost when they move something you use behind a higher plan, or when they create rebuild work.

• Classic Automations are a legacy capability. Only paid accounts that previously created one can use them. Mailchimp directs customers toward Marketing Automation Flows and offers a conversion process, but some classic features may not convert, which creates migration and QA work.
• Custom-coded templates and Inbox Preview mark a clearer tier boundary. Mailchimp's plan comparison says Free and Essentials can create custom-coded templates but must upgrade to send them. Its help documentation places custom HTML templates and Inbox Preview on Standard or higher.
• Other gates can force an upgrade. The table below shows where common features start.

When a vendor retires or gates a feature, the cost goes past the new price. Start by asking whether the feature exists only in this platform and your team truly needs it, or whether another tool you already use covers it. Moving tools also resets your history: you lose momentum, and any email account needs time to warm up and learn.

Mailchimp is still worth it for a small, stable list, straightforward newsletters or promotions, limited automation needs, and a team that's comfortable with the current contact, send, audience, and feature limits.

Decide based on your 12-month cost and the capabilities you need, instead of the headline percentage. A simple test is to model it: if you have 500 contacts today and expect 1,000, check whether your current plan still supports the segmentation, automations, and channels you'll need at that size. Also check how quickly the vendor ships product updates as AI changes marketing.

Two signals say it's time to look elsewhere: you run several audiences with different intent, or about three months of testing hasn't moved your results. Mailchimp fits teams focused on an immediate need. Teams planning for growth, more channels, or a bigger list often want a platform they won't have to leave.

1. Confirm your plan. Open Account & Billing and check your plan name, billing date, and next estimated charge.
2. Clean your list. Archive inactive and duplicate contacts before the billing period starts, because the peak total sets your bill. Sending to people who don't want your email also puts your sender reputation at risk.
3. Model 12 months. Use the worksheet above with your forecast contact count.
4. Check your feature gates. Compare the features you use against the table above.
5. Test before you commit. If you've outgrown your plan, run a free trial of an alternative with your own data.

When a Mailchimp price increase arrives alongside a need for deeper automation, personalization, reporting, or connected customer journeys, ActiveCampaign gives you a platform built to grow with you. These are the differences that matter most for the price discussion:

• Flexible multi-step automations. Build them visually, or describe a goal in plain language and have Active Intelligence create the campaign and automation.
• Deeper segmentation and personalization. Segment on behavior, and identify contacts who aren't engaging so you can exclude them before a send.
• Connected execution. Email, SMS, WhatsApp, CRM, and integrations work together.
• One contact count. ActiveCampaign counts a contact once, even when that person appears on multiple lists.

Active Intelligence also changes how you check results. You can ask a question from the outcome you care about, such as the ROI of a campaign. You get an analysis across your campaigns instead of raw data to dig through yourself. It recommends next moves and surfaces segments you hadn't noticed, so a small team can spend its time on judgment calls.

Plan availability varies, and not every AI, automation, CRM, or channel feature is included in the entry plan. Check the current ActiveCampaign pricing before you decide.

What migrating from Mailchimp looks like. ActiveCampaign's 2026 migration solution can bring over lists or audiences, contacts, tags and custom fields, forms, email campaigns or templates, and supported Classic Automations for review before import. Starting a migration now moves your account contents in one pass, so you don't need to choose item by item. Availability, eligibility, and asset support can vary, so follow the current migration guide for your setup.
