ActiveCampaign vs Mailchimp Pricing: What Each Costs at 1,000, 5,000 and 25,000 Contacts

ActiveCampaign is the more expensive of the two at almost every list size once you compare like for like. At 5,000 contacts billed monthly, ActiveCampaign Plus is $179 against $100 for Mailchimp Standard. ActiveCampaign only wins at the very bottom of the ladder, where Starter at $19 edges Mailchimp Essentials at about $20. The interesting part is that the gap moves in opposite directions on the cheap plans and the mid plans.

Both platforms bill on contacts, both publish a tiered ladder rather than a meter, and both changed the rules about which contacts get counted. That makes the sticker comparison the easy half of this. Here it is first, then the part that actually decides your bill.

ActiveCampaign vs Mailchimp pricing, side by side

These are monthly list prices, so nothing here is discounted by an annual commitment on either side. The pairing is ActiveCampaign Plus against Mailchimp Standard, because those are the two plans a business with real automation needs actually shortlists, and ActiveCampaign Starter against Mailchimp Essentials for the entry comparison.

Mailchimp is cheaper in fourteen of the sixteen cells where both vendors publish a number. That is a clearer result than most head to head comparisons produce, and it is worth stating plainly before anyone reads a preference into it: on price alone, at these plan pairings, Mailchimp wins.

The two ladders move in opposite directions

What the table above hides is that the size of the gap is not constant. Expressed as a multiple, the entry plans and the mid plans do completely different things as your list grows.

Read the two columns together. On the entry plans, ActiveCampaign starts marginally cheaper and gets steadily more expensive relative to Mailchimp, reaching 1.7x by 10,000 contacts and then vanishing entirely, because ActiveCampaign does not offer Starter at 25,000. On the mid plans, ActiveCampaign starts at more than double and narrows to about 1.7x. The two columns converge on roughly the same multiple from opposite ends.

The practical version of that: if you are choosing on price at a small list, ActiveCampaign Starter is genuinely competitive and Mailchimp Standard is genuinely cheap. If you expect to be at 10,000 contacts inside a year, the entry plan advantage is gone and you should price the decision at the size you are heading for, not the size you are at. Picking ActiveCampaign Starter to save a dollar a month at 1,000 contacts commits you to the steeper curve.

An annual commitment on ActiveCampaign takes roughly 20 percent off its side of every row, which narrows things without changing the direction. ActiveCampaign Plus at 5,000 contacts drops from $179 to $145 against Mailchimp Standard at $100. Better, still not cheaper.

Why both published ladders are shakier than they look

Here is the part that moves more money than the tier difference, and neither vendor puts it on the pricing page. The two platforms count contacts differently, and both of them changed how recently enough that most comparison articles have it wrong.

Mailchimp bills on your total contacts, and subscribed, unsubscribed and non subscribed records all count until you manually archive them. It also prices on your peak contact count during the billing period, so a one off import you deleted the next day can still set the tier you pay for that month.

ActiveCampaign splits its customers by signup date. Its help center documentation states that for accounts created on or after 3 November 2025, every contact counts toward the limit regardless of list status, unsubscribed and bounced included. Accounts created before that date pay on active contacts only. So an ActiveCampaign quote is not even comparable to another ActiveCampaign quote unless you know when both accounts were opened.

Stack those two rules on a realistic list and the arithmetic stops being tidy. Take 9,000 people who still open your email plus 2,500 unsubscribes and hard bounces collected over four years. On Mailchimp, unarchived, you are an 11,500 contact account. On a post November 2025 ActiveCampaign account, you are also an 11,500 contact account, which lands you in the 25,000 tier at $489 a month on Plus rather than the 10,000 tier at $239. On a grandfathered ActiveCampaign account you are a 9,000 contact account and you pay the 10,000 tier price. Three quotes, one list.

Which means the highest return action available to you here is not choosing a vendor. It is archiving the dead weight before you get quoted on either platform. On both systems archiving is free, reversible and immediate, and it is the only price cut in this category that nobody is selling you. Working out which contacts are genuinely dead usually means asking your own data a question your reporting screen does not have a button for, and being able to ask that question in plain English instead of writing the query is what turns a quarterly intention into something you actually do.

What you give up by taking the cheaper option

Price is a fair way to choose only when the two things do the same job, and here they do not, quite. ActiveCampaign Plus includes the sales CRM, landing pages and standard segmentation, and it removes the five action ceiling that Starter puts on every automation. Mailchimp Standard has automations, but they are shallower, and the segmentation is less flexible. If you are running multi step lifecycle sequences with branching logic, the premium is buying you something real.

Seats are the other quiet difference and they favor neither vendor much. ActiveCampaign includes one seat on Starter and one on Plus, three on Professional and five on Enterprise. That surprises people, because a lot of republished pricing guides still show the older one, three, five and ten allocation. Extra seat pricing is genuinely disputed: published figures range from $12 a month to $39, and at least one source says it is not published at all. Get it quoted before you count on it.

The honest summary is that ActiveCampaign is not trying to be the cheap one. It is a deeper automation product with a CRM attached, priced accordingly, and roughly 1.7 to 2.2 times Mailchimp at matched tiers is the toll. If you need that depth, pay it. If your automations are a welcome sequence and a monthly newsletter, you are paying a CRM premium for a newsletter workload.

Which one should you actually buy?

Buy Mailchimp if your sending is campaigns plus a couple of simple automations, your list is over about 2,500, and nobody on your team is going to build branching logic. You will pay less at every size and the gap grows with your list.

Buy ActiveCampaign if the automation builder is the point: multi step sequences, conditional branching, behavioral segmentation, or a sales pipeline that needs to live next to the email. Also buy it if you are still small and want room to grow into, but price your budget on Plus rather than Starter so the number does not have to be revised.

Do not buy either one yet if the real problem is that your campaigns are not going out because nobody has written them. That is a common and expensive misdiagnosis. A platform bill is a bad way to solve a content problem, and the automation builder you are paying a premium for will sit empty either way. Our full ActiveCampaign pricing breakdown and the Mailchimp pricing breakdown go tier by tier if you want the complete ladders, the ActiveCampaign alternatives comparison covers what else is in that bracket, and the email marketing software comparison puts the rest of the category on the same basis.

AutoMarketer sits on the other side of that line. It does not send email and it does not replace either platform for sending. It reads your website, builds a brand profile and drafts the campaigns, the sequences, the blog posts and the ad copy from it, on flat plans that do not move when your list grows. If the writing is the bottleneck rather than the sending, paste your URL and look at what it drafts before you upgrade anything.

Where these numbers come from

The ActiveCampaign ladder is corroborated across two independent pricing trackers that reconcile to within a few dollars in every cell. Plan structure, seat counts and send limits were checked at activecampaign.com/pricing on 2 September 2026. The 3 November 2025 contact counting split is documented in ActiveCampaign help center material. The Mailchimp figures are its published US list prices, with the 25,000 contact Standard row given as a range because sources disagree there and we would rather show the disagreement than invent a number. Extra seat pricing on ActiveCampaign is disputed and labeled as such above.
