ActiveCampaign Pricing vs Mailchimp: Cost Per Contact Compared

Mailchimp is cheaper than ActiveCampaign at almost every contact level the two share, and the real gap is wider than the sticker prices suggest, because every price ActiveCampaign publishes requires a twelve month commitment while Mailchimp's does not. That single structural difference is missing from nearly every comparison of these two platforms, and it changes the answer at every band.

We read both ladders directly from the vendors rather than from roundups: ActiveCampaign's fifteen contact bands from its own pricing selector with the currency forced to USD, and Mailchimp's twenty bands the same way. Below is what they cost side by side, where they cross, and the two policy details that matter more than either price.

ActiveCampaign vs Mailchimp entry plans, band by band

ActiveCampaign Starter and Mailchimp Essentials are the two entry plans. Their contact bands do not line up perfectly, so this table only shows the levels both vendors actually publish.

The shape of that table is more interesting than any single row. The two plans start $6 apart with ActiveCampaign cheaper, diverge to $121 apart at 25,000 contacts with Mailchimp cheaper, then come back to within $6 of each other at 50,000. Whoever wins depends entirely on where your list currently sits.

The convergence at the top happens because both entry plans have a price ceiling. Mailchimp Essentials tops out at $385, and ActiveCampaign Starter tops out at $391. ActiveCampaign's ceiling arrives earlier, at 25,000 contacts against Mailchimp's 50,000, and that is the one part of this comparison where ActiveCampaign's structure is friendlier. Above 50,000 contacts ActiveCampaign Starter stays at $391 all the way to 200,000 contacts, which works out to roughly $0.20 per thousand emails sent.

The mid tier plans are not close

Most buyers comparing these two are actually comparing the middle plans, because that is where the automation lives. Here Mailchimp wins at every shared band.

ActiveCampaign Plus costs between 15 and 58 percent more than Mailchimp Standard depending on the band, and it also gives you fewer sends. Mailchimp Standard allows 12 times your contact tier per month. ActiveCampaign Plus allows 10 times, the same multiple as ActiveCampaign's own entry plan. Upgrading from Starter to Plus buys features, not sending headroom.

There is one seat detail that catches teams out. ActiveCampaign Starter and Plus each include exactly one user, so a second person needing a login pushes you to Pro. At 10,000 contacts that takes the bill from $189 to $375 a month, a 98 percent increase for one extra seat.

Why the annual commitment changes every row above

Here is the correction that most comparisons miss. ActiveCampaign's pricing page has no month to month toggle. The billing label under every plan card reads "Billed annually," and the word monthly appears on that page only as the "/mo" unit beside the number. Month to month billing exists at checkout and costs more, but ActiveCampaign does not publish those figures.

Mailchimp does the opposite. Its published prices are month to month, and its annual arrangement is a promotional discount rather than a standing prepay rate.

So every table above is comparing an ActiveCampaign price that locks you in for a year against a Mailchimp price you can cancel next month. On a genuine like for like monthly basis, ActiveCampaign is more expensive than it appears everywhere, and its narrow $6 win at 2,500 contacts almost certainly disappears. If you want month to month from ActiveCampaign, get that number at checkout before you sign, not after.

What each platform actually counts as a contact

Two different billing bases sit under these ladders, and they fail in different directions.

ActiveCampaign charges by band. At 25,001 contacts you pay exactly what someone with 30,000 pays, so a band bottom account carries a much worse per contact rate than a band top account. Deleting a handful of addresses right after a band boundary can drop the bill a full step.

Mailchimp charges on your peak contact total during the billing cycle, not the count at the end of it. A one day spike from an import or a campaign landing page is billed for the whole month even if you clean the list the next morning. Mailchimp also bills unsubscribed and non subscribed contacts, and a person who appears in three audiences is billed three times.

In practice that makes Mailchimp punish messy list hygiene harder, and ActiveCampaign punish sitting just over a boundary harder. Neither is cheaper in the abstract. Both reward knowing exactly how many addresses you store, which is a number most teams cannot state on demand.

Can you send cold email on either one?

No, and this is where the pricing question usually stops mattering. Both platforms prohibit outbound prospecting in their own terms, and ActiveCampaign's wording is the stricter of the two.

ActiveCampaign's Anti-Spam Policy bans "any form of paid, rented, borrowed, etc. lists" and says that subscribers who did not opt in through your own process "cannot be imported." Then it goes further than any comparable policy we have read: "simply getting someone's business card is not an acceptable opt-in and you cannot import or send to emails that you have obtained from business cards." A card handed to you at a conference is not consent under that rule, which settles the question for any bought or scraped prospect list.

Mailchimp's acceptable use terms ban purchased, rented, third party, co-registration, publicly available data and partner lists of any kind. Same outcome, slightly gentler wording.

Both enforce through bounce, unsubscribe and complaint monitoring, and ActiveCampaign states it receives complaint data directly from ISPs. Accounts with abnormal rates are put under review, and ActiveCampaign's Terms of Service allow suspension at its sole discretion. Paying for a bigger contact tier does not buy permission.

So which one should you buy?

If you are nurturing a list that opted in, the honest answer is that Mailchimp is cheaper at most sizes and ActiveCampaign's automation builder and CRM are meaningfully better. That is a real trade rather than a trick question. Pick ActiveCampaign if you will actually build multi step automations and want a CRM in the same tool. Pick Mailchimp if your sending is mostly campaigns and newsletters and you want to stay month to month.

A useful third comparison point is Constant Contact's thirteen band ladder, which starts cheaper than either at $12 and has the steepest single step of the three, a 150 percent jump at the 501st contact.

Both vendors bill you for every address you keep, which quietly turns the source of your list into a line item. Contacts that arrive from search traffic cost nothing per head to acquire, so over a couple of years the most effective way to hold either bill down is usually to publish content that ranks rather than to keep buying reach and paying to store the results.

And if what you actually need is to reach people who have never heard of you, neither platform is the answer, because neither one permits it. Outbound runs on your own domains and your own SMTP, and it bills on emails sent rather than contacts stored. We keep the full cold email software pricing comparison updated for that case, along with a guide to the best SMTP providers for cold email.
