ActiveCampaign vs Mailchimp: which should you pick?

Ask one question and this comparison answers itself: are your emails scheduled, or triggered? If you decide on a Tuesday to send something on Thursday, Mailchimp is built for you and is easier. If the email should go because somebody filled in a form, abandoned a cart or looked at the pricing page twice, ActiveCampaign is built for that and Mailchimp will frustrate you.

Most comparisons in this category turn into feature lists. The feature lists both look good. The difference is what each product assumes you are doing.

ActiveCampaign vs Mailchimp at a glance

Where Mailchimp genuinely wins

It is free to start. ActiveCampaign has no permanent free plan, only a 14-day trial. For somebody with 200 subscribers and no revenue, that is the whole decision and no amount of automation depth changes it.

The editor is better. Mailchimp's template library and drag-and-drop editor let a non-designer produce a decent-looking email quickly. ActiveCampaign's editor is capable and is one of the recurring complaints in its reviews — people describe formatting frustrations and fighting the layout.

Everyone knows it. If you will eventually hand this to a freelancer, a VA or an agency, the chance they already know Mailchimp is much higher. That is a real operational cost difference that never appears on a feature table.

It is simpler to not use badly. ActiveCampaign gives you enough rope to build an automation nobody understands six months later. Mailchimp's shallower logic is a limitation and also a guardrail.

Where ActiveCampaign is not close

Anything triggered by behaviour. ActiveCampaign can start a workflow from a page visit, a link click, a score crossing a threshold, a purchase, a tag change, a date field or an event from a connected app — then branch on what happens next, wait for a condition, score the contact and hand them to a different path.

Mailchimp's customer journeys do a version of this and stop considerably earlier. The practical test: if you have ever described what you want as "and then if they don't click, do this instead, but only if they're on the paid plan", you are describing ActiveCampaign.

Lead scoring is the other genuine gap. ActiveCampaign scores contacts on behaviour and lets the score drive logic or alert a person. Mailchimp has nothing equivalent, and for anyone doing sales follow-up that is the feature that decides it.

Price, which is not the simple comparison it looks

ActiveCampaign is $15 a month at 1,000 contacts and $49 for the Plus plan most automation users actually need. Mailchimp's free tier is free and its paid tiers rise steeply with list size — the two cross over at different points depending on how many contacts you hold and which features you use.

Two counting rules matter more than the sticker price. ActiveCampaign, on accounts created from 3 November 2025, counts every contact toward the limit including unsubscribed and bounced — so a messy legacy list costs money here. Mailchimp handles archived contacts differently, which is friendlier to a business with history.

And ActiveCampaign's send allowance is a second quota: 10× your contact limit per month on Starter and Plus. A 1,000-contact list is 10,000 sends, and every automation email counts. Our pricing breakdown works through both.

Switching, in either direction

Moving a list between these two is straightforward — contacts and tags export as CSV and import cleanly. What does not move is the automations, which have to be rebuilt by hand because the two products model logic differently.

That is the real switching cost and it is worth counting before deciding. A business with three simple journeys can move in an afternoon. A business with fifteen interlocking automations, tags and conditions is looking at a project, and the honest advice is to rebuild only the ones that are still earning rather than recreating everything faithfully.

Our migration guide covers the sequence, including the part most people get wrong: warming the new sender rather than switching all traffic in one day.

Which should you pick?

• You are starting out with a small list and no budget. Mailchimp's free tier. Come back to this question when the list earns something.
• You send a newsletter and occasional campaigns. Mailchimp. ActiveCampaign is more product than the job needs.
• Your marketing is triggered by what people do. ActiveCampaign, on Plus rather than Starter.
• You need lead scoring and sales follow-up. ActiveCampaign, and price the pipelines add-on.
• Your whole business is an online store. Look at Klaviyo before either.
• You want deliverability and a phone number to ring. AWeber is the quieter option neither of these matches on support.

Deliverability, and why neither is the differentiator

Both platforms deliver competently and both will fail a list that was bought, scraped or neglected. The thing that decides inbox placement is almost never the vendor.

What does decide it: whether SPF, DKIM and DMARC are set on your sending domain; whether people actually opted in; whether you send consistently rather than in bursts after six months of silence; and your complaint rate. Those are the same on either platform and they are yours.

Where the two differ slightly is the tooling around it. ActiveCampaign separates transactional email onto Postmark as a distinct product, which is the better architecture — a marketing reputation problem should never be able to stop a password reset arriving. Mailchimp's transactional offering is also separate. Either way, do not send receipts from the same reputation as your newsletter, and our piece on how sender reputation works explains why that separation matters more than any feature comparison.

Which one your team can actually run

The cost that never appears in a comparison table is who maintains it.

Mailchimp is widely known. If you hand the account to a freelancer, a virtual assistant or an agency, the odds they have used it before are high, and the documentation and community answers for any question are extensive.

ActiveCampaign is known by specialists. The people who know it know it well, and there are fewer of them. For a business that expects to outsource email at some point, that is a real consideration — and the flip side is that an ActiveCampaign specialist will build you something a Mailchimp generalist cannot.

The practical test: if the person who sets this up leaves, can the next person understand it? A Mailchimp account is usually self-explanatory. An ActiveCampaign account with fifteen interlocking automations is only self-explanatory if whoever built it named things properly — which our automation guide argues for at some length.
