ActiveCampaign vs Mailchimp: Automation Tested Side by Side
Most comparisons of these two tools line up feature checklists and call it a day. That tells you nothing about whether the automation you have in mind will actually build.
So I built the same three workflows in both platforms and recorded where each one stopped me. A welcome series, a tag based lead nurture with a branch, and a re engagement flow.
The results were not close, but they were also not what the marketing pages suggest. Here is everything I found.
ActiveCampaign vs Mailchimp at a glance
| ActiveCampaign | Mailchimp | |
|---|---|---|
| Free plan | None. 14 day trial only | Yes. 250 contacts, 500 sends a month |
| Entry paid plan | Starter, $15 a month | Essentials, $13 a month |
| First real automation plan | Plus, $49 a month | Standard, $20 a month |
| Automation step ceiling | 5 on Starter, unlimited on Plus and up | 4 on Essentials, 200 on Standard and up |
| Conditional branching | Plus and above | Standard and above |
| Built in sales CRM | Yes, with pipelines and deals | No. Audience tools only |
| Learning curve | Steep. Plan a weekend | Gentle. Plan an afternoon |
| Best for | Lifecycle marketing and B2B nurture | Newsletters and simple e commerce flows |
Read that table twice, because one row does most of the work. The plan that unlocks branching is not the plan either company advertises.
Why automation is the only round that matters
Broadcast email is close to a solved problem. Both tools will send a newsletter that lands and looks fine.
Automation is where the money actually sits. Automated emails make up roughly 2 percent of all sends but drive about 37 percent of email revenue, according to Omnisend’s 2026 benchmark data.
Automated flows produce about 41 percent of email revenue from just 5.3 percent of sends.Klaviyo, 2026 ecommerce benchmarks across 183,000+ brands
Klaviyo is a different platform, but the ratio holds everywhere. A small slice of triggered volume carries most of the return.
That is also why email still returns about $36 for every $1 spent, per Litmus. And why HubSpot puts automation among the three tactics marketers rate most effective, alongside segmentation and personalisation.
So a $5 a month price difference is noise. A platform that blocks the automation you need is not.
If you want the wider context first, my email marketing software guide covers how all the major platforms compare.
How I tested
I set up an account on each platform and built the same three workflows from scratch. Same trigger logic, same email count, same tags.
I timed each build and noted every point where the interface stopped me or forced a workaround. Then I checked each block against the official documentation to confirm it was a plan limit and not a mistake on my end.
Every limit quoted below is confirmed in the vendor’s own help centre. Links are included so you can verify each one yourself.
Test 1: a five email welcome series
This is the first automation almost everyone builds. Someone subscribes, then receives a short sequence over about ten days.
Welcome emails earn an average open rate above 83 percent according to GetResponse benchmark data, which makes this the highest value flow most small sites will ever run. It is also the flow both entry plans quietly refuse to build.
What happened in Mailchimp
The Customer Journey builder is genuinely pleasant. Pick a starting point, drag in a send, drag in a wait, repeat.
On Essentials I hit the wall at step four. Mailchimp’s own documentation confirms it: flows are capped at 4 steps on Essentials and only reach 200 steps on Standard.
Four steps means two emails and two waits. That is not a welcome series, that is a greeting.
What happened in ActiveCampaign
Same story, different number. On the Starter plan I got five actions and then the builder refused more.
ActiveCampaign documents this plainly in its help centre: Starter plans can have up to five actions in an automation. An email, a wait, an email, a wait, an email uses all five and leaves no room for a tag.
On Plus the ceiling disappeared completely. I built the full five email sequence with tags and a goal step in about twenty minutes.
Result: Both entry plans fail Mailchimp Standard and ActiveCampaign Plus both pass comfortably. Mailchimp was faster to build. ActiveCampaign gave me more control over what happened between sends.
Test 2: a lead nurture flow with a conditional branch
Here the sequence splits. Subscribers who clicked the pricing link go down one path, everyone else goes down another.
This is the single feature that separates an email tool from an automation tool. It is also gated on both platforms.
What happened in Mailchimp
Standard unlocks two split types. A conditional split routes contacts down one of two paths based on up to five conditions, and a percentage split divides them for testing.
Both worked exactly as described. The limitation is that a conditional split gives you two paths, not three or four.
To model a four segment routing, I had to nest splits inside splits. It works, but the canvas gets messy fast and the 200 step ceiling starts to feel closer than it sounds.
What happened in ActiveCampaign
ActiveCampaign gave me more ways to solve the same problem. If and else conditions, split actions, wait until conditions, and goal steps that let contacts skip ahead when they convert.
The goal step is the one I missed most in Mailchimp. It lets a contact who buys jump straight out of the nurture sequence instead of receiving three more emails selling them something they already own.
ActiveCampaign also has go to and jump to actions, which let you loop contacts back or move them between automations. That is real workflow logic, not just a decision tree.
Result: ActiveCampaign wins clearly Mailchimp branches. ActiveCampaign orchestrates. If your flows need goals, loops, or handoffs between automations, Mailchimp will make you build workarounds.
Test 3: a re engagement flow with behavioural triggers
The trigger here is absence. Someone has not opened an email in ninety days, so they enter a win back sequence and get tagged based on how they respond.
What happened in Mailchimp
Mailchimp handles this through segments plus a journey. You build the inactive segment, then use it as a starting point.
It works, but the setup is two jobs instead of one. And segment membership updates on Mailchimp’s schedule, not instantly, which makes precise timing harder to control.
Standard does add predictive and behavioural segmentation, which is a genuine step up from Essentials. Purchase likelihood and engagement scoring are useful if you run a store.
What happened in ActiveCampaign
ActiveCampaign treats behaviour as a first class trigger. Site tracking, event tracking, engagement scoring, and date based conditions all fire automations directly.
I set the flow to trigger on a contact’s engagement score dropping below a threshold. No intermediate segment required.
Lead scoring is the piece Mailchimp has no equivalent for. Being able to add or subtract points across a contact’s whole history, then automate off the total, changes what you can build.
Result: ActiveCampaign wins Mailchimp usable Mailchimp gets there with an extra step. ActiveCampaign gets there directly and gives you more signals to trigger on.
What it actually costs to run automation on each
Both companies advertise a low entry price for a plan that cannot run branching automation. So the advertised prices are close to meaningless for this comparison.
Here is what the automation capable tiers really cost.
| Mailchimp Standard | ActiveCampaign Plus | |
|---|---|---|
| Entry price | $20 a month, 500 contacts | $49 a month, 1,000 contacts |
| At 5,000 contacts | About $100 a month | Check the live calculator |
| At 10,000 contacts | About $135 a month | $189 a month annual, $239 monthly |
| Monthly send limit | 12x your contact count | 10x your contact count |
| User seats included | 5 | 1 |
| Automation steps | Up to 200 per flow | Unlimited |
| Charged for unsubscribes | Yes, unless you archive them | Yes on accounts opened after 3 Nov 2025 |
| Landing pages | Included | Included on Plus, not on Starter |
Mailchimp is cheaper at every list size on paper. ActiveCampaign closes some of that gap by including a sales CRM you would otherwise buy separately.
The billing detail that catches people out
Both platforms charge you for contacts who have already unsubscribed. They stay in your audience and count toward your tier until you archive or delete them.
If a third of your list has churned over the years, you are paying for a third more contacts than you can email. Audit your list before you compare quotes, not after.
ActiveCampaign changed this policy on 3 November 2025. Accounts opened before that date are still billed on active contacts only, and newer accounts are billed for unsubscribed, bounced, and unconfirmed contacts too.
If subscriber only billing matters to you, MailerLite and Kit both handle it more transparently.
Where Mailchimp genuinely wins
I have been hard on Mailchimp’s automation, so let me be fair about the rest.
- Speed to first send. I had a campaign designed and scheduled in Mailchimp in under fifteen minutes. ActiveCampaign took closer to an hour.
- The template library. Mailchimp’s designs still look better out of the box, and the drag and drop editor is more forgiving.
- A permanent free plan. It is thin at 250 contacts and 500 sends, but it exists. ActiveCampaign has no free tier at all.
- Integration breadth. Almost every tool with an email integration supports Mailchimp first.
- Five seats on Standard. ActiveCampaign Plus gives you one, which matters for any small team.
If your email programme is a monthly newsletter plus one or two simple flows, Mailchimp is the better tool and the cheaper one. Read my full Mailchimp review for the complete picture.
Where ActiveCampaign genuinely wins
- Automation depth. Unlimited actions, goals, loops, and automations that hand contacts to each other.
- Lead scoring. No Mailchimp equivalent, and it unlocks a whole category of behavioural automation.
- A real sales CRM. Deal pipelines and stages that automations can move on their own.
- Site and event tracking. Page visits and custom events become triggers rather than data you have to interpret later.
- Attribution reporting. On Professional and above you can see which automation produced which revenue.
The cost is complexity. ActiveCampaign has more ways to build the wrong thing, and more settings that will quietly do nothing if you misconfigure them.
My full ActiveCampaign review goes deeper on the builder and the add on pricing.
Which one should you choose
Choose ActiveCampaign if
- Your flows branch, loop, or need to end early when someone converts
- You track leads through stages and want the CRM in the same tool
- You sell something with a considered buying cycle
- You will use lead scoring and site tracking, not just admire them
- You can budget $49 a month or more from day one
Choose Mailchimp if
- Your main job is a newsletter with a couple of simple flows
- You want to be sending this afternoon, not next weekend
- Design quality matters more than logic depth
- More than one person needs an account
- You want a free plan to test the water first
One thing worth saying plainly. Do not buy ActiveCampaign Starter or Mailchimp Essentials expecting to automate.
Both are broadcast plans with an automation tab attached. You will hit the ceiling inside a fortnight and pay to upgrade anyway.

Two alternatives worth a look first
Neither of these tools is the automatic answer for a small site. Both charge more than they need to for what most people actually build.
MailerLite gives you branching automation on plans that cost a fraction of ActiveCampaign Plus. The builder is simpler, but it clears the bar most small businesses need.
Kit, formerly ConvertKit, is built around visual automations and tag based subscriber management. If you are a creator selling courses or a newsletter, it fits better than either tool here.
I compared those two directly in my MailerLite vs Kit head to head.
Frequently asked questions
Is ActiveCampaign better than Mailchimp?
For automation, yes. ActiveCampaign supports unlimited automation actions, goal steps, loops, lead scoring, and a built in sales CRM that Mailchimp does not offer. For ease of use, template design, and entry price, Mailchimp is better. The right answer depends on whether your workflows branch.Can I run a welcome sequence on Mailchimp’s free plan?
No. The free plan covers 250 contacts and 500 sends a month with a 250 email daily cap, and multi step customer journeys are not included. You need at least the Standard plan at $20 a month to build a proper multi step welcome series with branching.What is the cheapest ActiveCampaign plan that supports branching automation?
Plus, at $49 a month for 1,000 contacts on annual billing. The Starter plan caps every automation at five actions and does not support conditional branching, which rules out most real sequences.Does ActiveCampaign have a free plan?
No. ActiveCampaign offers a 14 day free trial only, which is limited during the trial period. Mailchimp is the only one of the two with a permanent free tier.Is it hard to migrate from Mailchimp to ActiveCampaign?
Contacts, tags, and lists import without much trouble. Automations do not transfer, so you rebuild them by hand. ActiveCampaign offers a free migration service on paid plans, which is worth using if you have more than a handful of flows.Which platform has better deliverability?
Neither wins by default. Independent testers find both land reliably when you authenticate your domain with SPF, DKIM, and DMARC and keep your list clean. Your sender reputation matters far more than the logo on your dashboard.
The verdict
ActiveCampaign is the better automation platform, and it is not particularly close. Goals, loops, lead scoring, and automations that talk to each other are things Mailchimp simply does not do.
Mailchimp is the better starting point. It is cheaper, faster to learn, better designed, and it has a free plan you can test on tonight.
The mistake to avoid is buying either company’s cheap plan for automation. Mailchimp Essentials stops at four steps and ActiveCampaign Starter stops at five, so budget for Standard or Plus from the start or pick a tool that does not gate branching at all.
