6 Best AI Automation Tools for Mailchimp in 2026
Mailchimp’s automation is Customer Journey Builder, and it is a capable canvas: branch on behavior, wait for a condition, tag, send. If your problem is a welcome series or an abandoned cart flow, it solves it and you already own it.
Two things it does not solve. The generative AI features sit on Standard and above, so a lot of accounts are paying for a plan whose AI they cannot see. And Journey Builder only knows what happened inside Mailchimp, which means the reply someone sent to your campaign, the call it produced, and the record that should have changed are all somewhere else.
Below are six tools that automate Mailchimp with AI, ranked by how much of that they cover.
TL;DR: The best AI automation tool for Mailchimp for most people is Carly, because it works the gap between a campaign and the rest of your business. Journey Builder handles in-Mailchimp flows and is included; check whether your tier includes the AI features before you count on them.
1. Carly
Carly is an AI agent with its own real email address, connected to Mailchimp, your mailbox, your calendar, and your CRM.
The work it takes is the work a campaign creates. Someone replies to a newsletter asking about pricing: Carly answers from your own material, books the call, adds the tag in Mailchimp, and updates the CRM. A webinar signup arrives: the contact is added to the right audience, the invite goes out, and a reminder is scheduled.
Ask it “who replied to Tuesday’s send and has not been followed up” and it answers, then does the following up.
What makes it different: Journey Builder reacts to Mailchimp events with a canvas you build. Carly starts from the conversation, decides which replies deserve which action, and reaches thousands of apps to finish the job. You describe what you want in plain language rather than dragging a journey.
Best for: Small teams where campaign replies land on one person and never get worked.
Pricing: Free Zapier-style workflows; AI agents from $35/month
Connect Mailchimp at carlyassistant.com/integrations. The mechanical parts, like adding a tag or filing a signup, can run as free Zapier-style workflows rather than agent time.
2. Customer Journey Builder
Mailchimp’s own automation canvas: triggers, branches, waits, tags, and sends. Included with paid plans, with up to 200 automation flows on Standard.
What makes it different from Carly: it is the right tool for lifecycle email and it is already in your bill. It is also confined to Mailchimp’s own events and audience. A journey cannot book a call or update a record in another system.
Best for: Welcome series, re-engagement, and cart recovery.
Pricing: Included with paid plans. See Mailchimp pricing
3. Intuit Assist in Mailchimp
Mailchimp’s generative AI: drafting subject lines and body copy, generating campaign variations, and suggesting segments.
What makes it different from Carly: it writes the campaign, which is genuinely useful, and it is a Standard-and-above feature. Essentials accounts at $13 a month do not get it. It also stops at the send.
Best for: Writing campaigns faster on Standard or Premium.
Pricing: Standard and above
4. Zapier
Connects Mailchimp to thousands of apps, typically adding subscribers from a form or another system and syncing tags back out.
What makes it different from Carly: unmatched reach, and every Zap is plumbing you define and maintain that fires on every match. See Zapier alternatives.
Best for: Keeping Mailchimp audiences in sync with other systems.
Pricing: Free plan; paid from ~$19.99/month
5. Make
A visual canvas with branching, loops, and data transforms across Mailchimp and thousands of apps, usually cheaper than Zapier for complex work.
What makes it different from Carly: more power, more canvas to build and debug. Carly trades the canvas for instructions in plain words. See Make alternatives.
Best for: Technical teams wiring Mailchimp into multi-step processes.
Pricing: Free plan; paid from ~$9/month
6. The Mailchimp Marketing API
A mature REST API covering audiences, campaigns, automations, and reporting, and a small service can drive all of it.
What makes it different from Carly: exact and yours to maintain, including auth, hosting, and rate limits. Carly gives you the same outcomes from a plain-language instruction with nothing to run.
Best for: Product teams syncing app events into Mailchimp.
Pricing: Included with your plan (your build time)

FAQ

What is the best way to automate Mailchimp with AI? Use Journey Builder for lifecycle email, since you already pay for it, and add Carly for the work a campaign creates: replies answered, calls booked, tags applied, records updated.
Can AI reply to people who respond to my campaigns? Yes. Carly reads the reply, answers from your own material, and books a call or routes it to you when the answer needs a person. That is the Mailchimp work most senders never get to.

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
