The Best Mailchimp Integrations and Apps in 2026
Mailchimp is where a lot of small businesses run email and SMS campaigns, signup forms, landing pages, and audience segments. But a list of subscribers is only worth what it’s connected to — the store where people buy, the CRM where deals live, the forms where leads come in. Mailchimp’s integration directory covers 300-plus native apps, and Zapier stretches that to thousands more.
Here are the Mailchimp integrations actually worth setting up, grouped by what they do — and then the way to connect Mailchimp to anything with an API, even when no native integration exists.
E-commerce: Shopify, WooCommerce, Squarespace, Wix, BigCommerce
Sync customers, orders, and product catalogs so campaigns can target real purchase behavior.
- Shopify — the flagship connector: syncs customers and orders, powers abandoned-cart and post-purchase automations, and pushes product data into emails.
- WooCommerce — connects your WordPress store so purchase data drives segments and product-recommendation blocks.
- Squarespace — links Squarespace Commerce customers and orders into your Mailchimp audience.
- Wix — syncs Wix Stores contacts and orders for follow-up campaigns.
- BigCommerce — pulls store data in for segmentation and automated flows.
CRM: Salesforce, HubSpot, Pipedrive
Keep contacts and marketing engagement in sync with the system your sales team lives in.
- Salesforce — a two-way connector that syncs leads, contacts, and campaign activity between Mailchimp and Salesforce.
- HubSpot — sync subscribers and engagement data so marketing and sales share one contact record.
- Pipedrive — push new Mailchimp subscribers into your pipeline and keep contact fields aligned.
Forms and content: Typeform, Jotform, WordPress, Canva
Capture leads and design campaigns without leaving your tools.
- Typeform — send Typeform respondents straight into a Mailchimp audience with tags.
- Jotform — route form submissions into your list, mapping fields to merge tags.
- WordPress — embed signup forms and popups on your site with the official plugin.
- Canva — design email graphics in Canva and drop them into Mailchimp campaigns, or pull Canva assets in while editing.
Social and ads: Instagram, Facebook, Google Ads
Run paid and organic social alongside email from one audience.
- Instagram & Facebook — publish posts and create retargeting or lookalike ad campaigns built on your Mailchimp audience.
- Google Ads remarketing — build audiences from your subscribers and run remarketing ads inside Mailchimp’s campaign tools.
Payments and accounting: Stripe, Square, QuickBooks, Xero
Tie revenue and financial data to your marketing.
- Stripe — connect payment data to trigger campaigns and track revenue against sends.
- Square — sync Square customers and sales into your audience for targeted follow-up.
- QuickBooks Online — sync contacts and real-time financial data between QuickBooks and Mailchimp.
- Xero — keep contacts aligned between your accounting and your email list.
No-code automation: Zapier and Make
- Zapier and Make — connect Mailchimp to thousands of apps with simple triggers (“new subscriber → do X”). Great for straightforward field-mapping, though they’re built for basic automation, not for reasoning over your data.
The AI way to connect Mailchimp to anything: Carly
Native connectors and Zapier cover the common apps. But the moment you need Mailchimp tied to a tool that isn’t in the directory — or you want something smarter than “new subscriber → copy field” — you’ve hit the ceiling of native integrations and no-code triggers.
Carly is an AI executive assistant that connects to 200+ tools — Mailchimp included — and lets you bring your own API key to connect to anything else with a REST API. Instead of a fixed catalog, you get an agent that:
- Acts on triggers, 24/7 in the cloud — when someone subscribes, a campaign finishes, or a contact hits a tag, Carly does the next step without you in the app.
- Reasons over your data — not just “copy this field,” but “read the last campaign’s opens and clicks, find the contacts who engaged twice, and add them to a warm-lead segment.”
- Ties Mailchimp to the rest of your stack — a new subscriber becomes one step in a workflow that also touches email (Gmail and Outlook), calendar, CRM, and tasks.
- Builds the workflow from a plain-English description — tell it “when a lead fills out our webinar form, add them to the nurture audience and send me a Slack summary” and it interviews you, then builds it.
AI agents start at $35/month, and steps in a workflow that don’t use AI run free and unlimited. Carly also integrates with Mailchimp.
How to connect Mailchimp to a tool with no native integration
- In Mailchimp, click your profile icon and go to Account → Extras → API keys, then create a key (you’ll only see the full key once, so copy it).
- Paste your API key into Carly on the integrations page.
- Describe the workflow in plain English, and Carly builds it — connecting Mailchimp to whatever else you need, on triggers, without your laptop open.
Frequently Asked Questions

Yes. Mailchimp’s directory includes 300-plus native integrations — Shopify, WooCommerce, Squarespace, Wix, Salesforce, HubSpot, Typeform, Jotform, Canva, WordPress, Instagram, Facebook, Stripe, Square, QuickBooks, and Xero among them — plus Zapier and Make for no-code automation and a public Marketing API (v3.0) for custom connections.

How do I connect Mailchimp to an app that isn’t listed?
Use Mailchimp’s Marketing API. Generate an API key under Account → Extras → API keys, then hand it to a platform that supports bring-your-own-API-key connections — Carly does this and can wire Mailchimp to any tool with an API.
How much does an AI automation for Mailchimp cost?
Carly’s AI agents start at $35/month, with non-AI workflow steps running free and unlimited. Your Mailchimp plan and API access are separate.

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."
