Live

In short

Fluxo Flow connects to Mailchimp with an API key or credentials you provide; workflows can add or update a subscriber, find a subscriber and add or remove tags and more, and start from new subscriber. The integration is live.

Live means tested end to end against real accounts. Found a problem? Tell us.

What you can do

Actions and triggers for Mailchimp.

Actions

  • Add or update a subscriber

    Adds a person to an audience, or updates them if they're already in it. New people get the status you choose: “Pending” sends Mailchimp's opt-in confirmation email.

  • Find a subscriber

    Looks up a person in an audience by email.

  • Add or remove tags

    Adds tags to (or removes them from) a person in an audience. Tags that don't exist yet are created.

  • Add a subscriber to a segment

    Adds a person who is already in the audience to a static segment.

  • List campaigns

    Lists campaigns, newest first, optionally only sent ones or one audience's.

Triggers

  • New subscriber (checked on your plan's schedule interval)

    Starts a run for each person who becomes subscribed to an audience (after confirming, on double opt-in audiences).

FAQ

Mailchimp questions, answered.

Will people get a confirmation email?

Only if you choose “Pending” for new people (the default): Mailchimp then emails them to confirm before they're subscribed. Choose “Subscribed” only when you already have their consent.

Why did my connection stop working after a year?

Mailchimp API keys created since June 22, 2026 expire one year after they're made. Create a new key and update the connection.

What access does the key give?

Mailchimp keys have full access to the account; Mailchimp has no read-only or limited keys. Keys act as the user who created them.

Is the Mailchimp integration ready to use?

Yes. Mailchimp is live: connect it in Settings → Integrations on any plan, including Free (on Free you can build with it and Dry Run; running it live needs a paid plan).

Can I call Mailchimp endpoints the integration doesn't cover?

Yes, if Mailchimp has an API: save a key in the encrypted credential vault and call it with an HTTP Request step.

Can I test a workflow without touching my real data?

Yes. Dry Run walks through every step with simulated app calls, so nothing is sent until you run it for real or activate its trigger.
