INTEGRATION · MAILCHIMP

AntForms meets Mailchimp.

Subscribe every respondent to a Mailchimp audience automatically.

The AntForms Mailchimp integration adds respondents to a Mailchimp audience on every submission via native OAuth, with merge-field mapping, tagging, and GDPR-compliant opt-in handling.

What teams build with Mailchimp

Three patterns AntForms customers ship most often, each reachable from the Integrations tab in under two minutes.

Newsletter signup forms

Every submission subscribes the respondent to your chosen audience, with their name and any custom fields mapped automatically.

Segmented email campaigns

Tag respondents dynamically based on their form answers - like which product they’re interested in - to trigger targeted Mailchimp automations.

GDPR-compliant opt-in capture

Use double opt-in and marketing-permission mapping (Pro) so consent is recorded the way Mailchimp and GDPR expect.

02 · SETUP · 2 MINUTES

Live in 2 minutes.

A few steps, under a few minutes. No code, no Zapier in the middle.

Apply static or dynamic tags, map interest groups, and configure double opt-in or marketing-permission fields.
05
Submit a test response

THAT’S IT · MAILCHIMP IS LIVE

03 · WHAT’S INCLUDED

Everything in the Mailchimp integration is free.

Every capability ships on the free plan: no paywalls, no metered calls, no per-seat markup.

Audience and list picker with live member counts
Merge-field, tag, interest-group, and marketing-permission mapping (advanced mapping is Pro)
Double opt-in support for GDPR-conscious signup flows PRO

Up to 3 Mailchimp connections per form on Pro

04 · HONEST LIMITS

The boundaries, named.

What the Mailchimp integration does not include, so you can plan around limits before they surface mid-rollout.

Free plan maps only email, first name, and last name; tags, interest groups, GDPR marketing-permission mapping, and double opt-in require Pro.
Up to 1 Mailchimp connection per form on Free, 3 on Pro.
Deliveries stop retrying after 5 attempts; 3 consecutive authorization failures auto-disable the connection and require reconnecting.
Respondents who are unsubscribed, bounced, or have submitted a Mailchimp “forget me” request won't be re-subscribed by a new submission - the connection surfaces this as a compliance-state error instead of retrying indefinitely.

AntForms retries up to 5 times with exponential backoff, honoring Mailchimp's rate limits. After 3 consecutive authorization failures, the connection auto-disables and needs reconnecting.
