# Mailchimp (/integrations/mailchimp)





{/* MANUAL-CONTENT-START:intro */}

Use [Mailchimp](https://mailchimp.com/) in Sim to manage audiences and members, campaigns, automations, templates, segments, tags, and reports. The actions below also cover merge fields, interest categories, landing pages, signup forms, and batch operations.

## Member removal [#member-removal]

**Delete Member from Mailchimp Audience** calls Mailchimp's reversible archive endpoint. **Archive Member from Mailchimp Audience** instead targets permanent deletion of identifying data, after which the member cannot be re-imported. These UI labels differ from the provider's terminology.

The current permanent-deletion action sends `DELETE`, while [Mailchimp documents `POST` for delete-permanent](https://mailchimp.com/developer/marketing/api/lists/members/create-member-action-delete-permanent). Its compatibility is unverified; do not rely on it for deletion until the request method is corrected and tested.
