Migrating from Mailchimp to MailSend
This guide outlines how to migrate your contacts, templates, domains, credentials, and webhooks from Mailchimp to MailSend smoothly.
Quick Answer
Migrating from Mailchimp to MailSend involves exporting list databases and suppressions, updating DNS verification keys (SPF, DKIM, DMARC), and replacing API endpoints or REST API credentials. Most teams complete cutovers in under 2 hours.
1. What to Export
Export your audience contact lists as CSV files from the Mailchimp Audience portal. Retrieve your campaign layouts by copying raw HTML designs from the template editor.
