Migrate from Mailchimp to GetResponse without breaking sends
The right order to move lists, keep automations firing and preserve deliverability.
- Export segmented lists and tags from Mailchimp as CSVs.
- Import into GetResponse with matching custom fields and tag mapping.
- Recreate the top three automations first — welcome, abandoned browse and re-engagement.
- Warm up sending with your smallest engaged segment for the first week.
- Cut over MX/DKIM/DMARC records only after the warm-up window succeeds.
