Pro tips
- Begin warming up your sending domain on the new ESP while still operating on your current platform to establish sender reputation before full migration.
- Create a visual “data dictionary” that maps all custom fields between platforms to ensure no customer information is lost or misinterpreted during transfer.
- Prioritize high-value automation workflows (like abandoned cart and welcome series) early in your migration schedule to minimize revenue impact.
- Consider migrating during a historically lower-volume period for your brand to reduce risk; avoid peak seasons like Black Friday/Cyber Monday or your specific high-volume periods.
