Switching email marketing providers, whether prompted by outgrowing a simpler tool or seeking better automation depth, requires a deliberate migration plan to avoid data loss, automation gaps or deliverability disruption.
The riskiest moment in any provider migration is the gap between turning off the old automation and confirming the new one works correctly — a brief parallel-run period exists specifically to eliminate that gap.
A sudden shift in sending volume and pattern to a new provider can temporarily affect deliverability, making a gradual ramp-up of sending volume on the new platform, rather than an immediate full-volume switch, a sensible precaution.
This varies by complexity, but a few weeks is often reasonable to verify automation, deliverability and reporting all function correctly before fully decommissioning the old platform.
See our pre-switching checklist for a detailed list of items to verify before committing to a specific new provider.
Generally yes, for a straightforward data export and import, but verifying consent records transferred correctly and remain compliant is an important post-migration check.

Plan for a parallel-run period where both the old and new provider remain active briefly during migration — this avoids gaps in automated communication and lets you verify the new setup works correctly before fully cutting over.
