Move the platform without losing the inbox.

We plan the architecture, data, authentication, suppression, warming and cutover so a platform change does not reset years of sender trust.

The work

What Optinize handles.

Define streams, subdomains, IP allocation, provider requirements, data and rollback paths.

Move engaged traffic first, preserve suppressions and prevent duplicate or unauthenticated sends.

Monitor placement, blocks, complaints and business-critical flows until the new setup is stable.

Best fit

Share the domain, platform and symptom. We will tell you what we can verify, what remains uncertain and the next sensible step.
