# Migrate to Oveyon — SendGrid, Postmark, Mailgun, Amazon SES, Brevo or SMTP

> One page per source provider. SendGrid and Postmark have a ready, read-only import — suppressions, domains and webhooks, nothing switched off at the source; for the others, the manual path with what already exists. Cutover is per domain, with a way back.

Migrate

## Switch providers, with a _way back_.

From SendGrid and Postmark, suppressions, domains and webhooks come in by reading — nothing is switched off at the source, and the key you paste is not kept. From anywhere else, the path is short and written down here. The cutover is yours, domain by domain, and it undoes.

01 · The three rules

### What holds for any source.

#### Everything is read-and-copy.

Every call the import makes to the old provider is a GET, from a catalog frozen in code — a write does not exist, not even by mistake. What you brought is never deleted on the way back.

#### Nothing is switched off at the source.

The import redirects no traffic. Your application is what swaps host and credential, domain by domain; the old provider keeps accepting until you turn it off there.

#### The key you paste is not kept.

It never touches our database: it is kept encrypted, outside it, and deleted when the import ends — or it disappears on its own after hours without progress. The date we deleted it is written in the report.
