Migration
onmeil.eu moves your email, contacts and calendar from the major providers in one go. You sign in with your account at the old provider, choose what comes along, and let the process run in the background.
Migrating from Gmail — Turn on 2-step verification, create an app password, and paste it into onmeil.eu. Email, contacts and calendar move together.
Migrating from Outlook / Microsoft 365 — Sign in with your Microsoft account and onmeil.eu copies everything over directly. No app password needed.
Migrating from another IMAP server — For Yahoo, ProtonMail, Fastmail and every other IMAP provider. You enter the server details plus your username and password.
Tips
You can run the migration while you keep using onmeil.eu — it happens in the background.
