Switch from Google Workspace to mailbox.org: step by step

How to move your mail, contacts and address from Google Workspace to mailbox.org without losing anything. Most moves take an evening to set up, then a few weeks of forwarding.

Show me the stepsCompare them side by side

1. Before you start

   • Check where your address lives. Google Workspace runs on your own domain, like you@yourname.co.uk, so your address comes with you: you'll change a few DNS settings.
   • Check the space you need. See how much mail you have in Google Workspace, and compare it with mailbox.org's plans (the cheapest is Standard, €3 a month, yearly (from summer 2026), with 20 GB).
   • Read the small print. mailbox.org's page covers exporting, cancelling and refunds under "Before you sign up".

2. Open your mailbox.org account

   Sign up on mailbox.org's website (30 days free), and turn on two-step sign-in straight away. You'll find the link on mailbox.org's page: mailbox.org.

3. Bring your mail across

   Copy it with a mail app. Add both accounts to a mail app over IMAP (Thunderbird is free, for Windows, Mac and Linux), then drag your folders from Google Workspace to mailbox.org. It's slow for a big mailbox, but it works with almost any provider. Thunderbird ↗

   Your old mail stays where it is while it's copied, so nothing is lost if you need to start again.

4. Move your contacts and calendar

   Export your contacts as a .vcf file and each calendar as an .ics file from Google Workspace, then import them into mailbox.org. Most providers have both options in their contacts and calendar settings.

5. If you use your own domain

   Your address moves with you. Do this after your mail has been copied:

   1. Add your domain in mailbox.org's settings, and create the same addresses there.
   2. A day before, lower the TTL on your domain's MX records (to 300 seconds, say), so the change takes effect quickly.
   3. Replace the MX records with mailbox.org's, and swap Google Workspace's entry in your SPF record for mailbox.org's.
   4. Add mailbox.org's DKIM record, and keep your DMARC record.
   5. Check the result with a free DNS checker before you rely on it.

6. Check everything arrived

   • Compare the number of emails in each folder on both sides.
   • Send a test email to your new address from another account, and reply to it.
   • Check that mail forwarded from Google Workspace is arriving, and isn't going to spam.

7. Close Google Workspace, when you're ready

   Wait at least a month, until nothing new arrives there. On a free account you can leave it open with forwarding on instead. Before you close a paid account, download a last copy of your mail.

   • Cancelling: An admin cancels the subscription in the Google Admin console. If you bought through a reseller, cancel with them.
   • Refunds: Cancelling an Annual/Fixed-Term Plan early still charges the rest of the contract. On the Flexible Plan, charges stop when you cancel.
