Switch from Google Workspace to Runbox: step by step

How to move your mail, contacts and address from Google Workspace to Runbox 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 Runbox's plans (the cheapest is Mini, $34.95 a year, with 10 GB).
   • Read the small print. Runbox's page covers exporting, cancelling and refunds under "Before you sign up".

2. Open your Runbox account

   Sign up on Runbox's website (30 days free, then a 60-day refund), and turn on two-step sign-in straight away. You'll find the link on Runbox's page: Runbox.

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 Runbox. 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 Runbox. 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 Runbox'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 Runbox's, and swap Google Workspace's entry in your SPF record for Runbox's.
   4. Add Runbox'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.
