Switch from Zoho Mail to Fastmail: step by step

How to move your mail, contacts and address from Zoho Mail to Fastmail 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. If it ends in @zohomail.com, it belongs to Zoho Mail and stays there: you'll forward your mail and tell people your new address. If it's on your own domain, like you@yourname.co.uk, it comes with you: you'll change a few DNS settings.
   • Check the space you need. See how much mail you have in Zoho Mail, and compare it with Fastmail's plans (the cheapest is Individual, $5 a month, yearly, with 50 GB).
   • Read the small print. Fastmail's page covers exporting, cancelling and refunds under "Before you sign up".

2. Open your Fastmail account

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

3. Bring your mail across

   Use Fastmail's importer. Fastmail's importer copies mail, contacts and calendars from most providers. Open Settings, then Migration, then Import. It also takes .mbox and .eml files. Fastmail's guide ↗

   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 Zoho Mail, then import them into Fastmail. Most providers have both options in their contacts and calendar settings.

5. Keep your @zohomail.com address working

   1. Forward new mail. Look in Zoho Mail's settings for automatic forwarding, and add your new address.
   2. Tell people. Send your new address to the people who matter, and add it to your email signature.
   3. Update your sign-ins. Change the email address on your bank, shopping, social and work accounts. A password manager's list of saved sign-ins is the quickest checklist.
   4. Keep the old account open for a while. Mail will keep arriving there for months. Sign in now and then so it isn't closed for not being used.

6. If you use your own domain

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

   1. Add your domain in Fastmail'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 Fastmail's, and swap Zoho Mail's entry in your SPF record for Fastmail's.
   4. Add Fastmail's DKIM record, and keep your DMARC record.
   5. Check the result with a free DNS checker before you rely on it.

7. 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 Zoho Mail is arriving, and isn't going to spam.

8. Close Zoho Mail, 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: Downgrade to the free plan, or tell Zoho you don't want to renew, before the period ends.
   • Refunds: A pro-rata refund of prepaid fees only if you close your account because Zoho broke the agreement.
   • Renewal: Renews automatically at the end of each period, charged to the card you last used.
