Migrate to Fastmail from another provider

If you're coming to Fastmail from another email provider (such as Gmail, Outlook, your ISP, or another cloud host), then you'll want to bring your email, calendars and contacts with you. You can also bring your own domain with you, keeping all your existing email addresses and aliases.

The following information makes it easy to move all your information into Fastmail, once you have chosen a plan.

  1. Set up your email address and/or domain
  2. Transfer your mailbox contents
  3. Transfer your contacts
  4. Transfer your calendars
  5. Making the most of Fastmail

We are building guides for large providers:

1. Set up your email address and/or domain

If you don't own your own domain, you'll need to select an email address at one of the Fastmail domains. You can still receive and send mail at your old address through Fastmail, providing you keep that account open.

If you have your own domain, follow our domain and email migration guide to learn how to transfer your domain, mail accounts, and aliases to Fastmail.

2. Transfer your existing mailbox contents

You can transfer your current mailbox into Fastmail using two methods: IMAP or POP.

Mail that is held on the server is accessed via IMAP and we recommend using this method. This allows you to make use of our backup services; and lets you access your mail from any of your devices or from any web browser.

Mail that has been downloaded to the desktop and lives within an application is accessed via POP. POP will only download mail from your Inbox; it won't download mail that is directed to other folders you have created.

Mail held on the server (IMAP)

You can import all your mail from your existing provider onto Fastmail. This is a one-time task to transfer all your mail, and may take some time to complete. Our email import tool works with any IMAP server, and we provide instructions for the most common providers.

Mail stored on the desktop (POP)

If your old mail isn't stored on an IMAP server because you have already downloaded it to your desktop using POP, you can leave it where it is, or you can transfer it to Fastmail's IMAP servers for access through the web client.

To transfer mail in your desktop client to Fastmail's servers, log onto Fastmail from your desktop client and drag the folders containing your existing mail into the Fastmail account's folders. Depending on how much mail you have, this can take some time before the mail completes uploading to our servers.

3. Transfer your contacts

Transferring your contacts into Fastmail can be done with the following steps:

  1. Export contacts from your old account. This can be done from your desktop mail client, or online if you have a web based provider. We recommend using vCard 3.0 (.vcf files) for the best compatibility, otherwise comma separated values (.csv files) will also work.
  2. Now you are ready to import your contacts into Fastmail

4. Transfer your calendars

Use the following steps to import your existing calendar into Fastmail:

  1. Export calendar events from your old account.
  2. Import these calendar events into your Fastmail calendar.

See our calendar migration guide for detailed information.
