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.
- Set up your email address and/or domain
- Transfer your mailbox contents
- Transfer your contacts
- Transfer your calendars

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:
- 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 (
.vcffiles) for the best compatibility, otherwise comma separated values (
.csvfiles) will also work.
- 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:
- Export calendar events from your old account.
- Import these calendar events into your Fastmail calendar.
See our calendar migration guide for detailed information.

Configure your mobile devices
Configure your mobile devices to use Fastmail on the go.
- The official Fastmail app is the best way to use Fastmail on your iPhone, iPad, or Android device.
- We also have instructions on configuring popular desktop clients if you want access to Fastmail in addition to our web interface..
Announce new email address
If you have changed your email address (not applicable if you use your own domain), then be sure to notify everyone in your contact list of your new address.
- Go to Contacts
- Select all contacts
- Compose to
- Cut 'to' list and insert into 'bcc' field (This is important to ensure that individual email addresses are not shared to everyone.)
- Write to all informing them of your new address.
Forward mail from old account
Set up forwarding/importing and leave them in place for some time (not applicable if you use your own domain).
- New mail will still arrive into your old account (either people who didn't read your email above, or newsletter subscriptions that you haven't updated yet). Use a fetch identity or set up a forward at your old account to send any new mail to your account at Fastmail.
- You may wish to set up a vacation autoreply on your old account to send information back to anyone who mails you of your new details.
Update old subscriptions
- Save a custom search (looking for all mail at your old email address) in Fastmail so you can easily see what mail is still coming to the old address.
- You may wish to monitor your Inbox for mailing list subscriptions that need to be updated. Set up a search for:
header: "List-unsubscribe: <" header:"X-delivered to: <old email address>"
- Save this query so you can run it again periodically to check for any list mail being sent to your old address.
- You'll need to manually change your subscriptions: Fastmail can't change your subscription automatically for you unfortunately!
