Migrate BTinternet Emails to G Suite

You want to migrate BTinternet emails to G Suite or Gmail but BT Mail has no export button and Gmail no longer pulls mail from other accounts so you cannot move BT mail to Gmail in old ways. Google ended POP fetching in January 2026 so old guides that use port 995 fail. Below are three ways to move BT mail to Gmail, BT settings you need and fixes for common errors.

Which BT Mail IMAP settings do you need?

Use your full BT address as username and mail.btinternet.com as host. BT's help page lists these values and every way to move BT mail to G Suite or Gmail needs them.

• Incoming IMAP: mail.btinternet.com, port 993, SSL enabled (BT recommends IMAP).
• Incoming POP3: mail.btinternet.com, port 995, SSL enabled. BT does not recommend it.
• Outgoing SMTP: mail.btinternet.com, port 465 (587 also works), SSL enabled, with sign in required.
• Password: your BT password. BT says not to enable secure password authentication.

BT also says older insecure connections will stop so your mail application must use SSL/TLS. See BT's server settings page and BT's securing your email client page. A BT community helper also noted that accounts without BT broadband or Premium Mail are webmail only so mail applications cannot reach them.

Can Gmail still add BTinternet emails with POP?

No. Google ended POP fetching and Gmailify from January 2026. Older guides tell you to open Gmail Settings, select Accounts and Import and add a mail account with mail.btinternet.com on port 995. That route cannot move BT mail to Gmail now.

Three options remain to move BT mail to Gmail: an IMAP mail application, Google's Data import for Workspace teams and software. Forwarding set up in BT Mail sends new messages only so old mail needs one of these three ways to move BT mail to G Suite.

How to migrate BTinternet emails to G Suite with an IMAP client?

Add both accounts to one mail application over IMAP, then copy folders from BT to Google. It can move BT mail to Gmail for free and suits a small mailbox. BT community members suggest that route and one says it works in Outlook 2010.

1. In Gmail or Google Account settings, enable IMAP. Create an app password if Google asks for one.
2. To move BT mail to Gmail, open Outlook or Thunderbird and add your BT account over IMAP with mail.btinternet.com, port 993 and SSL.
3. Add your Gmail or G Suite account to that application too, to move BT mail to Gmail between two logins.
4. Wait for BT folders to finish syncing. Open large folders once so full messages download.
5. In your Google account create a folder to store your BT mail.
6. Select messages in a BT folder, then drag a copy to your new Google folder to move BT mail to G Suite.
7. Open Gmail on web and check counts before you move BT mail to Gmail from another folder.

A BT community reply from April 2026 adds a tip for Inbox and Sent. Only folders you created can move straight across so create BTInbox and BTsent folders, drag Inbox and Sent mail into them, then move those two folders to Gmail. Menu names differ by version so test one small folder first. IMAP mirrors deletions so a message deleted in your mail application is deleted on BT too.

How to move BT mail to G Suite with Google Data import?

A Google Workspace super admin can move BT mail to G Suite over IMAP, which moves BTinternet emails to Gmail accounts inside your domain. It does not include personal @gmail.com accounts. Google calls G Suite Google Workspace now.

1. Enable IMAP in your BT account if your mail settings page shows a switch for it, then plan to move BT mail to G Suite per user.
2. In Admin console, open Data import and choose IMAP. Enter mail.btinternet.com and select Test connection.
3. Map users. For a few users, enter every BT address, BT password and Workspace address. For many, upload a CSV file under 128 MB.
4. Start your import and watch progress. Exit a finished import before you start another.

Google lists steps and limits in its guide to Migrating email from an IMAP account. One import includes up to 100 IMAP users and one BT address maps to one Workspace user.

Steps to move BT mail to Gmail with software

1. Install Corbett IMAP Migration Tool on your Windows PC and open it with Run as administrator to move BT mail to G Suite. Select Open.
2. Select Email Account, then Add Account.
3. Enter your BT address and password. It finds server and port itself or use mail.btinternet.com and port 993.
4. Select Add. Your BT folders appear in a tree, ready to move BT mail to Gmail.
5. Preview messages in four tabs: Content, Message Header, Properties and Hex View.
6. Set filters for date, subject, To address or content if you need less mail.
7. Select Export, then choose Gmail as target.
8. Enter your Gmail or G Suite sign in details to move BT mail to Gmail, then open your Google account and compare counts.

Lifetime licence starts at $99, with a 30-day money-back window. Its page lists contacts and calendars among items it moves so test them on your demo first. To retain a file copy before you move, see how to Backup BTinternet emails on computer. To move mail to a desktop application instead, see how to Export BTinternet emails to Thunderbird.

Which way to move BT mail suits you?

For one small mailbox, use an IMAP client to move BT mail to Gmail. For a Workspace team, use Data import. To move BT mail to G Suite with filters, use software.

Why does the BT move to Gmail fail?

Google cannot connect Gmail

A BT community user in February 2025 had valid sign in details yet Google could not connect when they tried to import BT folders and contacts into Gmail. Replies said accounts without BT broadband or Premium Mail are webmail only and another member suggested adding both accounts to one mail application and dragging folders across. No Gmail side fix was confirmed.

Sending fails with error 530

BT says to enable "My server requires authentication" in your mail application. Without it you get a 530 error when you send.

Password is rejected

BT says to set secure password authentication to off and to use SSL, since SPA will not work with it. Check your BT password at bt.com/mail first.

Inbox and Sent will not drag across

Use BTInbox and BTsent folders from our IMAP client section. BT community members confirm only folders you created move straight across.

Folders look empty in Gmail

Wait for uploads to finish, then check Gmail on web. A mail application may show folders before messages arrive. Compare counts folder by folder.

What to do after the move?

Retain your BT mailbox until counts match, then move BT mail to Gmail again for folders you missed. A community member says BT gives you a BT Mail address after you quit BT Broadband, with webmail access only. Tell contacts your new address and enable forwarding in BT Mail for new messages. Move contacts on their own, since mail moves do not always carry them.
