Migrate ISP Email to Gmail: Two Methods with Step-by-Step Guide

Your ISP gives you an email address as part of your internet package. When you change providers, close your account or simply want everything in one place, that ISP email history needs to go somewhere.

Gmail is the most common destination. This guide covers two ways to migrate ISP email to Gmail and when to use each one.

What Is ISP Email?

ISP (Internet Service Provider) email is an email account your internet provider gives you alongside your broadband subscription. Examples include accounts from Comcast, AT&T, BT, Vodafone and hundreds of regional providers.

These accounts use standard protocols. Incoming email is typically accessed via POP3 (older) or IMAP (newer). Outgoing mail uses SMTP. This means standard email tools can connect to them without any special integration.

One important note: most ISP email accounts are deactivated when you cancel your internet subscription. If you are changing ISP, back up your ISP email before the account closes. You usually have 30 to 60 days after cancellation.

Method 1: Gmail Mail Fetcher (Built-In POP3 Import)

Gmail has a built-in tool called Mail Fetcher that can retrieve emails from an external POP3 server. This is free and requires no additional software.

1. Log into Gmail and click the Settings gear icon, then See all settings.
2. Click the Accounts and Import tab.
3. Under Check mail from other accounts, click Add a mail account.
4. Enter your ISP email address and click Next.
5. Enter your ISP’s POP3 server address, port and password. Select Leave a copy of retrieved message on the server if you want to keep the original emails on the ISP server.
6. Click Add Account. Gmail begins fetching emails from your ISP account.

The limitations: POP3 import only works for ISPs that support POP3. It can be slow on large mailboxes, and Gmail may throttle the import rate. Folder structure from the ISP account is not preserved. All imported emails arrive in your Gmail inbox.

Method 2: Direct IMAP Migration with the Turgs Email Backup Wizard

For ISP accounts that support IMAP, or for migrating large mailboxes with folder structure preserved, the Turgs Email Backup Wizard connects to your ISP account via IMAP and transfers all emails directly to Gmail.

Step-by-Step: ISP Email to Gmail Migration

1. Launch the tool. Select IMAP Server from the email source list on the left panel.
2. Enter ISP credentials. Type your ISP email address, password, IMAP server hostname and port number. Most ISPs use port 993 with SSL/TLS. Check your ISP’s help documentation for the exact hostname.
3. Load folders. The tool connects to your ISP account and lists all your email folders. Select the folders you want to migrate to Gmail.
4. Select Gmail as destination. From the saving options, choose Gmail or G Suite.
5. Enter Gmail credentials. Type your Gmail address and password (or App Password if you have 2FA enabled).
6. Start migration. Click Backup. The tool transfers emails from your ISP account to Gmail. A live progress bar shows the status.
7. Verify. Once complete, open Gmail and check that your ISP emails arrived in the correct labels/folders.

ISP Email Migration via Configured Email Client

If your ISP email is already configured in a desktop email client (Outlook, Thunderbird, Outlook Express, Zimbra), you have another option. Instead of connecting directly to the ISP server, use the Turgs tool for that specific client to export its local email store and migrate to Gmail. This is useful when the ISP server is no longer accessible but you have a local copy of the emails in the client.

Related guides for specific client-based migrations to Gmail are available for Outlook, Thunderbird and Zimbra on the Turgs blog. See also the guide on migrating Google Workspace emails to Zoho for the reverse direction. And if you want to migrate ISP email to Office 365 instead of Gmail, see the Gmail to Office 365 migration guide for the same workflow applied to Microsoft’s platform.

Are you migrating from a POP3-only ISP account or does your ISP support IMAP?

Frequently Asked Questions

What is the easiest way to migrate ISP email to Gmail?

Gmail’s built-in Mail Fetcher (Settings then Accounts and Import then Check mail from other accounts) is the easiest option for small mailboxes on POP3-supporting ISPs. For large mailboxes or IMAP accounts with folder structure, use the Turgs Email Backup Wizard.

Can I migrate ISP email to Gmail if I already cancelled my ISP account?

Only if the ISP has not yet deactivated the email account. Most ISPs keep email active for 30 to 90 days after account cancellation. If the account is already deactivated, check if you have a local copy in an email client on your computer.

How do I find my ISP’s IMAP settings?

Search for “[Your ISP name] IMAP settings” or check your ISP’s support documentation. You need the IMAP server hostname (e.g., imap.yourISP.com), the port (usually 993) and whether SSL/TLS is required (yes in most cases).

Will my ISP email folders become Gmail labels?

Yes, when using the IMAP migration method with the Turgs tool. Each ISP email folder appears as a Gmail label with the same name. The Gmail Mail Fetcher (POP3 method) does not preserve folders.

How long does ISP to Gmail migration take?

The Gmail Mail Fetcher can take days for large mailboxes as Google throttles the import rate. The Turgs IMAP tool typically migrates a 5 GB ISP mailbox in 1 to 3 hours depending on your internet connection speed.

Do I need a Gmail App Password for the migration?

If your Gmail account has 2-step verification enabled, yes. Go to myaccount.google.com/apppasswords and generate an App Password for the migration tool. Use this 16-character password instead of your regular Gmail password in the tool.
