To transfer emails from one Gmail account to another, you can either do it manually or use an automated tool. In the manual method, you need to enable IMAP in your old Gmail account, then go to your new Gmail account’s settings, choose “Accounts and Import,” and add the old Gmail account to import emails. This process may take time if you have a large number of emails. For a quicker and easier solution, you can use an automated Advik Gmail Backup Tool that allows you to transfer all your emails, including attachments, in just a few clicks. It’s simple, fast, and ideal for large or multiple mailbox migrations.
