If you were using Hostinger Email and purchased a Google Workspace email service, you can migrate the content of your previous mailboxes by accessing your Workspace webmail.
Once there, click on the top right Settings icon ⚙️ and select See all settings. Next, go to the Accounts and Import tab, locate the Import mail and contacts section, and click on Import mail and contacts:
In the pop-up window, enter the following information:
The email address you want to import from. For example,
The password for your previous email address
Click on Continue to select the desired import options, and when all is good to go, click on Start import
Once the import process is completed, all your messages will be available in your new Google Workspace email account.
