Setting up GOOGLE / GMAIL Email Accounts

Before using Postbox, Enable Access at Google

Enable IMAP – Google requires that you enable IMAP access before third party apps like Postbox can work with your account.

  • In your browser, login to your Web Gmail account.
  • Click the gear button in the upper right-hand corner and select Settings.
  • Click the Forwarding and POP/IMAP tab.
  • In the IMAP Access area, make sure Enable IMAP is selected.
  • Click the Save Changes button.

Enable Folders – Next, enable access to the folders you wish to see in Postbox:

  • In your browser, login to your Web Gmail account, navigate Settings > Labels Tab.
  • For each label that you wish to see in Postbox, select the Show in IMAP checkbox.
  • Then in Postbox, go to the File menu > Subscribe. Select your Gmail account in the pull-down menu, and subscribe to each folder you wish to see.

Once complete, continue setting up your account within Postbox.
