One of the nice features of reading mail via POP 3 in Gmail is how it can automatically tag the emails with any tag of your choice. For example, you could create a tag for each email account you read. Then, you could select one of these labels to view only that mailbox’s emails.
The way it’s implemented in POP3 is very robust. Even if your name is not listed in any of the to fields (e.g. like in a BCC message), it will still tag the message correctly.
One of the drawbacks of using POP3 is that it can sometimes take up to an hour before it reads your mailbox. One solution for this is to use forwarding instead of POP3 which will deliver the emails as they arrive. However, if you switch to forwarding, you won’t have the correct tagging capabilities of POP3. In this post, I will show you how you can combine the two methods and get the best of both worlds.
