For instance, you can make your Gmail address appear different if you sign up for a mailing list by using email@example.com, firstname.lastname@example.org, or email@example.com instead of firstname.lastname@example.org. No matter how many dots you use or where you put them, Gmail will still deliver those messages to your primary inbox.
The second way to change your email address but still have the emails come to your primary inbox is by using the plus sign. You can insert a plus sign with a combination of words in your email address.
For example, whenever you sign up for a newsletter, you could use email@example.com. Gmail will not look at what comes after the plus sign in the address so that the emails will come straight your inbox. However, you will still see those messages addressed with the +newsletters part, making them easy to spot.
