Serendipity35

Although Gmail doesn't offer traditional email aliases, you can easily use a kind of alias (alternate) email with your existing account. This is useful for sorting and directing messages.

For example, let's say I own the email serendipity@gmail.com but I want to use it with students in one of my courses. I don't want that course-related mail mixed in with the rest of the messages, so I tell students to email me at serendipity+353@gmail.com (352 being the course number, but I could have added media or any other characters). I will receive those messages sent in my regular mail and then I will set up filters in Gmail to automatically direct these messages to a folder for the course. I could also apply a label or star them, skip the inbox, or forward them to another email account or any other options offered in Gmail. It's a nice way to stay organized. For a small business, you could use aliases for different inquiries by adding +info, +estimate, +billing or any useful label to customize the message.
