Tips

As most of you probably know Gmail is full of features that most people don't know.
One of this almost secret features is your email name formation. For Gmail, there are some characters that are not considered as additional information, so for example urbano.alvarez@gmail.com would be the same as urbanoalvarez@gmail.com (None of those email addresses are mine)
Another trick like that one is adding words at the end with a plus sign. For example urbanoalvarez+client1@gmail.com This way all emails sent to that addressed are received normally in urbanoalvarez@gmail.com

Taking this a set further we could create a folder in our inbox that I'll label "Client 1" for the example, and setup a filter that will send all emails addressed to "urbanoalvarez+client1@gmail.com" to the folder "Client 1"!
This way you can give separate email addresses over the Internet and have your email automatically sorted into folders.
You could even create a filter to send all emails addressed at "urbanoalvarez+trash@gmail.com" to the trash, and give that email when you are forced to signup in websites you know you'll never return...

There are tons of uses for this technique, and they'll save you a lot of time for sure
