Never a day goes by when I don't use Google's fantastic emailing service. But did you know that you have access to many different addresses. If your email address is email@example.com, you could give someone the address of firstname.lastname@example.org. Oh my gosh! I know, try to dissipate the hysterics, because although this seems like a waste of your time you may be missing the point. Think about it - when you create websites with contact forms you may be inclined to include a clue in the subject line so you know when the email has come from you site. Well hows about using a new method, something like email@example.com so you know where it's coming from.You might want to set up some kind of alert when you get such emails through.
You could even use it to prioritize clients' messages to you. You give them the address of firstname.lastname@example.org so that you can respond to them faster! I'm always interested to find out about new and undiscovered features of Gmail, but I think this one is really rather interesting. What do you think?
