How do you use your @facebook.com address? Just like you would use an email address, basically. If someone wants to chat with you via Facebook Messenger but can't access Facebook for some reason (like, say, if your workplace blocks Facebook.com), he or she can email your Facebook address, and the email will show up in your Facebook message box. When you respond to that Facebook message, it will show up as a new email in that person's email inbox. He or she can respond to it, and it will show up as a Facebook message for you -- and so on and so forth, unto infinity. You can also send new emails to people from the Facebook messages page, by typing in any email address in the "To" field when you start a new message. That email will appear as coming from your @facebook.com address.20 Years Of Free JournalismYour Support Fuels Our MissionYour Support Fuels Our MissionFor two decades, HuffPost has been fearless, unflinching, and relentless in pursuit of the truth. to keep us around for the next 20 — we can't do this without you.We remain committed to providing you with the unflinching, fact-based journalism everyone deserves.Thank you again for your support along the way.
