My Slate email address is email@example.com. If you email firstname.lastname@example.org, your message will bounce. There is no email@example.com.
If there were, though, it’s a good bet that he’d get a lot of messages that were intended for me (poor guy). For just that reason, Google decided to do things differently from other email providers when it launched Gmail. Namely, it decided to ignore periods in its users’ email addresses altogether. That’s right – they make absolutely no difference. As a post on Google’s help forums clearly explains:
firstname.lastname@example.org = email@example.com
firstname.lastname@example.org = HOMERJSIMPSON@gmail.com
email@example.com = Homer.J.Simpson@gmail.com
You could even email firstname.lastname@example.org, and your message would still make its way to the very same doughnut-loving dude.
This is not new – it’s been this way for years, and I’m sure a lot of people reading this realized it long ago. But the funny thing is how many people haven’t – and I’m embarrassed to admit that I was among them until my colleague Josh Levin blew my mind with this factoid recently.
All these years I’ve been making a point of pronouncing the “dot” whenever I tell people my gmail address, when in fact I could have just as easily remained dotless. For that matter, I could start telling people that I’m will.or.emus and leaving them to wonder whether I share my account with a flock of flightless birds.
That got me wondering: In which other domains are the dots superfluous, and in which do they make a crucial difference? And how do different companies decide which standard to observe?
For some reason, none of the companies I contacted were eager to discuss their policies or rationale with regard to dots in user names, either because they considered my query unworthy of a response, or because they’ve never really given it a lot of thought themselves. Left to my own devices, I experimented a bit and arrived at the following tentative taxonomy:
• Dots matter: Microsoft Outlook, Yahoo Mail, Apple iCloud
• Dots don’t matter: Gmail, Facebook
• Dots strictly prohibited: Twitter
