The period notation is really annoying for me. I signed up [email protected] when it was in beta and this "feature" wasn't publicized. Years later someone else was able to register [email protected] and now I get DoTerra order details and the like. I have no idea what I don't get at this point.
Don't know about a period notation feature. What does that do? And how do that not break email globally?
The same way that + doesn't break it. It is outside of the RFC altogether. So as long as wtf ever service you sign up for lets you type it, then you can do it.
As for what it does. Well [email protected] is a common thing. But someone that signs up to gmail with [email protected] can also receive email from email sent to [email protected] or even [email protected].
Google simply ignore all periods on the left of the @ for gmail based email addresses. Gmail only, not GSuite.
Wow, that's.... weird. I guess it works until they do something like the story above and screw it up.
