Same here. I have a .dev tld (Ooh ahh very fancy). My email is [first]@[last].dev . The amount of times they go "@ gmail?" Is astonishing. These are people who all day, countless times per day, for countless years, are collecting emails (front desk clerks, support reps, whatever), and not one email in the history of emails is the format blah@blah.blah@gmail.com, but somehow they think mine is. Should've just stuck with the Gmail
I've had firstname@lastname.me for a few years now and so far haven't had any confusion. They just read it back to me to make sure it's correct. I used to do the businesname@mydomain and that caused lots of confusion, especially when support ask me for my email and I can't remember what it was. And they are confused because my email has their name in it.
Mine is me@[fullname].[tld] and I still kind of regret it because no one expects such a short set of characters before the @ sign. Even many websites don't. It's never been rejected but rather it breaks basic personal details masking. Because they often mask an email address replacing all but the first and last characters of the username portion with asterisks and leaving the domain fully exposed...
Not to mention that I've been told by a couple people that they find it to be an awkward email address. Sending to "me" from their perspective should mean sending to themselves.
Hmmm I've had websites not accept mine but I'm still not sure why. Maybe it's the .dev . Cheapo regex
I wouldn't be surprised. They probably have like .com, .net, .org, .gov, .edu and maybe some ccTLDs hardcoded.
