That reminds me, I recently registered to Experian only to find out ".dev" emails are considered invalid. I had to register an email on one of my ".com" domains then forward over to even register with them. I called up support and they found it confusing as well, but hey ho - I can't even raise a ticket.

this is what i keep telling my friends who get .dev .io .ninja or whatever. Spam filters don't care how fun and quirky your domain is. Neither do boomers they won't recognize it as a domain either. Just get the damn .com

Whilst I agree people should at least have a ".com" backup domain (at least for email use), many services are supporting the less common TLDs nowadays. In particular, ".dev" seems to be supported well in my experience (where Experian has been the only problematic service).

As for the spam filters, whilst the domain definitely does play a part in some cases - there's more to it than that. Having the correct security configuration (DKIM, etc.) and a "trusted" mail server (good luck asking M$ for their list, though) goes a long way.
