How these shady registry handle abuse is why i never use their dirt cheap tld for email. Most corporate firewall either outright reject them or blackhole into oblivion. Best case scenario is auto route to spam folder.

Might be useable as cheap domain used for hobby site, as personal dynamic dns domain but for email, nope.

I'd cough up $10 for .com .net .org and recent popular one the .me .io for best email deliverability instead of saving $5 and wondering whether my outgoing mail would arrive or not.
