You have the .com? That's a no-brainer imo. I have a domain for a saas where the .com is squatted so I settled for .ai (and other surrounding TLDs / host permutations) and right out of the gate ran into some issues with firewall vendors in corpo environments.

Yeah, we have all of them. I saw it too where in bigger companies our emails were going straight to spam. Will migrate to it soon
