I've never had any major problems with a gTLD and email but I have had colleagues have spam filtering issues. I have used a .io domain and I haven't had a problem, although we don't email too frequently. I must say it is somewhat fashionable with startups now to get gTLDs or cute ccTLD. However, there is an ethical issue with io specifically. [1]

As for my own personal opinion, I'm getting far more used to seeing startups and other services on TLDs other than .com. I think consumers are getting used to it now as well, in fact a lot of clients I work with won't even type the address into the browser anymore. They navigate to it via Google. Also, if you need to change TLDs at some point there are plenty of successful companies that have done so. [2]

Namecheap, it's great. I like using it. I also use Google Domains which is surprisingly nice.
