If you use Namecheap for email domain(s) you may want to consider also splurging for their PremiumDNS to keep your domain(s) off spam blocks at other email providers.
I help maintain some emails at Gmail/Google Workspace but the domains themselves are at Namecheap. For a while there were complaints that some emails never landed in other people's inboxes... this led me to talk about the issue with one of the email provider recipients based in the UK & apparently they were null routing anything coming from Namecheap since they felt a lot of spam came from them. But after some experimenting I figured out their system (& probably others) were figuring out they were Namecheap domains via the default FreeDNS they use. On a hunch I switched those domains over to PremiumDNS and after that all our emails were landing in other inboxes correctly. I guess maybe it makes sense, a typical spammer buying a cheap domain at Namecheap isn't going to splurge for the higher end DNS service for it.
I'm not saying all email providers treat Namecheap domains as spam but just be warned there definitely ones out there that do.
