Hmm [goes off and does more research].
Okay, it appears this is so common that gmail has some guidelines that if people follow they are are usually okay:

It does look like namecheap filters spam aggressively so possibly that helps.
In general be careful for the reasons I mention. But it looks like if you follow the guidelines with gmail then you'll be good.
Sorry for the inaccurate information.
I have namecheap forward all of my email from *@my-domain-name.com to [email protected]. Works no problem, has for several years. Prepared for the eventual switch to FastMail when they support multi-label messages.
The only messages that end up in my spam folder are spam for knock off online pharmacies.
