Comprehensive Guide to Email Deliverability

Pardon my French, but I don't give a flying fuck about how deliverable someone's "campaigns" written by their "creatives" are to the "clients" on their "targeted lists".

I want to know how I, a human being running a mailserver, can consistently ensure that other email users -- most notably Gmail users -- can consistently receive and read the _individual_ emails I send, at a rate of _maybe_ half a dozen on a busy day.

As far as I can tell (admittedly largely from the stories of others, as I have basically given up on this myself at this point), there are lots of guides to deliverability of email marketing campaigns, and Google will work with marketers to ensure that their email gets delivered, but for a small non-commercial mailserver without a full-time staff it's not really practical to expect reliable delivery. Which seems sad and backwards to me.
