Cross sells in the confirmation email? Idiot idea. "Thanks for buying this Membership - now but THIS, THIS and THIS, too (cuase I'm a greedy, desperate FUCK).
FAIL.
Now: Doing everything you suggested BUT the cross-sells should be done, yes.
(And the way "email marketing" works is you send that first confirmation email, then a follow-up email asking if everything is going okay with their new membership a day or two after the first, then three days later you hit them with a third (and final) email, saying "Glad you're liking your new Membership to xyz; now check out these other products."
You've built trust, no go in for the kill; do it "right away" with that initial confirmation email and A. they won't see it, B. they won't 'get it", C. they wanna wank it NOW to what they just joined and D. You come across as a shady fuck.
But everything else BESIDES the cross-sells is good advice.
