I work for an ESP who provides email forwarding, storage, and as a seperate
service, email marketing and mailing lists.
We use Postfix; as other commenters have said, it's a (very good) delivery
mechanism. But: It doesn't generate messages, just ensures they get where
Working with Postfix as a delivery platform is very pleasant. It's easy to
configure, extremely stable, well-documented, the code is super clean, and
wrapping your application around it is quite easy.
Our mailing list software is developed in-house. We used to use mailman (almost
a decade ago?), but it's very limited for email marketing purposes.
Some general suggestions:
Keep your streams clear: Never mix IPs sending misc non-bulk mail with IPs
sending bulk mail. This does not mean snowshoe, but you don't want your CEO's
mail getting bounced to his best buddy at gmail because gmail now hates your
PTRs are important.
Sign up for every FBL you can. Track bounces. Never resub someone who has
unsubscribed from your lists.
SPF and DKIM matter to varying degrees.
Some MXes you deliver to will want to be coddled (specific delivery settings).
IP reputation is key. You have to grow it. Blasting Yahoo with 200k messages in
5 minutes is going to cause headaches for everyone involved.
If you end up on a blacklist, treat the operators with respect. Giving them
crap is not going to help anyone.
Engaging in scummy behavior for a short-term win is going to screw you
long-term. Your marketing dept may not understand that; you'll have to stand
firm with them. Do no let them buy email address lists.
Delivering email, especially for marketing purposes, is very complex. If it
isn't your core competency I would suggest outsourcing it to a dedicated ESP.
