I am using Google Apps Engine (GAE) for a small project. I need to send a bulk announcement email (1000 users) to everyone that has registered on the site. The announcement has certain customizations for each user. I have found that the mailer built into GAE doesn't make it through most spam filters. Anyone have any suggestions on how I might be able to get around this issue?
Since GAE cannot open sockets except to fetch web pages on port 80 and 443, I started using postmarkapp.com to send confirmation emails. However, they have restrictions against bulk email and only allow transactional email. I tried sending a bulk email, but they detected it pretty quickly and shut it down.
