Postmark App has been very effective for our platform. Very little gets flagged and they have an easy way for users to "appeal" and have their emails approved. The only thing (good and bad) is that if a vendor erroneously flags our emails to our provider team as spam, Postmark won't event attempt to deliver it. It's a hard no. So, we have to have an email sent from that address to Postmark to (in essence) re-subscribe /verify that they want the emails to come through. This happens even though people aren't manually flagging them as spam, it's something on Y!, Gmail, Hotmail, etc. are doing on the back end.
