First off, let me say that the small number of emails we send out are not spam. We include removal links and the emails are generally centered around free webinars that our marketing department hosts.
The problem I've had in the past is being put on an RBL list. How it happened previously was a few hotmail recipients must have marked the email as spam. After Microsoft marks you as a spammer the RBL's are soon to follow. It has only happened that one time but once was most certainly enough. So, I'm looking for recommendations for an external email marketing service. Things to take in to consideration are cost, features/reports, and reputation. iContact would be an example, although I have never used that service personally.
Is this solution one that many of you have tried? It's just that I don't want any disruption to company emails, ever. These marketing emails are just too risky.
