I'm running a membership site using Amember and Wordpress as a CMS. I'm thinking about integrating ListMailPro as a server side solution for email lists. However, I've been reading a lot about deliverability issues with running email programs on your own server. Does anyone know how big an issue deliverability is with ListMailPro and other server side email programs? It seems that running ListMailPro on a dedicated server would take care of some of the deliverability issues. But that's a little more costly than the monthly aweber fee. $19/month aweber versus close to $100 for a dedicated server. The drawback to Aweber is it doesn't fully integrate into Amember the way that ListMailPro does. Any thoughts from people who are using or have used these solutions?
