I have been using Acumbamail for a year. The support is very frustrating, as it doesn't translate easily to English. The Automation needs more options. I have to manually delete contacts every week or they won't get the automatic emails, which lessens the advantage of the automation. Nobody at support can help me set up a way to do this using an API; they act very uninterested in helping. It could be because I don't speak Spanish, but whatever the reason, I'm not very impressed.
