I have been in to email marketing from a very long period and have tried almost all solutions out there. This is by far the best solution that I have experience at such small price – I couldn’t find any issues however over the period, I have suggested few adjustments and the developers have been kind enough to respond quickly and make changes. This is a wonderful tool for beginners to medium scale marketing, I have thoroughly experienced it using Exim & Postfix and really loved what they’ve done.
