I have an established eCommerce website with a few years trade under its belt which I would like to send marketing emails for. The customers on our list have all explicitly agreed to receive such offers and can be exported with ease from our database. I am looking for any recommendations with regards to a platform I could use to send the emails from. I am a fairly competent designer and programming so generating the emails and web versions is no problem at all. I just really need to find a company who I can use to send the emails and track open rates and conversions from.
Any help would be very much appreciated.
