A. Preliminary Remarks
Recently I have been looking into autoresponder- and newsletter tools. There is a plethora of possibilities to experience and compare. I will try and give a short overview. My own research lasted for a week or so, and at some point I just more or less stopped and signed up with a service I liked. So my article is not exhausting.
Yet, maybe a brief introduction may be of service, both to me, if anyone ever asks me about it, and to my potential readers. Even if offers may change, I believe some principal considerations will still be of value even later in the future.
