I have a list of potential people I would like to send emails to (for an offer). The thing is, I would like to track opens, deletes, etc. to see if the "campaign" is successful - or - if it needs to be tweaked. The only way I heard that this could be done is by using an Autoresponder.
I feel that the people really do need my service but at the same time, I became aware of their existence through a third party.
So, if you want to contact a group of people through email (and use of the auto responder is frowned upon), where can you email from?
