Hi Dominique 
Do you know if those 3rd party services such as aweber and mailermailer support an existing list of people that have already subscribed to our newsletter?

I use mailermailer and you don’t worry about spam reports, they handle things very well, including optins, double optins, whatever you want.
I am irregular about sending it though, I need to buckle down and get more regular.
