Hi guys, I have a sales letter that I want to send to my "non-opt-in" list. It's composed in HTML. I tried SendBlaster, only to find out my internet provider blocks post 25 permanently and therefore I can't use SB. So then I tried Mailchimp but it adds markup as if it's a opt-in mailing list (also adds address). Tried Mailjet and they reject my application for some reason. Before I try more, do you guys have any good recommendations on how I can accomplish this? I just want my HTML sent, no additional text crap from the service provider.
