I have a huge number of email list. These are users who signed up for accounts and decided into a mailing list on my website and I want sending a regular newsletter. So I attempted delivering it out with my host server, but I got a notice stating that if I did it again they would kick me off the server. Are there any excellent business that are created for this kind of stuff? I have to find a business that will support this and show me some sort of report about how many emails get opened, erased, opened then deleted, etc. Any referrals please? Thanks!
