I've got 2 email lists. One which is a Buyers list of 20,000. 1/3 of that list are non-optins. I also have another list of 220,000 which are all single optin (but not a Buyer list). I'm using Interspire Email Marketing software but need an SMTP server to email out through. Can anyone recommend a fast, relatively low cost solution so i can keep mailing out. Thanks.
