Hi, I'm looking for a piece of software that will send out individual emails to a large amount of recipients. Preferably something that will allow me to import emails and names, use personalized fields (like firstname etc), and attach at least small files...and that has some feature to avoid screwing up the email server for sending too many at once (so maybe it sends X amount of emails each hour or something). Anyone heard of something like that? I have used Advanced Emailer in the past, but it overloads the server if you're not careful and it costs $59, so I just want to shop around a little first...
