The application lets you create email lists of any size and send as many emails as you want. In these emails there obviously won't be any banners or announcements that you don't want to be there.
One of the application's features includes the ability to link directly to a registration form on a website. That way, the mailing list can grow itself without your having to do hardly anything (though this is available in the business version only).
FollowUpExpert is quite a comprehensive tool for sending automated emails. It's not only easy to use, but also offers certain advantages for the recipients of the emails, too.
The trial version doesn't let you send more than 500 messages.
