Just curious on what to use to create web based emails for my customers advertising needs. I run a golf site with opt-in subscribers which provides a solid email listing for all the golf run business in the area. I need to create professional looking emails (not just text based) to be sent out. I have no real idea how to do this but I assume there are companies out there that provide (for $) software that helps you create these. Any help would be greatly appreciated.
P.S I'm interested in keeping the email database on my end as I would like to keep it secure and private if possible. I don't want another company to have access to my email listings. Not sure if this is even an issue or not.
