I've been looking all over the internet, and testing various email programs to find a Mac-based email app that lets me do all the standard email functions while managing contacts & groups internally. My purpose is to manage incoming/outgoing emails, plus contact info and groups for a non-profit group I started. I just want all the info self-contained in the app so that it doesn't merge with, or infringe upon my Mac OS's default Mail and Address Book application data. I've tried Sparrow Lite, Mailings, DirectMail and LogicalMail, but all of these programs either don't offer an incoming mail option, or an address book function. Is it impossible to find something that combines both functions? The icing on the cake would be if I could find something that allowed me to set throttle parameters for doing semi-bulk mailing instead of just putting everyone's email address in the CC field.
