Thunderbird vs IncrediMail Comments
The closest thing to Incredimail on a Mac that I know of. At least you can change the "theme" of the interface to keep the app from being boring. Good, reliable program.

- Thunderbird is Free and Open Source
- Thunderbird is Customizable and Privacy focused




























































It works and it works great.
