SPAMASSASSIN - FILTER YOUR EMAIL MESSAGE CONTENTS
The SpamAssassin feature provided by MailMule allows you to validate the contents of your email and a few other aspects of your email itself. This can drastically reduce the number of emails that go into spam and result in a higher quality of inbox delivery.
Naturally the onus is on you to ensure that your email is something of high quality that the recipient actually wishes to recieve and enjoy; however assuming you have this in place we can certainly help you in keeping your email out of the junk folder and in some cases direct it into the inbox!
