I get asked a lot about the different rules at each ISP, and how to find more information on these policies. Here is a short list of the most common domains I get asked about;
- AOL – http://postmaster.info.aol.com/
- Gmail – http://www.google.com/mail/help/bulk_mail.html
- Hotmail/MSN – http://postmaster.msn.com/
- OutBlaze – http://spamblock.outblaze.com/
- Yahoo – http://help.yahoo.com/l/us/yahoo/mail/postmaster/
These pages contain many helpful resources that will help you understand the policies, practices, common questions and tools available from each ISP.
Have others to list, or need to know about a specific ISP – let us know or leave a comment.
