Following the general bulk mail policies will help. Do the following * Clearly indicate bulk mails with list-subscription info headers * Use SPF & DKIM * Process all your bounces .. remove bouncing ids, they do maximum damage to your ip reputation. * Sign up for feedback loops wherever possible * Try getting confirmation from all the users that they want to receive the mails. There is no point sending mails to inactive accounts. Thanks Ram
