The best way to ensure your mail is delivered to Gmail users is to comply with our Bulk Email Senders Guidelines. An example of a guideline is that a user must be able to unsubscribe from your mailing list with a prominent link or replying to your message with the word 'unsubscribe.' If you are sending mail in accordance with our guidelines and Gmail continues to mark your messages as spam, you can contact the Gmail Team by filling out this form.
Please provide the full headers for specific examples of bulk messages you sent that you believe Gmail incorrectly marked as spam. We'll use the information you provide to investigate, and improve our spam and abuse detection systems. We're sorry, but we aren't able to provide reports about our findings once we've investigated. Thanks for taking the time to send us the requested information -- if we need more details, we'll contact you.
