Hi there,

If you are sending a relatively large number of emails, the ideal process is to follow the Bulk Senders Guide. However, if you feel you are sending mail in accordance with Gmail guidelines and Gmail continues to mark messages as spam, please use troubleshooting links below:

1. Bulk Email Senders
2. My domain can't send to Gmail

To report a delivery problem to Google click here Report a delivery problem.

For additional information and better compliance with Google, please click on the following link Bulk senders guidelines.

Note: For regular Gmail users sending limit via POP/IMAP connection is 100 emails. Also, each sender you send to, counts as 1 email. If you send 100 emails with five people CC'd or BCC'd in each email, you'll hit your limit. Regarding the time frame; it depends on when you sent a message. If you sent 500 emails at 12pm yesterday, you won't be able to send again until  after 12pm today. If your sent messages were within this limit, but you received too many bounced messages, that also might prevent you from sending.

If you want to send bulk emails I suggest a bulk mailing service, such as Constant Contact or MailChimp.
