I believe I got blocked for sending too many emails to one address by gmail. I have an application I made and I had email notifications on. It was sending a lot of notifications recently. I have since altered it so I don't send so many, however it seems I was too late. I got blocked for sending too many emails from my site to my gmail account.

Is there a way to appeal this at all?

The reason for being blocked is due to sending too many emails.


At Gmail Support area there's the reference to the daily sending limit, which is 500 messages per day or a huge number of undeliverable messages.

In an effort to fight spam and prevent abuse, Google will temporarily disable your account if you send messages to more than 500 recipients or if you send a large number of undeliverable messages. If you use a POP or IMAP client (for example: Microsoft Outlook or Apple Mail), you may only send a message to 100 people at a time. Your account should be re-enabled within 24 hours.

As stated, your account should be back within 24 hours. If you want to keep using Gmail, you can use Google Apps, as the limits are higher (2000).

My recommendation is that you use a professional Email Sending service like Amazon SES.

  • I was not sending email via Gmail I was sending email TO a Gmail address. – ComputerLocus Nov 30 '14 at 16:35
  • The principle should be the same, and the restriction will be removed within a few hours.

  • I am still being blocked despite it being the next day. – ComputerLocus Nov 30 '14 at 21:50
  • And these emails are simply being sent to my own address, I don't care to use a professional service for this. – ComputerLocus Nov 30 '14 at 21:51
  • Have you solved your problem? – nunorbatista Dec 5 '14 at 18:58

You can increase your ranking by adding a Sender Policy Framework to your domain. See:- http://www.openspf.org/SPF_Record_Syntax
