Sending paused, no emails received...

If you open the AWS Support Center, you should see an open support case that is a copy of the email you should have received from Amazon SES.

The Amazon SES console also contains a reputation metrics page that will tell you the reason that your account was paused.

I recommend setting up CloudWatch alarms. When you set these up, you'll receive notifications when your reputation metrics reach whatever thresholds you define.

As an additional step, you can set up automatic pausing for your account. When you set up this feature, you can automatically stop your account from sending additional emails when your bounce or complaint rates reach certain levels. Then, you can address the issue that was causing the high bounce or complaint rate, and resume sending when you're ready. This way, you don't have to go through AWS Support in order to have your sending un-paused.
