SES slow to send received emails to S3

Question

I have a verified domain set up in SES that saves received emails to S3 and I do some processing on it from there. This has been working completely as expected for a few weeks (at very low volume) but as of this afternoon it has taken up to 50 minutes for an email to arrive in S3. I have been testing at a slightly higher frequency but not more than once per 10 minutes.

Is there anything that could cause this or is SES just slow today?

Thanks in advance

Hello AWS-User-9039557
     
There are many factors that can influence the speed of SES:

* You could have a bottleneck; test this by sending multiple test emails as quickly as possible.
    * Using only a single thread or using only a single process.
    * Having your application far away from the SES API endpoint.
    * Using only a single machine
    * And more
     
You can also test SES by using a different email domain, sending email from the SES console, and sending email from Gmail, and comparing the results to see if you have a domain issue.
