sound Posted 6 hours ago Posted 6 hours ago (edited) Email error log when sending a bulk email fills up with errors which includes every so often the below message Amazon SES, SMTP Error Response: 421 Connection closed by server. Maximum message count per session reached investigation led to this topic here https://repost.aws/questions/QUw5qK9rBFSKqXvW5a-nAteg/amazon-ses-smtp-error-response-421-connection-closed-by-server-maximum-message-count-per-session-reached it says there may be a new limit of 350 calls from 19 Nov 2024 which fits in with the same date that they appeared in my email error log Anyone else sending over 350 emails seeing this problem?

Randy Calvert Posted 6 hours ago Posted 6 hours ago Don't use SMTP... it can slow down performance when you have very large topics as a result of notifications, and there are situations like this. There are a few third party plugins that leverages the APIs to send mail through SES using the API. For example, @Jon Erickson has one that I've personally used that is fantastic and has worked great... https://store.deschutesdesigngroup.com/buy/0182a1f0-48ea-4438-9b40-293441be9f85 @stoo2000 also has one as well. I've not personally used it, but including a link for you. https://ipb.silvesterwebdesigns.com/file/9-mail-bouncer/
