We too are experiencing this same issue with our Azure hosted instance which is using AWS SES for mail.

2023-04-14T17:18:56.908014860Z: [INFO] - failed to send email with template signup_email (app/services/email/awsses/awsses.go:122)

This issue is confirmed by us as well. Preventing us from using the service as people cant sign up

I tried to set this up in Heroku using either SMTP or Mailgun. Using current version as well as stable.
Emails are indeed not being sent, product is unusable.

Has anyone been able to fix this issue in a fork?
