Katalyst:  Email notifications not sent to submitter when new experiments are created

Description

• When specifically set up, creating a new experiment in Katalyst should automatically send an email to:
  • The experiment submitter, and
  • A configured distribution group or email address.
• Users report that no email is being received, even though the Katalyst UI operation (experiment creation) succeeds.
• The environment is a server‑side installation where email settings are handled via configuration files and/or MongoDB configuration records.

Solution

• Verify that the email configuration is correctly set up in the Katalyst environment:
  • SMTP server hostname, port, and security settings.
  • Sender address and any required authentication.
  • Recipient addresses or distribution groups configured for experiment‑creation events.
• Check the Katalyst server logs for any email‑related error messages following experiment creation (e.g., SMTP connection failures, authentication issues, invalid recipients).
• Confirm that the configuration in the application’s data store (such as MongoDB) matches the intended email workflow:
  • Notification types are enabled for experiment creation.
  • Templates point to valid recipient lists.
• Once corrected, create a test experiment with a user who has a valid email address and confirm:
  • The submitter receives the email.
  • The configured group or shared mailbox receives the notification.
• If the environment uses external security or mail gateways, involve infrastructure teams to trace whether messages are being blocked or quarantined.
