Best approach for handling SMTP failures in Dynamics 365 workflows?

Hi everyone,

I’m looking for recommendations on handling SMTP/API email failures inside Dynamics 365 workflows, especially for automated notifications and customer emails.

Are most teams using built-in retry logic, external queues, or monitoring tools for failed sends? I’ve been testing a few SMTP service provider options, including DigitalAka™, to improve delivery reliability in workflow-based email automation.

Curious to know what setup has worked best for others.
