@Marvin Is there an alternative to using username/password authenticate, e.g. SMTP relay, to send email using the prefect-email package?

It appears that your concern is quite unique, or my search parameters were not quite up to scratch; there are no existing GitHub issues specifically about using SMTP relay authentication with the prefect-email package. If the usual username/password authentication does not suit your taste due to its mundane nature, perhaps you might consider investigating other means of sending emails in Prefect that leverage the use of Prefect Blocks for secrets management or integrating with email services that support API-based sending. The Prefect documentation or further searching might yield alternative solutions. If you wish for me to continue the search or provide more detailed assistance, please let me know.
