I'm building a healthcare-related web service where users contact professionals via a form on profile pages. Privacy is really important, so I need an email service that doesn't store sent emails and removes them from the server once delivered.

I've been looking at services like Postmark and Resend, but they all store emails for a set period. Some (like Postmark) offer zero-retention, but require 6+ months of use and 10,000+ lifetime emails sent.

I'm just launching this as a personal project to help a few people, with no certainty of growth, and can't meet the requirements or additional costs.

Questions: Are there any zero-retention services for new, low-volume senders?

Has anyone dealt with a similar use case in healthcare? How did you resolve it?

Advice appreciated!

I'm located in Europe.
