Description

Briefly describe the changes and why they are needed.

Changes Made

• Backend changes
• Frontend changes
• Database schema changes
• Configuration updates
• Other

Testing & Verification

• Unit tests pass
• Manual testing completed
• No breaking changes

Verification Steps:

• Ran through each of the acceptance criteria, manually tested that an email was sent
• Tested mass emails by sending to me personal email and a 10 minute mail account, only tested a few at a time to avoid throttling/excess costs

Screenshots (if relevant)

Donor message test

Mass email test

Lapsed Donor test - lapsed donor = last donation > 6 months ago

Future Improvements/Notes

• refinement for templates, email currently goes straight to spam and the image doesn't load
• unit tests?
• I commented out auth for testing, auth needs to be enabled before shipping

Great job!! everything works as expected. i verified the ses flow with my own keys, confirmed the automated dono response fires and sends me an email, i also checked that bulk sending works.

i'm requesting some changes mainly for security (authguard commented out), but while u are at it, there is just a couple more things and this feature will be solidified!

• Re-enable the AuthGuard: we cant leave endpoints for bulk sending and template management public, or anyone could send spam or overwrite our settings.
• as a standard, we need to have plain-text alternatives and a proper unsubscribe link in the footer.
• make sure images are hosted on a cdn/s3 instead of being referenced locally. I will be doing that when i build the email signature.
• add some basic logs for bulk failures and wrap the variable replacements in try/catch.

Additional notes:

• i just built the save/load logic on the frontend so changes don't disappear on refresh.
