E-Mail Notifications with Frigate Detections

TL;DR: How do I get attached inline email notifications with Frigate images?

I am currently running Blue Iris with Deepstack on an NVIDIA Tesla P4. it works, but its not very reliable, and it uses a lot of power for what it does.

I’ve setup Frigate on a Beelink N100 box, with an M.2 TPU, and I have the alerts tuned to perfection.

I have push notifications setup which work perfectly, but we like getting emails as well.

I can only figure out how to get HA to send an email with a linked image, meaning the server has to be accessible from where the email is viewed. I would like the image to be attached, and inline in the email. Has anyone figured this out? Here is an example from Blue Iris

That image is in the email, so it doesn’t need to talk back to my home network at all. How do I get HA to do this? I have SMTP setup and working, I just don’t know how to get the image to actually attach and show up like this
