Change default email alert template of Grafana

Is there a way to change the email alert template of grafana? I would like to create my own template like putting my logo of the email? Is it possible?

This is the defaul template, but I would like to custom it.
Hope you can help me.

I need too! Someone can help?

I never got lucky doing it.
I did my own customized program to do it.

I already know it.
The email alert template is under the folder “email” in grafana. It is an html file that you can easily edited.
