i need to use this html template , https://colorlib.com/etc/email-template/1/index.html  

how to add this as email https://colorlib.com/etc/email-template/1/index.html  

in Out System 

Hello Omar.

I think the easiest way to do this is by creating a traditional web app to act as a post office. I use traditional because it has the option to not escape content.

Check out this oml file. If you consume it from your application you can use the server action to send an email (assuming email is configured in service center). You can copy the html from the template you noted in your question and set that content to the "body" input parameter of the SendEmail server action when you call it.

Hopefully this helps,

Jeremy
