How can I add a default subject line and message body mailto link in the new editor?

Hi @Mettem, 

Thanks for sharing your question with us! I can definitely understand wanting to know how to do this is the new editor, happy to help! 

You can add the default  subject line and body you want to auto-populate into the link itself. The formatting of the link would be like this:

mailto:youremail@example.com?subject=Your Subject Line&body=Your Message Content

You would add the desired subject line after subject= and then add your body content after body=, replacing what is in the example. This will allow your subject line and body content to populate in the email that is opened! 

Thanks for participating in the Community!
