i'm quite new in Hubspot and just created an E-Mail template with HTML + HubL.
My question is, can I integrate a sending adress in the code? So when i open the template for sending an E-Mail the sending adress is already set by the HTML+HubL?
Just to clarify, are you looking to auto-populate the sending addresses using HTML + HubL here:
If so, this is currently not supported. However, if there's a list of contacts that you'd like populate as recipients, you can do so creating a list and include the list as the recipients.
