Field Descriptions

Email Details (Required)



Click View Simon Templates in Content to open the Content Editor in a new tab for the template you've selected. If you haven't selected anything, the template list opens for you to view and open an existing template.

Optionally, use Jinja in your Subject Line

Contact Addresses

The template you chose populates these fields, or you can edit them directly in the channel action:

  • From Email: The email you want to appear in the from field in the delivered email (not necessarily the email you want replies delivered to.
  • From Name (Optional): Sometimes called a friendly from name.
  • Reply-To Email (Optional): Address you want replies routed to should a contact reply to your message. If left blank, Simon Mail defaults routing replies to the From Address.

UTM Parameters (Optional)


UTM Parameters automatically append these Google Analytics key/value pairs to the query string of all the hyperlinks in the selected template so that you do not have to hard code those parameters into your hyperlink code one by one yourself.

Disable Default UTM Parameters or Customize Defaults

We include UTM parameters by default, but you can choose to disable this feature either by flow, or globally.

  • To disable the UTM parameters for the current flow only, add the SparkPost action then toggle the Add UTM parameters to links option to off:
