Add Dynamic Content To The Subject Line Of Plain Text Email

About this task

Although you can't directly add dynamic content to the subject line of a plain text email message, there is a workaround you can use to sync the dynamic content from the subject line of an HTML email message, over to the subject line of the plain text version of an email message.

Tip: You can directly add dynamic code to the subject line of a plain text email message. For more information on dynamic code, see Dynamic Code.

To sync dynamic content to the subject line of a plain text email message:


  1. Choose to create a new or edit an existing HTML email message.
    This will take you to the Edit Message page.
  2. Click Make Subject Dynamic.
  3. Choose the conditional.
    By default, for the first block, you can only choose if.
  4. Choose the operator. The available operators are:
    • In List
    • In Segment
    • On SMS Keyword
    • Field Is Blank
    • Field Is Equal To
    • Field Is Not Equal To
    • Field Is Greater Than
    • Field Is Less Than
    • Field Is Checked
    • Field Is Not Checked
    Note: The Field Is Checked and Field Is Not Checked operators can only be used with fields created with a type of checkbox.
  5. Choose a value.
    The values that you can choose from depend on the operator you choose in the previous step.
    Note: The value you enter when using one of the field operators is case sensitive.
    1. Click OR to add an additional value.
  6. Add the content that will be displayed if the dynamic content conditions are met.
  7. Optional: You can use the Insert Field Tags and Insert Special Tags pull-down menus to add Field Tags and Special Tags to the content area.

    Tip: For more information on adding nested conditionals and additional dynamic content blocks, see Add Nested Conditionals and Edit Dynamic Content Blocks Using The Dynamic Content Editor.
  9. Click Insert Dynamic Subject.
  10. Make sure the Sync HTML and Text Subjects box is checked.
  11. Click the Text Version tab.
  12. Click Re-generate from HTML version.
    You will see the dynamic code that represents the Dynamic Content you added in the subject line of the HTML version of your message now displayed in the subject line of the plain text version of the email message.
