Define Properties

Define Properties in Email Studio’s Send Flow allows you to preview the email you selected.

By default, the Subject and Preheader are inherited and saved from the selected email. The addition of or edits made to the subject or preheader here only applies for this send. To update what is displayed by default, edit the email. The subject and preheader can’t be edited when Approvals is enabled. To update the field, edit the actual email. The subject and preheader of shared Content Builder emails can’t be edited.

The From Options are defaulted to the Default Commercial Send Classification for the account. However, you can select from either saved verified send classifications or use account-related From and Reply names.

The maximum length of a subject line is 200 characters and is required. A Preheader isn’t required.
