Is it possible to use merge tags in the subject of the email?

Yes, you are able to use merge tags in both the subject and pre-header fields of your emails. This is done the same way as in the body of the email.

Once you've chosen the target list for the campaign, you'll also see the custom merge tags you've created for that list. Select your merge tag from the dropdown or type it manually.
