Jumplead has a range of merge tags available for including in the body and the subject line of your emails. When working within the Jumplead email builder these are available from a dropdown menu, but they can also be added manually to subject lines or the source code of an email you are coding by hand.
Some merge tags will produce a URL. You’ll need to add the link yourself.
Sometimes you might want to display a merge tag and alternatively fall back to a standard piece of text if the information in any particular contact record isn’t available.
