The Pre-Header is a small phrase that usually appears on your incoming email list, right next to the subject (e.g.: Gmail, Hotmail, Yahoo). When not defined, the Pre-Header assumes the first words contained in the email message.
With this feature, you will be able to use the pre-header as a strategic complement to help boosting your campaigns’ openings.
Ideally, this text should be a striking phrase, something to induce the subscriber to open the message!
