You can track leads through email or by form submissions. There is an option in the Configuration page to track leads within our Email Templates, or you can add tracking to the links you include in the email.
For tracking leads through form submissions, ORBTR includes integrations with Gravity Forms (a premium/paid plugin) and JetPack (a free plugin). If your forms are created using JetPack, ORBTR will automatically track all submissions. If you are using Gravity Forms, the ability to activate tracking is available as an advanced form setting for all your forms.
