The 42U Jetpack Booster adds redirect tags and HTML email templates to Jetpack Contact Forms.
To add a redirect to your Jetpack Contact Form, just add a text field named “redirect” to your form. It will be hidden on display.
From the HTML view, set the default value to the location where you would like the form to redirect after submission.
[contact-field label=”redirect” type=”text” default=”/thanks/” /]
Note: you must replace the default each time after editing the form with the Jetpack WYSIWYG editor. The value is not saved by Jetpack.
