You can configure HTML Forms to redirect to a certain page on your website after each successful form submission.
An example use case would be to send visitors to a “Thank you” page after they submit your form.
To set this up, open up your form, navigate to the “Settings” tab and locate the setting shown below.
Make sure to use complete (absolute) URL’s and to redirect to a page that describes that the form was processed with success. You don’t want to confuse your visitors with a random redirect. 🙂
