To do this, open the Contact Form 7 form in the editor then click on the “Noptin” tab to reveal newsletter options.
Next, map the fields on your form to Noptin fields.
You can map any field on your form to any of your Noptin custom fields.
If you do not map the “Subscriber Email” field, Noptin will not add new submissions to your newsletter. All the other fields are optional.
Finally, click on the “Save” button to save your changes.
