We are running Sitefinity 6.1
We have a Contact Us form that gets submitted by anonymous users.
The form has the fields: First Name, Last Name, Email, Phone, and Address.
We were wondering if we could add a checkbox that says "Please subscribe me for the newsletter" and whenever the form is submitted and that checkbox is true to add them into the subscriber list and into the corresponding mailing list.
Please let me know what would be the best way to achieve this.
