If you run a Facebook page for your company you should give visitors the option to register for your newsletter.
Our partner atipso has created an application for this purpose, which allows you to easily add a CleverReach form to your Facebook page.
After installing the application you will see a new tab on your Facebook page. As admin of the Facebook page you will be able to access the configuration at the top. Here you need to enter the API key of your CleverReach account and can then select a recipient group and a corresponding registration form.
The form is now active and your Facebook users can register for your newsletter.
