Hi Ana -

For security reasons, Facebook does not allow the contact information of your followers to be included in the data you receive.

The best way for you to reach out to these contacts is through your social media engagement. For example, you can post links to your signup pages, petitions, and other action pages in your Facebook account so that your followers can provide you with their contact information.
