My CC'd recipient doesn't get the PandaDoc email
CC'd recipients should get the document along with everyone else when it is sent. There might be a possibility, you have Signing order enabled for the document. In this case, make sure your CC'd recipients are put before the Signers. Just click Manage > drag the CC'd recipients above the others by their number( if your document was already sent, you would need to "Edit" the document first.)
Warning:
If you edit a sent document, all signature and initials fields filled out by recipients will be erased to protect the signer from having signed an altered document.

Once done, send out the document and your CC'd Recipients will get the document along with the 1st Signer.
