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 Recipients > Signing order > drag the CC'd recipients above the others.

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