How can recipients get access to a contract sent to them for signatures?

If you are one of the Signees of a contract you have received for signature, you will be able to access the contract from the signing link in your email which requests your signature, while the contract is Pending.

Once the contract has been signed by all Signees (fully signed) you will be able to access it from your Contractbook account, directly from the Signed Tab of your Documents overview or from the email notifying you it was fully signed. 

Can any recipient get a PDF version of a contract they signed?

Once a contract is fully signed, all Signees, disregarding their type of Contractbook plan, will receive an email notification. They can download the contract as a .pdf directly from the email by clicking on the button Download the contract.
