For a more convenient collection of signatures on time there is reminders feature in Dokobit portal. Even if you use deadlines, the reminders allow you to make sure everyone signs on time by giving you an additional option to manually prompt other parties about their pending signatures.
Sending a reminder to signer
1. If there is a pending signature, click on a “Send a reminder” button to remind the signee you’re waiting for their signature.
2. You can also add a personal message if needed. After inserting the custom message click "Send" button.
Note: If you haven't prohibited signing after deadline you can send reminders whenever, no matter whether the set deadline has already passed or not. You won't be able to send reminder if you checked the box "Do not allow signing after deadline" - then the "Send the reminder" button is not visible after the deadline has passed.
