When the driver completes a stop, your customer can receive an email with the proof of delivery attached: the photos and signature the driver captured.
Before you start
Your stops must have the customer's email.
Drivers must capture proof of delivery in the app (photos and/or signature). You choose what they capture in Project settings → Driver app → Stop data.
How to turn it on
Go to Project settings → Communication → Automated messages.
If you already have an email with the Delivery completed event, open it with ⋯ → Edit. If not, click New message, choose Delivery completed and Email, and click Create.
In the left panel, under Attach proof of delivery, turn on Images, Signature or both.
Check the email text and send yourself a test with ⋯ → Send test.
From then on, every customer with an email receives the delivery completed notice with their proof attached.
