Deactivate this e-mail so that customers do not receive it.

Hello, can we at least deactivate this e-mail so that customers do not receive it?

Unfortunately, it is currently not possible to prevent the signer from receiving the email confirmation for successfully signed documents.

I've gone ahead and escalated your request to our Developer Team. When or if it's developed depends on their workload, how viable it is, and how many other users request it. If there are any updates, we’ll circle back to this thread and let you know. 

Do get back to us if you have any other questions.

Thank you!
