Is there a way to customize the Adobe notification sent via email when online form is submitted ?

Hi NS6four,

Thank you for reaching out.

If you are referring to customizing the message that appears in the email on the recipient end, it can be done on the send page.

However, if you are referring to customizing the complete email, please refer to the following help document on what changes you can make: https://helpx.adobe.com/sign/using/adobesign-suppress-addresses-in-email.html. 

The information provided in the help document applies only to Acrobat Sign Enterprise and Business accounts. 

Let us know if you have any questions.

Thanks,

Meenakshi
