Email received from Form to say "'user' via Smartsheet"

Hi all,

when a user, that a smartsheet and the respective form to be filled out were shared with, fills out the form and submits it, emails received in Outlook say:

— that would be me, but other users are the ones filling out the form and submitting it but it still shows my name (since I am the sheet owner).

For the above to happen, I configered the message and had selected "Send from triggering user". I was under the impression, that the "triggering user" was the person filling out the form. In the form that person also is required to select their email address in a drop down.

I already configured the subject line in the automation to say: {{Request Type}} submitted by {{SNet Rep}} and that DOES work and arrive correct, and as expected, in Outlook.

The only thing that doesn't work is, that the "header" of the email says - no matter who fills out the form - "Martin Maschke via Smartsheet".

What would I need to do, to have my name changed the person's name, that actually fills out the form and submits it?

THANK YOU ALL in advance!

Martin
