Looker - Schedule delivery email footer

Is there a way to remove the footer in the email indicating the specific user that created the schedule?

The only way I am aware of to do this is to use the “Custom message” option in the scheduler modal to change the text that appears there.

The custom message does not remove the footer:
This email was scheduled by xxxx. Click here to unsubscribe xxxx@xxx.com.

I was inquiring about a way to remove the footer that is added by default.

You are quite right. Unfortunately, I’m not aware of a way to suppress that message if you are scheduling to email using Looker’s default SMTP.
