What does "Please update my online sheet" mean?

Hi,

I have a master Smartsheet that gets input from several "feeder" sheets.

Occasionally I get a message with a subject line that reads "Update request for XYZ Marketing Intake: Alert: ABC received - to first review team".

The body copy says "Please update my online sheet".

I have no idea where it's coming from or what it means. I've had it come from 2 different companies and when I asked one of the them, they didn't know what I was talking about.
