Please alert (someone) of (a problem)
If you want people to tell you about something, you can use this expression in formal English:
Please alert Management of any issues with the equipment.
"Please alert (someone)" means "Please tell (someone)." You "alert" people like:
- the police
- tech support staff
- building owners
of things like:
- suspicious activity in your neighborhood
- problems with machines
"Alert" is more formal than "tell" and it sounds more serious and urgent.
