How to send a nice message by asking the boss for salary?

Use polite address and clearly indicate your intention.

1. Use polite address: you can address the boss as Mr. or Ms., or you can use the boss's name directly, which is polite and respectful.

2. state your intention clearly: state your intention clearly at the beginning of the message, for example, excuse me, I'm XXX, and I want to discuss the salary problem.
