Ask boss to check client mail

Here's an example email or message you could send to your boss:

"Hi [Boss's Name],

I was wondering if you could check the client mail for me. I need to review some important messages from our clients and I'm not sure where to start. Could you please take a look and let me know if there's anything urgent that I need to attend to?

Thanks in advance for your help!

Best, [Your Name]"

Alternatively, you could also ask your boss in person or over the phone:

"Hey [Boss's Name], can you take a look at the client mail for me? I need to review some messages from our clients and I'm not sure where to start. Is there anything urgent that I need to attend to?"

Remember to be polite and respectful when asking your boss for help, and try to be specific about what you need them to do.
