How to I check my mail?

Hello! I logged on today and saw that I had mail! Though I forgot the command to read it…I tried “/mailbox” but it didn’t work…
Can someone comment below the command I use??

To check mail you right click on a owl! You can access a owl by clicking your pet leash and taking it out of you have one, or you can floo to “great hall” and walk out the door to find one, or do /spawn and walk to the entrance of Diagon Alley where you will once again find another owl.

Ah, thank you so much!
