In Gmail Is There a Way to Have Outgoing Emails Automatically Bcc'd to Me?

Currently the answer is that there's not a direct way to automatically bcc yourself in Gmail. But, every outgoing email is copied into your Sent Mail folder for future reference.

 

You can also create filters in Gmail as outlined here: https://support.google.com/mail/answer/6579?hl=en 

 

With that information, each of your office staff can create a filter based on their email address that basically says "search All Mail for messages from: self@maidpro.com and then forward it to self@maidpro.com" or something similar. 

Either of these above options are effective alternatives to the automatic bcc.
