This is by no means an exhaustive list, but hopefully it can help.

1. Add the following to your email signature

   
   

   I will never ask you to wire transfer money without talking to you on the phone first. If you receive a request to send money, please call me first to confirm.

   
   

2. When you are making a booking and need payment details, call your client, and have a conversation.  Remind them of the following

   1. "Never provide any payment details to anyone else regarding your travels – I will always be the one talking to you about this"

   2. "Don’t email any payment details to me – it is not secure and not how we request payment details"

   3. "Always call me if anything seems even a bit suspicious."

   4. Explain that Bad Actors have endless tricks to gain your trust and get your payment details or get you to wire money – and once it is gone...it is gone.
