If they don't protect it with such as Docusign or other secure e-mail or method, then yes, it is out on the open internet. It's a long shor, but people -- very techy ones -- can intercept that.
I had done it via Dcusign and other secure method. But then I realized those are simply VPN-style security, and now I figure I can get as much out of using my own desktop Docusign at the same time as having the VPN turned on, I figure that would be double security.
But for incoming, that's another matter, yes. But, does the bank send it via their VPN, and if so, then it still is secure -- to the level that VPN offers. At one bank, they told me all their e-mail is sent through secure channels automatically. I don't know how true that is.

I was on a 30 day Federal Grand Jury and heard numerous cases. A few were bank tellers who stole from customers.
