See, I need to hire a personal assistant to deal with email, but I'm afraid of doing the remote PA thing because I don't trust them with my email (and that's a whole other issue since that's the job I need help with) and this idea is appealing, except, as others have noted, I have no idea who this company is. What their business model is. How they make sure my personal details and payment stuff is secure. That this won't just wind up being an easy way to phish into my life.

Nope.
