How do i send a copy of my passport?

I recently signed up for payoneer, i got an email saying "unfortunately we were unable to process your application, please provide the following...
1. A copy of your government-issued ID (passport, national ID etc,)
2. A prove that your living out side of your country...
I replied to that email sending my passport scan and a picture of my apartment contract, because i moved to a different country...
My question is...
Did i send my stuff to the right email or do i have to send it to a different email?
Its been 2 days with no reply.
