Hello all,
this is my first post in the forum

I wonder if you can help. I need a sentence to explain a client that I am unable to accept the contact s/he has sent back to me as his/her signature is not what we consider an electronical signature (in this case the client "signs" the contract by filling in the blanks by typing...)
My atempt is:
"Thank you for your email. Unfortunately, while we do accept electronically signed contracts sent by email, we are unable to consider/accept this contract as signed. In fact, we require a digital picture of your signature at the bottom of the contract. We would be very grateful, if you could fulfil our requirements."
How does it sound to you? Do you reckon this is an enough polite request?
Many thanks in advance for your help.
