Now that you get this email like this, what do you expect the community to do? Should we help you export the wallet and send the BTC to you, or what? As far as I know, there is a very high possibility that this might not be a real wallet or that this might be a multiple-signatory wallet where you need more than just those key phrases to get whatever is inside the wallet out. 
 
And beside what they shared with you without a wallet address, which can be publicly accessed to confirm if it's real or not, you can investigate further. If I must advise you, unless you were expecting such an email from someone you know, I will advise you to stay very careful with what kind of information the sender might ask from you.
