I would never put those two in the same pot.
I think your exchanges and wallets should have their own email. They are part of your financial information and almost as important as your banking, credit card and other financial accounts. I say almost as important because I also think that crypto and non-crypto related financial information shouldn't be
together.  

Social media on the other side has ads, promotions, remainders and other stuff that you could click on but you shouldn't mix them together with your crypto exchanges or wallets.
