When reaching out via email, please use encryption. Either S/MIME or PGP.

Please note that you should not trust the keys just because they come from here. If you assume that someone can read the traffic between you and me, then you have to assume that this person can change the data and give you a false key. Trust in the key can only be built by going to keysigning parties and then collecting evidence of validity via the Web of Trust through intermediaries.
