I want to find Alex Y. Arnold’s email address since he has often tweeted he wants diverse and #ownvoices books.

he’s Editor at Katherine Tegen Books at HarperCollins Publishers. But though I find his blog, twitter, etc I cant find his email to query him. If anyone can find it, can you please post it so I can query him? Thanks!

Btw does anyone know if he’s a man or woman? Alex could be a woman’s name and I don't want to get it wrong when I address him.
