Does anyone specify their pronouns in email?

Just had an email from a person with first name Alison. Underneath it said pronouns she/her. No shit - you're a woman. I deduced that from your first name but I don't actually care what gender or whatever you claim to be we're just doing business. Don't know whether the pronoun bit is the organisation policy or something she chooses to add.

Had to answer professionally but was so tempted to say if you want to bring pronouns in to the equation wouldn't it be way cooler to be them/they
