My name is ALWAYS mistaken for a man’s name so I frequently get addressed as “Mr.” It’s frustrating so I added “Ms. A— Mimes” to my signature line in my email. It’s politely professional and maybe a tad passive-aggressive.
I thought about doing that in my signature with Mr. Executive too but it sounded too weird in German. And we have a corporate design for our email signature so I can’t add it there.
I also don’t think “Ms. A- Mimes” is passive aggressive in the least. It’s how they handle it in the UN, too.
