As you are assuming your are in the largest category in googles categories the “normal” category. If this is true and I bet it is not your going to be targeted as you are.
The way I see it. The only way to not loose is to not play the game.
You mentioned professional use of google. I can understand looking for a job, feeling overwhelmed but who you use for email will probably not make a difference.
I imagine most jobs which require a professional email will supply you with one. I am lucky that mine is nickname.last_name@mycompany.com I only use it for company related emails in fact I am changing the email for 401k and health insurance. Too much cross contamination.
Sorry this off topic.
