A few months ago, I got in touch with a recruiter that was offering job positions for an industry I'm interested in. I sent my CV to her, she requested some changes to it, then more changes.
In the end, I only ever got asked to change stuff on the CV and that my salary requirements were too high etc. but never got any job offer.
In the meantime however, I was able to get offers myself relatively easily, with the same CV and same salary. So I let her (politely) know that I'd be already in touch with a company and thanked her for the effort that she already put in.
I didn't receive any reply to this until a few weeks later - she asked me in an email if there are any updates to my job search. I was quite surprised by that, because how my job search is going is private matters and I didn't reply (that might have been rude.)
Since then, I got three more emails with the same content from that person. My question is:
How to make it clear that I don't want to be in touch anymore without starting an argument via email?
