Fix Unwanted Random Email Intrusions

My inbox has been flooded by emails from random strangers ever since I signed up for a website that, unfortunately, currently eludes my memory. This situation leads me to believe my email information was leaked or shared. Despite my efforts to address the issue by checking my email's spam folder and trying to unsubscribe from these mailings, I have had no success.

What I mainly want is to get my information removed from whatever website I signed up to, so that no one can email me

I am seeking a tech-savvy freelancer with experience in:

- Cybersecurity
- Email client operations
- Investigative ability to trace back spam sources

The job entails:

- Identifying the root cause of the problem
- Teaching me how to block unwanted emails from different senders
- Offering reliable methods to protect my email and personal information from future breaches
- If possible, identifying the website I originally signed up where the problem could have started.

As this situation implicates my privacy and peace of mind, dedication, promptness, and a thorough understanding of the issue are paramount qualities I look for in my freelancer.
