I believe there are tools like saymine.com which help you send an email to the company, citing all the laws that obligate them to delete all your data. Source: about 1 year ago

I used a website that automatically sent emails to any company, that had my email address on their contact list, and it sent them a notice to delete any data they had on me (under GDPR), since then I haven't had spam calls. The site I used was called saymine.com, there's others like that but this one was trustworthy. Source: over 1 year ago

Use saymine.com. This service scans your email address to see which services have your data so you can verify you have everything deleted. Apart from this, keep it around for a while to make sure you get everything. Source: over 1 year ago

Your best bet would prob be something like saymine.com, it works by searching your inbox for account creation emails so might not get everything but is a good start. Source: over 1 year ago
