True. I try to keep my work mail away as much as possible from any website if it can be avoided. When I use a third-party app that I would do in my web dev job, I usually try to use a dummy account and would use random characters for the name since Gmail really requires them anyway. Kinda makes it hard though when you are required to connect your work email, lol.
I lost track of all my emails that I used back in 2015, but good thing it never involved any of my personal information.
We've all done it. I imagine most of us have multiple emails that have been lost with time. The good news is from a marketing stand point, most data that's a couple of months old isn't very useful for advertisers so they won't link you up that way. If your emails do have your personal information you've just got to hope that your password was unique, and wasn't used anywhere else. Since, even if you have the strongest password in the world in terms of it being random, if you use it multiple places, and one of those places gets compromised. You could potentially be compromised since that opens up a window of possibilities in terms of attack surface.
Although, you'd be surprised how many websites actually store your personal information, and credentials in plain text.
