We Contact You will tell you that our site unintentionally revealed your email address due to a technical error . The problem is solved. This is not a result of everything you have done, and it is not necessary for you to change your password or take other actions.
The advice "do nothing" misses the point: "revealed" means a lot of spam in my mailbox. Amazon should, as goodwill, enter a credit on my account or someone for goodwill given this unacceptable incompetence. It's now either set up with spam or eliminate an email I've used heavily for 20 years (literally).
It's a good practice to use temporary email addresses for many websites so that if your email address is retrieved by spammers, your email address can be changed.
