Amazon Hit With Major Data Breach Days Before Black Friday

3. Sounds like your email address wound up on a list that could have been seen.

Since it was not associated with the password, or credit card info, it sounds like no big deal. It terms of a "data breach" this sounds rather innocuous.

A data breach on LinkedIn exposed my password on the site and resulted in an email "from myself" to myself containing the password and a bunch of malarkey saying they had taken control of my computer, They wanted $900 deposited to a Bitcoin wallet to ensure not sending info from my system to my contacts. The password was my generic low security password, so it gains them nothing. I changed on every site that I used it.

Sounds like you don't have to do anything, other than keep an eye out for more spam and scams.
