Netflix is probably using emails from 500px's data breach for email marketing
I've been using username+secondarykeyword@gmail.com trick for quite some time.
Earlier this year, I started getting weird emails from Netflix. They're weird because I'm already an active Netflix subscriber, but the emails are for inviting me to join Netflix.
When I took a closer look, I noticed that the email was for username+500px@gmail.com

I only ever use that email for registering with 500px. I'm also aware that 500px experienced a data breach on 2018.
So I'm highly suspicious that Netflix is using emails info from other websites' data breach for marketing purposes (knowingly or not).
This is very worrying, IMO. How do you know the email really comes from Netflix and isn’t just a phishing attempt?
