Been doing this for almost 15 years. Works great. You might be surprised to see who ends up with an email address you given to a company that promises never to give it away.
I recently discovered an online vendor was hacked, possibly before they knew it themselves. I started getting banking-related phishing emails and called the company, only to be met with the telephone equivalent of deer-in-the-headlights blank stare.
Took a while to convince them HOW I knew it could NOT have been any other company on the planet letting that particular email address loose into the wild, but I think they "got it" finally.
