You can make money from any legit email list. You just need to change the approach.
So, you have the domainers list, as most people here said, don't spam them with "Buy my domain" emails.
I really won't recommend you to do it this way.
If I had these emails, I would have used them in the way of "what domainers are actually looking for?"
They find the so-called "Premium domains" themselves easily using tools expireddomains.net and other auctions, also they do keep on searching on the various aftermarket.
So, I would have used this list for a newsletter, or stories behind domains, domain offers from different registrars, like how domainsmoke did it. Read tweets from searchcloud, dotweekly, waren, you have a lot of content around the domain industry. Just make it interesting for the domainers, research, and find something new. Then comes the earning part. Be affiliate with different registrars and put them in the newsletter relevantly. Keep your domains for sale at the bottom of the email. If this gets appreciation, you can have sponsored domain listings from fellow domainers. Don't spam but feed what people looking for.
