Hello Blake,
Thanks for reaching out.
I bought a ESP Company that was doing email marketing using Interspire for about 6 years. Most of their clients were using it to send bulk spam emails, and that’s why it has about 80 million blacklisted emails.
It seems like a pretty good list, as I was complained by Spamcop, which resulted to shutting down my Mailwizz server including webpage.
That’s why I quickly decided to spend Usd 5,000 to buy that experienced ESP Company to avoid future shut downs.
After importing this blacklist into Mailwizz, I found the complainer that complained to Spamcop. Also found the email address of my IT person, and he confirmed he was a frequent complainer. Also imported a small list in MailChimp, and they would not allow me to use this list. So three confirmations I received confirming this list is quite valuable to have and that I made the right decision.
Please PM me, and let me know what amount you have in mind.
Thanks,
