Hello,
I'm developing a crypto related project.
In order to launch properly, I'd like to inform people about what I'm building thanks to their emails.
Would anybody be willing to "sell" their mailing list?
Thanks
THIS IS a very bad idea to promote through email spamming. People hate this. So you had get opposite effect (negative relation) + spent money on email database.
Think about bounty campaign! if your project/idea is good people (bounty hunters) will help to promote it.
