BitBounce vs Knowies

We invented a solution to spam that charges senders of cold emails a fee for their emails to be delivered. We raised significant funds through an ICO and are now growing very quickly.

Cryptocurrency spam solution. BitBounce reduces your email spam by charging unsolicited email senders a cryptocurrency fee to send you their emails.

When senders pay your cryptocurrency fee, their emails are moved to your inbox.
