For example, for our 100k plan, your message may get sent by 1 user with ~50k followers, 3 users with ~10k each, and 20 users with ~1k each. It'll be some combination of users with followers counts totaling at least 100k.
We don't force our users to send any particular message nor do we know exactly which accounts will agree to promote your message but they are all delivered from real, active accounts which we will be able to report to you after. You do not pay by the tweet, but by the number of people your message is delivered to.
Since we're just starting this, these prices are promotional and introductory and will likely rise in the future so get it while you can!
