FAQ
Milestone Referral FAQ
How does a milestone work?
Participants invite a set number of friends to reach the first milestone and win its reward, then invite more to reach the next, up to the final reward.
What rewards work best?
Anything your audience values: a coupon at the first milestone, a T-shirt or stickers at the next, exclusive content, event tickets, or a title like official ambassador.
When does a friend count?
When they sign up, or when they convert, like a purchase or a paid plan. You choose.
How do participants know they won?
Each milestone has its own email, sent the moment it is reached. The milestone widget also shows where they are and what comes next.
Which plan includes it?
The Milestone Referral is on the Plus plan and up. Automatic rewarding is on Growing and up.
