What are velocity controls?
Velocity controls prevent too many vouchers from being issued to or by a single customer. They're useful to avoid situations like the 'Stephen Fry effect', where a well-known person shares a referral link and their followers claim all available rewards quickly.
Using velocity controls sets a limit above which rewards won't be automatically issued. Instead, they need manual review and approval before being given out.
These controls track rewards given by referrers to referees across different offers and periods. You can set limits per day, month, or year.
You can apply velocity controls separately on the referrer and referee sides. If set on the referrer side, it limits rewards given to a referrer. If set on the referee side, it limits how many referees can claim an introductory offer from a single referrer.
To set velocity controls, go to Campaigns, click on the experiment, and edit details. Standard controls include:
- Maximum 5 rewards for a referrer in 24 hours.
- Maximum 25 rewards for a referrer in a year.
- Maximum 10 new customers introduced by a referrer in 24 hours.
Note: "Introduced" means customers started the referral process by entering their email, not necessarily making purchases.
