How many rewards can a referrer earn?

Single-sided and Double-sided rewards can be earned multiple times. However, this depends on the max rewards you set in the Reward editor. For example, if you select "Rewards are unlimited" in Advanced reward settings, referrers will be able to earn multiple rewards over the lifetime of your campaign.

In the case of Single-sided and Double-side rewards, the reward count will be at the top-right in the Rewards section of the GrowSurf window and the embedded rewards to represent multiple rewards earned (e.g., +3). To limit just one issuance to the referrer, set the max number of rewards to 1 in  Advanced reward settings.

For Milestone and Leaderboard rewards, this incentive can be earned one time during the campaign’s period, or the reward can be adjusted so that referrers can earn it monthly.
