EarlyParrot allows you to stack up rewards encouraging your referrers to get more referrals to qualify for more expensive, limited and desired rewards. Setting up rewards is very easy and is covered in this article
Keep adding rewards for the same stage (Lead Stage or Customer Stage), increasing the number of referrals required to qualify for the reward.
For instance:
Rewards #1: Free Stickers – 2 Referrals
Rewards #2: Free T-Shirt – 5 Referrals
Rewards #3: Free 1-year membership – 10 Referrals
EarlyParrot will monitor all your referrers and referrals. Once a referrer reaches a milestone, they will be automatically sent out the associated reward.
