Referral programs priced by participant
GrowSurf runs a refer-a-friend program for a product rather than a one-off giveaway: every participant gets a link, the rewards fire automatically, and the tax paperwork on the payouts is handled. It bills on how many people are in the program rather than on how many you refer, which is unusual and worth understanding before you launch.
Our note
The pricing model is the thing to think hardest about: paying per participant is generous if your referrals convert and punishing if they do not. Run the trial with real traffic before committing to a year.

Giveaways with a lifetime price tag
KingSumo runs the bonus-entry giveaway that grew half the email lists of the last decade, and it sells a lifetime licence rather than a subscription. The free tier covers unlimited giveaways with bonus entries and reminder emails. Branding controls, tracking and integrations are all on the paid side, and the sponsored entry stays on your giveaway until you pay.
