ReferralHero vs SparkLoop (2026): which should you pick?

Pick ReferralHero if

• Fits if you run a waitlist or launch campaign and want it built from templates
• Works for a local service business that wants a hosted referral program

Look elsewhere if

• Pricey if you are small: Basic is $249 a month for 1,000 subscribers and one campaign
• Tight if you want free: there is no free plan and the trial lasts 7 days
• Watch out: emails past 25,000 a month are $1.50 per 1,000, and reward payouts carry fees from 2.5% + $0.50
• Not for you if you need the API or unlimited campaigns without paying $399 a month
• Watch out: mobile SDK access and mobile attribution need an annual plan

Pick SparkLoop if

• Fits if you already send a newsletter and want more subscribers
• Works for publishers happy to run on an existing platform like beehiiv or Kit

Look elsewhere if

• Not for you if you need a tool to send email, as it doesn't
• Pricey if your list is small, since referral programs are a $2,000-a-year add-on
• Watch out: the price of subscribers bought through partner programs isn't on the pricing page

ReferralHero

• Subscriber count is capped at 1,000 on Basic, which also allows only one self-serve campaign.
• Emails over 25,000 a month cost $1.50 per 1,000; SMS is pay-as-you-go by country.
• Reward payouts carry processing fees from 2.5% + $0.50 per payout.
• Mobile SDK access and 10,000 mobile attribution subscribers require an annual plan.

SparkLoop

• It does not send email; you need an existing email platform to send your newsletter.
• The referral program is a $2,000 a year add-on, so it is a sizable cost for small lists.
• The price of subscribers bought through partner programs is not shown on the pricing page.
