About
SparkLoop is a London-based newsletter growth company that provides referral marketing and cross-promotion tools specifically designed for email newsletters. Newsletter creators use SparkLoop to set up subscriber referral programs — rewarding existing subscribers with merchandise, digital products, or other incentives when they refer new subscribers — and to participate in cross-promotion partnerships with other newsletters that have complementary audiences. SparkLoop's partner network connects thousands of newsletters for mutual audience growth, with creators earning paid newsletter subscriptions from partners' audiences and growing their own subscriber lists through the network. The platform integrates with major email service providers including Mailchimp, ConvertKit, Beehiiv, and Ghost. Founded in 2020, SparkLoop has grown rapidly as the newsletter creator economy has expanded and creators have sought cost-effective subscriber acquisition beyond paid social advertising. The company raised funding and has facilitated millions of newsletter referrals. It competes with ReferralHero and newsletter partnership tools built into ESPs in the newsletter growth market.
