About Kingsumo

KingSumo is a viral giveaway and contest platform built and owned by AppSumo. It enables businesses, creators, and marketers to run unlimited giveaways that grow email lists and social audiences by rewarding participants with extra entries for sharing the contest link with friends or completing social actions (following on Instagram, watching a YouTube video, etc.). The platform is designed for simplicity: users configure a giveaway, embed it on any website via a widget, and let the viral sharing loop drive new entrants. When a participant shares the giveaway link and a friend signs up, both can receive bonus entries, creating an organic growth loop. KingSumo collects entrant names and email addresses, which can be pushed directly into connected email service providers. KingSumo integrates with MailChimp, ConvertKit, Klaviyo, SendFox, and Zapier. The paid Pro tier also unlocks custom branding (removes AppSumo branding), Meta Pixel and conversion tracking, custom form fields, 19-language translations, and advanced ESP integrations. The free tier still provides unlimited giveaways, website embedding, multiple prize support, and basic Zapier and SendFox integrations. As an AppSumo Original, KingSumo is actively maintained and available as a lifetime deal ($49 one-time for Pro) or included free with an AppSumo Plus membership ($99/year). The tool is actively listed and sold on AppSumo as of mid-2026, with no indication of shutdown or acquisition.
