KingSumo vs Strutta

KingSumo is a web and extension-based giveaway service for growing an email list through giveaways and sweepstakes. Entrants provide an email address and can earn bonus entries through Facebook activity, social-account follows, link clicks, or friend referrals. Giveaways can be shared or embedded on a website, with multiple prizes and winners supported. KingSumo sends entry confirmations and reminder emails, while the organizer selects winners and must contact them separately. Invisible reCAPTCHA checks entries in the background on every plan. The free plan costs nothing and includes unlimited giveaways, bonus entries, GDPR compliance, embedding, reminders, multiple prizes and winners, and basic integrations. The Lifetime Plan costs $49 as a one-time purchase, billed as a single payment, and adds custom branding, Meta Pixel and conversion tracking, custom rules and terms, additional entry fields, and sponsored-entry removal. SendFox works on every plan; Mailchimp, ConvertKit, Klaviyo, and Zapier require the Lifetime Plan.

Strutta is a social promotions platform for building and managing contests, sweepstakes and other campaigns that aim to generate leads and engagement. Campaign formats include photo, video, audio and text contests, quizzes, polls, coupons, landing pages and signup forms. They can run on the web, Instagram, Facebook or in an iFrame. Contest tools include moderation, judging interfaces, voter-data export and support for multiple media types; sweepstakes can use random draws, instant wins, code validation or refer-a-friend incentives. Teams can customize promotions with CSS or drag-and-drop tools, then use social sharing, promotion tracking and Google Analytics. A documented developer API uses JSON or XML for experiences such as contests, UGC galleries and voting. Standard costs $240 a month billed annually, and Pro costs $400 a month billed annually. A 7-day trial is available, but there is no free plan. Enterprise pricing is by quote and requires a setup fee and 12-month commitment.
