GiveLab vs KingSumo

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.
