What KingSumo is
KingSumo is a giveaway and sweepstakes tool for growing an email list. Entrants register with an email address and can earn extra entries through Facebook activity, social-account follows, link clicks, and friend referrals. Organizers can share campaigns or embed them on a website, offer multiple prizes and winners, and view analytics and reporting. KingSumo sends entry confirmations and reminder emails, while organizers select winners themselves; the service does not automatically choose or email winners. Invisible reCAPTCHA checks entries on every plan. The free plan supports unlimited giveaways, bonus entries, GDPR compliance, embedding, reminders, multiple prizes and winners, and basic integrations. The Lifetime Plan costs $49, paid once as a single payment and adds custom branding, tracking, custom rules, extra fields, and sponsored-entry removal. KingSumo is available as a web service and extension.
