KingSumo

Open your laptop, pick a prize, and launch a contest before lunch. KingSumo gets you from idea to live page in minutes. Choose a goal—grow your list, spotlight a new product, or spark social buzz—then set the prize, dates, regional rules, and entry limits. Customize the landing page with brand colors, images, and short copy, or paste in a prewritten template. Enable quick entry via email capture and one-tap Google sign-in so people can join without friction. Hit publish to get a shareable link you can drop into an Instagram bio, an X post, Stories, or your website embed.

Drive momentum with referral rewards. Decide how many extra chances someone earns when a friend joins through their unique link, and cap it to keep things fair. Add action steps that map to business outcomes: follow or subscribe on specific channels, visit a product page, watch a demo, answer a survey, or upload a skill submission. Each completed step can grant points or bonus entries. Example workflows: a blogger runs a monthly giveaway to grow a newsletter; a DTC brand promotes a flagship item and tags entrants by interest; a SaaS team ties entries to a webinar registration; a podcaster asks listeners to vote on upcoming topics and share the link.

Manage everything from a clean dashboard. Filter entrants, add labels, merge duplicates, and export CSVs. Auto-sync new contacts to Mailchimp, ConvertKit, or your CRM with tags so sequences start instantly. Anti-cheat checks flag disposable emails, repeated IPs, suspicious velocity, and bot patterns; review alerts before confirming entries. Run paid contests with built-in payment handling. When judging skills-based challenges, keep evaluations unbiased with anonymous entries and scorecards. Prefer community input? Enable voting with throttling and anti-stuffing safeguards.

Promote smart and learn fast. Queue social posts, attach UTM parameters, and track which channels drive verified entries and referrals. Test headlines or hero images, and iterate mid-campaign. Embed the widget on landing pages and schedule reminder emails so participants come back for daily or weekly actions. When it’s time to wrap, draw winners randomly or finalize judges’ picks, generate a verifiable winner record, and announce across channels. Then convert attention into revenue: send discount codes to non-winners, invite everyone to your community, and trigger nurture flows. Start free, duplicate your best-performing template, and run your next growth sprint with less effort and more results.
