KingSumo Review: Free Giveaway Tool With a $49 Pro Upgrade
KingSumo runs viral email giveaways. Free tier has unlimited contests, and a one-time $49 Pro adds branding removal, tracking and Mailchimp, Kit and Klaviyo.
Five AppSumo lifetime deals that cover parts of what ZoomInfo does, from contact data to cold email and local prospecting, and who each suits.

| Tool | Suits | Price |
|---|---|---|
| LeadOcean | For data-only prospecting | $49 |
| WarmySender | For cold email in one bill | $59 |
| LeadsAgent | For local-business prospectors | $79 |
| SiteBeacon | For web and SEO freelancers | $79 |
| TexAu | For LinkedIn and Maps scraping | $69 |
If you’re pricing out ZoomInfo and wincing at a recurring bill for data you use in bursts, a one-time payment looks very appealing. The catch is that none of the five tools below does everything ZoomInfo does. Each one covers a slice, so the real decision is which slice you actually used. We haven’t tested any of these hands-on. What follows is what the AppSumo listings show, including the gaps.

LeadOcean is the closest to a straight database swap. It starts at $49 and lists 693M people, 63M companies and 366M records with email. There are no credits to buy. You get fixed allowances for life.
Those allowances are where you should look closely. Tier 1 caps CSV export at 5K rows a day and phone reveals at 100 a month. That’s fine for a solo seller, tight for anyone building big lists. It also works through Claude, ChatGPT and Cursor, plus a REST API, which is a nice touch if your workflow already lives there.
What’s missing matters more. It’s data only, so there’s no CRM, no sequencer and no email sending. The listing gives no accuracy or bounce figures, and AppSumo’s own summary mentions occasional data quality issues. I’d treat the 60-day refund window as the real test: pull a few hundred contacts you can verify and see.
WarmySender starts at $59 and bundles a sequencer, warmup, verification and a 200M-contact lead database. One bill instead of four is the pitch, and for someone sending cold email for themselves or a few clients it’s a sensible one.
The sequencing side is more detailed than you’d expect at this price. The visual builder has eight conditional branch types, and A-Z testing runs up to 26 subject lines. There’s a pre-send spam score checker, and Bounce Shield verification flags catch-all addresses.
Now the soft spots. The plan feature table in the listing is unlabeled, and some numbers look inconsistent between the six tiers, which run from $59 to $999. Monthly lead and verification caps still apply even though the deal is lifetime. The deliverability and database claims are self-reported with no method shown. Start low and check deliverability yourself.

LeadsAgent costs $49 and lets you search in plain English instead of filter menus. It flags businesses with no website, which is a ready-made opening line for a web agency. Researched leads stay saved after your monthly credits run out.
But credits and AI messages expire every month, and the email checks are domain-level only, not inbox-level. If you send at volume, that means more bounces than a verified list would give you. Site analysis and multi-city search need two codes, so the useful version is $98, not $49.
SiteBeacon takes a different angle. At $79 it scores up to 20 local businesses per search on website, reputation and Google Business Profile, then drafts outreach. Drafts and hosted scorecards cost no credits. Credits refresh monthly for life, and top-up credits never expire.
The entry tier is thin, though: 150 monthly credits, one seat and no API. White-label scorecards need the $349 tier. The listing doesn’t mention contact data, exports or CRM integrations, so you’d find the business here and the email elsewhere. The product also looks young.
TexAu is a desktop app, and that shapes everything about it. At $69 you get the full automation library, running locally so scraped data stays on your computer. You can preview data before a run and see success, failed and skipped row counts. There’s no limit on connected accounts, and proxies are supported.
The tradeoffs are blunt. There’s no public API, no cloud app, and CSV is the only way out. Tier 1 allows 50 runtime hours a month and one automation at a time. The listing also contradicts itself on details like 110+ versus 150+ automations and the CRM integrations, which makes me cautious about trusting any single number on that page. The summary we have doesn’t mention a refund window.
If you already have a sequencer, LeadOcean is the cleanest fit. If you don’t, WarmySender saves you buying one. Freelancers selling websites or SEO to nearby shops should look at LeadsAgent or SiteBeacon first. TexAu suits someone comfortable running a tool on their own machine who wants LinkedIn lists in a CSV.

Four of the five list a 60-day refund. Use it. Pick the lowest tier, run a real campaign’s worth of prospects through it, and check the bounce rate before the window closes. Nothing in these listings can tell you that, and it’s the number that decides whether a lifetime deal was cheap or just inexpensive.
Not as a like-for-like swap. Each tool here covers one slice, such as contact data, cold email sending or local-business scoring. The listings give no sign of the CRM-grade enrichment a large ZoomInfo contract usually implies, so match the tool to the part you actually used.
LeadOcean lists 693M people, 63M companies and 366M records with email. WarmySender claims 200M contacts. Both figures are self-reported, and neither listing gives accuracy or bounce rates.
LeadOcean, WarmySender, SiteBeacon and LeadsAgent each list a 60-day refund window. The TexAu summary we have doesn't state one, so check the AppSumo page before you buy.
