The upgrade

Stop babysitting Facebook comment threads.

Here’s what running a 20-spot drop looks like before and after installing signup.sale.

Before

  • ×Paste a Facebook post, track 200+ comments by hand
  • ×Copy emails into a Google Sheet, dedupe manually
  • ×Pick winners. Screenshot random.org to prove fairness
  • ×DM 20 winners individually with Shopify links
  • ×Chase non-claimers for 24 hours
  • ×Pick replacements. DM again. Wait. Repeat.

After

  • Paste one link in your Facebook post
  • Entries dedupe automatically (email + phone)
  • One-click fair draw, commit-reveal proof public
  • Winners get emailed a time-boxed claim link
  • Unclaimed spots auto-expire and reroll to waitlist
  • Orders appear in Shopify like any other purchase
Why it works

Built for the way maker communities actually sell.

Fair by default

Commit-reveal random draws. We publish a hash before the draw and reveal the seed after, so anyone can verify the ranking wasn’t cooked. Arguments with cryptography, not with you.

Automatic reroll

Spots unclaimed within the claim window silently expire and pass to the next person on the waitlist. No more DMs, no more revenue sitting in a box because you forgot to chase.

Shopify-native checkout

Claim links open a Shopify checkout with your negotiated rates, your shipping rules, your accounting integrations. signup.sale never touches the money.

Dedupe & blocklist

Normalized email, phone, and optional hCaptcha keep casual duplicates out. Per-shop blocklist for the bad actors you already know by name.

Scheduled windows

Set the open and close times when you create the drop. The signup page auto-opens, auto-closes, and auto-draws — even if you’re asleep.

Discord & Zapier

Fire outgoing webhooks on every drop event. Pipe drop activity into Discord, Slack, Klaviyo, or Zapier without leaving the dashboard.

Public signup page

A hosted page you can paste anywhere.

Every drop gets a clean public URL like signup.sale/your-shop/summer-ti. Drop it in your Facebook group, Instagram bio, or newsletter. Buyers enter with just an email — no account required.
