# Slingshot

> Slingshot is a back-in-stock app for Shopify. It collects email and phone signups when products run out, sends alerts the moment they restock, and ties every alert to the sale it earned.

## What it does

- Collects shopper signups via an embeddable on-site widget the moment a product goes out of stock
- Sends email alerts the moment the product restocks (SMS coming soon)
- Reports per-alert revenue attribution so merchants see which channel, template, and audience pay back
- Targets Shopify merchants doing 100 to 10,000 orders per month who lose revenue to stockouts

## Channels

- Email — all plans, eight built-in templates: three free (Clean, Minimal, Streetwear) plus five premium industry designs (Fashion, Beauty, Jewelry, Supplements, Home), DKIM-verified custom-from domain on Scale
- SMS — coming soon (US/CA)
- On-site widget — all plans, no-code embed that customizes to brand

## Pricing

- Free: $0/month, 50 notifications/month, email channel
- Growth: $19/month ($15/month annual), 1,000 notifications/month, email + on-site widget, email overage at $0.01 capped at $30/month
- Scale: $49/month ($39/month annual), 5,000 notifications/month, email + on-site widget, custom-from email domain (SMS coming soon)
