Bloom Shopify App Logo Bloom Shopify App Logo Bloom is a Shopify app with three tools that turn an out-of-stock variant into captured revenue instead of a lost sale. All work at the variant level and integrate with Add to cart, cart and checkout.

What Bloom does

  • Pre-order Sell stock before it arrives. When a variant runs out, Add to cart flips to Pre-order with a ship-date message. Oversell limits cap how far inventory goes negative, so you stay in control.
  • Notify Me Capture demand on sold-out variants. Sign-ups flow to Klaviyo, and shoppers come back by email or SMS the moment stock returns. Campaigns add custom questions to the sign-up form.
  • Recommendations Send shoppers on a sold-out variant to something they can buy now. See Recommendations.
Each feature has its own section in the Bloom sidebar - Pre-order, Notify me and Recommendations - with Overview, Activity, Configure products, Design, Content and Settings tabs. You control visuals, messaging and behaviour per product, template, market or locale.

​
How it works

​
Notify Me

Customers sign up to a sold-out variant. Stock returns, the form switches off, and Klaviyo emails the customers.

​
Pre-order

Enable pre-order and set the maximum you can pre-sell. When the variant is out of stock, customers buy on pre-order until it hits your maximum. When stock goes above zero, pre-order switches off.

Quick start guide

The Quick start guide walks you through setup in under 10 minutes.
  1. Enable Bloom in your theme - one theme embed, no file edits

  5. Curate Recommendations - optional, off on the Hibernate plan

​
Why merchants use it

  • Capture revenue you’d otherwise turn away. Pre-orders sell through a stock gap; Notify Me recovers shoppers who’d leave a sold-out page.
  • Set expectations clearly. Ship-date messaging on the product page, cart, checkout and order status page means fewer “where’s my order?” tickets.
  • Stay in control of oversell. Per-variant limits stop pre-orders running past what you can fulfil.
  • No developer needed. One theme embed turns it on; everything else is configured inside Bloom.
  • Works with your stack. Sign-ups sync to Klaviyo flows; pre-order and Notify Me events fire to your analytics platforms.

Update Shopify’s order confirmation for full clarity and enable customers to cancel and see changes to estimated shipping timing. Every order is tagged Pre-order for easy filtering and reporting.

Notify Me
