Wait for the exact variant
A shopper waiting on Size M is not emailed when Size S restocks. Signups are stored per product and per FluentCart variation.
Available
CartCubes Waitlist for FluentCart
When a product or a specific variant sells out, shoppers leave their email and get notified when that exact item is back.
Variant-aware waitlists, automatic restock emails, and a subscriber list in the FluentCart admin.
What it does
Automatic restock emails
When FluentCart stock changes, pending waiters for that variant get a back-in-stock email. No cron job to set up.
Social proof per variant
Show how many people joined the waitlist for the selected size or color, with a counter you can rewrite.
How it works
-
1
A product or variant sells out
The form appears when that item is out of stock. On variable products it follows the selected variant, so Size M can show the form while Size S still has Add to Cart.
-
2
The shopper leaves an email
One field, email only. Guests can join by default. Logged-in customers get their account email filled in. The signup is stored against that product and that variation.
-
3
Optional double opt-in
Turn on Confirm your subscription if you want a confirm link before the email is added as pending. Leave it off and they join immediately.
-
4
You restock in FluentCart
Update stock the way you already do, including FluentCart Pro Advanced Inventory. The plugin listens for the stock-changed event.
-
5
Only that variant is emailed
The Product Back in Stock email goes to pending subscribers for the variant that came back. Restocking one size does not notify people waiting on another.
-
6
You manage the list
The Subscribers tab shows product, variation, status, and dates. Send a restock email to one person or in bulk, and use Reports to see what is most waitlisted.
Details
Waitlist settings
Turn the waitlist on, choose where the form sits, and pick which products it covers. Signups stay variant-aware no matter how you target products.
- Enable or disable the waitlist without losing subscriber data.
- Guests can join by default, or you can require a login.
- Six placements: after or before quantity, after or before price, after the product content, or shortcode only.
- Five targeting modes: all out of stock, selected categories, selected brands, specific products, or every product.
- Place the form anywhere with [cartcubes_fc_waitlist_button], including a specific variation ID.
Form
The storefront form is one email field plus a notify button. Copy, colors, the counter, and notices are all editable.
- Background, padding, and corner radius for the waitlist block.
- Rewrite the sold-out notice, email label, placeholder, and button text.
- Show how many people joined for the selected variant, with a {counter} token.
- An optional Leave waitlist button after a successful join.
- Separate success, confirmation, already-subscribed, removal, and error messages.
Emails
Five templates: subscription, admin alert, optional confirm, back in stock, and promotional. Each has a subject, heading, HTML or plain text, and merge tags.
- Subscription Email goes to the customer after they join, or after they confirm.
- User Subscribed alerts you, with its own recipient address.
- Confirm your subscription is off by default, so stores that skip double opt-in never send it.
- Product Back in Stock sends when that variant restocks, or when you send it from Subscribers.
- Tokens include {username}, {product_name}, {product_url}, {confirm_link}, and an unsubscribe link.
Subscribers and reports
See every signup with its variation, send restock emails one at a time or in bulk, and read demand from the reports dashboard. This is a notification list, not a reservation queue.
- Statuses: pending, pending confirm, notified, and cancelled.
- Filter by status, product, or email.
- Reports cover pending, awaiting confirmation, notified, cancelled, total subscribers, and products with waitlists.
- A top-ten list shows the most waitlisted products.
