Plugins for commerce shops Ounce Restock Alerts

In development Ounce Restock Alerts · for WooCommerce

Back-in-stock emails that actually send.

Brings back the shopper you lost to a sold-out page, the moment the item is back.

A back-in-stock waitlist for WooCommerce. The part everyone else gets wrong is not the form — it is whether the email leaves at all. That is the part we built the company around.

Free plugin submitted to WordPress.org — September 2026

What actually happens

Six steps, and you only do one of them.

  1. 01

    Someone wants it

    They found the product page. They were ready to pay.

  2. 02

    It says sold out

    No button. Nothing to do. They close the tab.

  3. 03

    They leave a signup

    One field on the same page: tell me when it is back.

  4. 04

    You restock

    You change the stock number in WooCommerce. That is your whole job.

  5. 05

    The email goes out

    Within a minute, to everyone waiting, in the order they asked.

  6. 06

    They come back

    Straight to the product page, with the item in stock.

Why these emails do not arrive today

Three faults, and none of them are the plugin author's fault.

The best-reviewed plugin in this category has carried the same one-star reviews for five years. Eight unrelated plugins break in exactly the same three places, because the faults are in WordPress itself.

Defect A

Page caching kills the signup form

If cache is on, it is always “Something went wrong”. I do not want to clear cache every 12 hours.

What we do: Our form carries nothing that a cache can go stale on. It works on a cached page because there is nothing to expire.

Defect B

Nothing sends until a visitor happens to arrive

When the product is restocked, an automatic in-stock mail notification is not sent. The most important feature of this website is not working.

What we do: WordPress only runs scheduled work when someone loads a page. We catch the restock the moment it happens, and we do not need your visitors to make it fire.

Defect C

Mail leaves your server and quietly dies

Constant issues... it only works right after clearing cache. I have no way to know whether anything arrived.

What we do: The free plugin sends from your site, like everyone else. The paid add-on sends from ours — with retries, bounce handling, and a log that tells you what actually arrived.

The difference in one picture

Where the email goes.

How it works elsewhere

  1. Stock goes back to “in stock”
  2. …nothing happens
  3. A visitor loads a page, some time later
  4. WP-Cron finally runs
  5. Your server tries to send
  6. Maybe delivered. No way to tell.

How it works here

  1. Stock goes back to “in stock”
  2. We catch it at that moment
  3. Free: your server sends
  4. Paid: our server sends, retries, handles bounces
  5. Delivered — and written into a log you can read
Straight answers

Questions people ask before they trust a small vendor.

Is the free plugin limited?

No. No product cap, no monthly send cap, no trial clock, no locked buttons. It sends through your own site, which is how every free plugin in this category works. If your site sends mail reliably today, the free plugin may be all you ever need.

Then what am I paying for?

Delivery, and proof of delivery. The add-on moves sending to our servers so a restock alert is not at the mercy of your host, your SMTP plugin or your traffic. You get retries, bounce handling and a log you can actually read.

What happens if I stop paying?

The free plugin carries on working exactly as before, on your own mail. Nothing you installed gets switched off. You lose our sending, not your data.

Do you keep my shoppers’ email addresses?

They live in your WooCommerce database. When the paid add-on sends, we process an address to deliver that message and for nothing else — no resale, no profiling, no use across other shops. A data processing agreement is available before you buy.

Which themes does the form work in?

Classic themes, block themes and the common page builders. The form can be placed automatically, dropped in as a block, or written as a shortcode wherever you want it.

When can I have it?

The free plugin goes to WordPress.org for review in September 2026. The paid add-on opens after it is approved. Join the list and you will hear on both days.
