Real results from brands on Nonito. Yours depend on your product and pricing, so read this as a range, not a forecast. Figures in EGP.

What it is

  • A back-in-stock flow captures a phone number on a product page when the item is sold out.
  • When that exact variant is restocked, it sends an SMS to the people who asked.
  • It runs at variant level, so someone waiting for a medium hears about mediums.
  • SMS rather than WhatsApp, because the message needs to go the minute stock lands with no template approval in the way.

Who runs it

  • Brands that sell out of their best products regularly, which is most brands with a hero item.
  • One brand on Nonito runs it today, so treat the numbers here as early.
  • Anywhere variants matter: size in fashion, shade in beauty, prescription strength in optical.
  • It is worth least for brands that rarely stock out, and most for brands that always do.

How it works

  • A notify-me field appears on the page when a variant is sold out, asking only for a number.
  • The request is stored against that exact variant.
  • The flow watches inventory on the products you choose to cover.
  • When stock returns, an SMS goes to the people waiting on that variant, with a direct link.
  • A day later, anyone who has not ordered gets one low-stock reminder, and the flow ends.

Why it works

  • The demand is pre-confirmed. Nothing else in the stack has this much intent behind it.
  • The customer named the product and the variant themselves, so the message is never irrelevant.
  • A sold-out page that captures a number stops being a dead end.
  • One brand running it has seen 13% of the people it reached go on to order.

When It Is Back, They Hear About It First.

A sold-out page is a leak. Someone arrived wanting to buy, found nothing, and left with no way for you to reach them. A small notify-me field turns that dead end into a list of people who have already told you what they want and in which size.

The moment

Someone wants what you do not have

They reach the page, the size is gone, and a notify-me field asks for a number.

1 of 5

Variant level or not at all. This is the single decision that determines whether the flow delights people or annoys them.

Variant level

They asked for a medium in sand. They hear about a medium in sand. Every message is relevant.

Product level

They asked for a medium and hear that small is back. Now the alert is noise.

What Makes It Work, And What Breaks It

The difference between recovering orders and annoying people is in these details.

Do this

  • Alert on the variant, never the product

    Someone waiting for a medium does not care that small is back. This is the whole flow.

  • Send the minute it lands

    The value decays by the hour. A restock alert the next morning is competing with whatever they bought instead.

  • Set a stock floor

    Do not tell a hundred people about three units. Choose a minimum before the alert is allowed to fire.

  • Link to the variant, not the collection

    They should land on the thing they can add to a basket, already in the right size.

  • Expire old requests

    Someone who asked four months ago has bought elsewhere. Ninety days is a reasonable ceiling.

  • One reminder, then stop

    A second nudge on a low-stock item is fair. A third is a campaign they did not sign up for.

What goes wrong

  • Product-level alerts

    The fastest way to turn the highest-intent list you own into a list that ignores you.

  • Alerting on three units

    Ninety-seven people click through to a sold-out page. You have now disappointed them twice.

  • Batching the sends

    Holding alerts for a daily digest throws away the only advantage this flow has.

  • A false low-stock line

    People notice, and this flow only works because they believe you.

  • Never expiring the list

    An alert for something requested last season reads as a random advert, because that is what it is.

Questions About This Flow

Why SMS rather than WhatsApp?

It is a one-line message with a link, and it has to go the minute stock lands. SMS needs no template approval standing between the restock and the send.

What if only a few units come back?

Set a stock floor so the alert does not fire. Telling a hundred people about three units disappoints ninety-seven of them.

Does it alert on the product or the size?

The size, and the colour. Product-level alerts are the main reason this flow underperforms elsewhere.

What results should we expect?

One brand runs this today and 13% of the customers it reached went on to order. That is one account, so treat it as a signal rather than a benchmark.

How long should a request stay live?

Ninety days is a sensible ceiling. Beyond that, most people have bought elsewhere and the alert reads as a random advert.

How long does it take to go live?

Same day, once the notify-me field is on your storefront and inventory is syncing. There is no template approval to wait on.
