Pricing Plans: Back in Stock Notification Limits and what happens when you Reach Them (Essential Preorder app)
This article explains how the monthly Back in Stock notification limit works on each Essential Preorder plan, what the app does as you approach it, and what happens when you reach it. It is for shop owners who run Back in Stock campaigns and want to know what a plan covers.
Registrations versus notifications
- Registration: a customer signs up to be notified. Registrations are unlimited on every plan.
- Notification: the email the app sends when the item is back in stock. Only notifications sent by Essential count against your limit.
Notifications sent through Omnisend or Shopify Flow are not sent by the app, so they do not count.
Notifications are counted per calendar month (UTC). The count starts again on the 1st of each month, not on your Shopify billing date.
Where to see your usage
- Home shows a usage bar with notifications sent this month against your plan limit.
- Pricing plans shows your current plan, its limit and the rate above the limit.
Limits and rates per plan
| Plan | Notifications included per month | Above the limit |
|---|---|---|
| Free | 300 | No overage. Sending pauses at the cap |
| Lite ($4.95/month) | 1,000 | $0.01 per notification ($1.00 per 100) |
| Starter ($8.95/month) | 2,500 | $0.01 per notification ($1.00 per 100) |
| Essentials ($24.95/month) | 10,000 | $0.01 per notification ($1.00 per 100) |
| Professional ($59/month) | Unlimited | No cap, no overage |
Example: Lite includes 1,000 notifications. Send 1,250 and the 250 extra cost 250 × $0.01 = $2.50. Overage is charged per notification, not rounded up to blocks of 100. It is billed through Shopify as app usage charges and appears on your Shopify bill.
Warnings on the Free plan
You get an email at 50% and again at 80% of your monthly allowance (150 and 240 notifications). At 80% a banner also appears on Home: sending will stop at the cap. At 100% you get a final email and the banner changes. Preorder limits warn differently, at 20%, 50% and 70%. See Preorder limits.
What happens at the Free plan cap
- The app keeps collecting new registrations.
- The app stops sending notifications until the count resets on the 1st of next month.
- Nothing is lost. Registrations that were due to be notified wait.
- Upgrade and the app sends the notifications that were due, then carries on with new ones.
What happens on a paid plan
Paid plans never pause sending. Past your included notifications, the app keeps sending and you are charged $0.01 per extra notification. You get one email when you pass your included amount.
Common questions
Does a customer signing up count?
No. Only the alert email the app sends counts.
Do limits reset monthly?
Yes, on the 1st of each month at 00:01 UTC.
I use Omnisend or Shopify Flow to send the alert. Does that count?
No. The app records the signup and your other tool sends the email.
Where do I upgrade?
Pricing plans in the app. See Plans and billing.
Still stuck?
Contact support from the app with your store name. We can see how many notifications were sent and when.
