Getting started
Do I need to edit my theme code?
No. Turn on the Preorder app embed from Home → Enable on theme, then save in the theme editor. That one embed powers every storefront feature.
Can I run preorder and back in stock on the same product?
Yes. On the Back in Stock Products tab, choose Show Notify me and preorder buttons together, Show only preorder or Show only Notify me.
Can I have several campaigns?
Yes. You can create as many Preorder and Back in Stock campaigns as you need, each with its own products, design and schedule. Use the Active/Inactive switch to turn each one on or off.
Where can I get help?
Use Chat with us on Home for live chat, open the Document page in the app, or email [email protected].

What is "Continue selling when out of stock" and why does it matter?
It is a Shopify setting that lets customers buy at 0 inventory, and preorders need it. With Automatic mode the app manages it for you. With Manual mode you manage it, and banners point out products that don't match.
How do I limit the number of preorders?
Tick Limit inventory for all products on the Preorder products tab and enter a quantity. When it's reached, "Continue selling" is turned off. In All products or Specific collections mode, you can set per-variant limits with Add variant override.
How do partial payments work?
Customers pay a deposit (1–99%) at checkout and Shopify charges the balance a set number of days later. This needs selling plans and Shopify Payments.
Why did the selling plan sync banner appear after saving?
The app attaches your campaign's variants to the selling plan in the background, so saving is instant. Large catalogs can take a few minutes, and new products are picked up by an hourly re-sync.
Can customers see an expected ship date?
Yes. Choose Scheduled fulfillment with days after checkout or a fixed date. The date is used in customer emails, and a fixed date also tags orders preorder-ship:YYYY-MM-DD.
Which emails do preorder customers receive?
Confirmation, Reminder before ship, Shipped and Cancelled. You can turn each on or off, edit and translate it, and test it from the Customer emails tab.
Can I translate the preorder button and emails?
Yes. Use Add translations on the Content tab and Add / edit translations on each customer email. Languages come from your store's published languages.

When are restock emails sent?
Automatically, when a variant's inventory reaches the Once inventory is above or equal to value. You can also use Notify now… on the Subscribers page.
What happens if a product sells out again?
Customers who were already notified are re-subscribed automatically once the Re-subscribe cooldown (days) (default 30) has passed. Set it to 0 to turn this off.
Can I require customers to confirm their email?
Yes. Turn on the GDPR Compliance option on the Email tab. Customers are then subscribed only after they click the confirmation link.
Does the email sequence keep sending after a customer buys?
No. The sequence stops for a subscriber as soon as they purchase the product.
Can I export my subscribers?
Yes. On the Subscribers page, use Export → Full data (CSV) or Marketing list (CSV), which leaves out unsubscribed customers.

The badge or card button does not show on my theme. What can I do?
Make sure Show on product cards is on in the Design tab. If your theme uses custom markup, add selectors under Settings → Theme compatibility (advanced), or contact support and we'll help.
What does Mixed Cart do?
It controls carts with both in-stock and preorder items. You can allow it with a banner, allow it and ship separately, or block it with a modal. It also adds In stock or Preorder badges to cart lines.
Can prices show the currency code?
Yes. Turn on Show currency codes in Settings to show prices such as 45.00 USD.
Pricing & email limits
How much does the app cost?
The app is completely free, with every feature included.
Is there an email limit?
The built-in sender includes 100 emails per shop per month. When you reach it, a warning appears in Settings, but sending is not blocked. If you connect your own provider (SendGrid, Mailgun, Brevo, EmailOctopus or SMTP), the app sets no limit.
Why are emails still sent from the default address after I set up my provider?
Your sender email must be verified first. Click Send verification email in Settings and open the link. Until then, the built-in sender is used.
