Use this guide if you want shoppers with a Shop account to sign up for back in stock alerts without typing their email. By the end, the "Notify me" popup will show a **Continue with Shop** button under your signup button. Shoppers tap it, confirm in Shop, and STOQ signs them up with their verified email address. ## Before you begin | You'll need | Why | |---|---| | **Email alerts** turned on | Shop only shares the shopper's email, so the toggle is disabled until email alerts are on. See [Turn on email and SMS channels](https://help.stoqapp.com/back-in-stock/back-in-stock-channels/). | | The **Button + Popup** form layout | The button shows in the signup popup only. It doesn't show when the form is set to **On page**. | ## What customers will see - In the "Notify me" popup, under your signup button, an "or" divider and a **Continue with Shop** button. Shop shows both in the shopper's language. - A shopper with a Shop account taps the button and confirms in Shop. STOQ gets their verified email and submits the signup, so there's no email to type and no typos. - A shopper without a Shop account can create one in the same step, or type their email into the form as usual. - If you show the email/SMS channel selector, the button shows only while the shopper has email selected. - If **Customer name** is mandatory, the shopper still has to enter their name before tapping the button. Shop doesn't share the name. - If **Double opt-in** is on, the shopper still gets the confirmation email and must confirm it, the same as any other email signup. - STOQ sends the back in stock alert, the same way as for any other signup. Shop doesn't send anything. ## Set it up On a phone, this menu is collapsed. In the **Shopify mobile app**, tap the **STOQ** logo at the top of the screen to open it, then choose the section named below. There is no hamburger icon. See [Finding the STOQ menu](https://help.stoqapp.com/general/getting-started-with-stoq/#finding-the-stoq-menu). 1. **Open the Sign in with Shop controls** 1. In the left menu bar of the STOQ app, click **Back in stock alerts**. 2. Click the **Settings** tab. 3. Open the **Signup widget** sub-tab. 4. Click **Customize widget**. 5. Open the **Signup form** tab, then click **Sign in with Shop** in the sidebar. 2. **Turn on the Continue with Shop button** Next to **Show a Continue with Shop button**, click **Turn on**. The preview shows the "or" divider and the **Continue with Shop** button under your signup button. 3. **Save your changes** Click **Save changes**. ## Check your setup 1. Open a sold-out product on your storefront in an incognito window. 2. Click **Notify me** to open the signup popup. 3. Confirm the "or" divider and the **Continue with Shop** button show under your signup button. 4. Tap **Continue with Shop**, confirm with a Shop account, and check that you see your success message. 5. In STOQ, go to **Reports**, open the **Back in stock** tab, then the **Current waitlist** tab, and confirm the signup is there with that Shop account's email. ## Troubleshooting ### The Show a Continue with Shop button toggle is greyed out Email alerts are off. On the **Signup form** tab, click **Channels**, turn on **Email alerts**, then come back to **Sign in with Shop**. ### The button doesn't show on the storefront Check these in order: 1. You clicked **Save changes** after turning the toggle on. 2. The form is set to **Button + Popup**, not **On page**. The button only shows in the popup. 3. If the channel selector is on, the shopper has email selected. The button hides while SMS is selected. 4. Shop's button loads from Shopify. If a browser extension or a strict privacy setting blocks it, the form shows without it and shoppers can still type their email. ### Tapping Continue with Shop shows the name error **Customer name** is set as mandatory. Shop doesn't share the shopper's name, so they need to type it before tapping the button. To allow one-tap signups, open **Customer name** and uncheck **Make this field mandatory**. ### A shopper signed up with Shop but didn't get an SMS alert Shop only shares the shopper's email, not their phone number. Signups made with Shop get email alerts. ## FAQ ### Is the Continue with Shop button on by default? No. It's off until you click **Turn on** next to **Show a Continue with Shop button** and save. ### What information does Shop share with STOQ? Only the shopper's verified email address. Shop doesn't share their phone number or name. ### Who sends the back in stock alert, Shop or STOQ? STOQ. A signup made with Shop is treated like any other email signup, and the alert goes out through your normal email alert setup. ### Do Shop signups still get the double opt-in email? Yes. If **Double opt-in** is on, the shopper gets the confirmation email and must confirm it, like any other email signup. ### Does it work with the on-page signup form? No. The button shows in the "Notify me" popup only, not when the form is set to **On page**. ### Does turning it on change existing signups? No. It only adds another way to sign up. Existing signups and the regular email and phone fields stay as they are. ## Related guides - [Design the signup form](https://help.stoqapp.com/back-in-stock/design-signup-form/): Set the popup's heading, fields, button, and layout. - [Turn on email and SMS channels](https://help.stoqapp.com/back-in-stock/back-in-stock-channels/): Turn on email alerts, which this button needs. - [Collect the customer name at signup](https://help.stoqapp.com/back-in-stock/notify-me-customer-name/): Ask for a name on the signup form. - [Test your setup](https://help.stoqapp.com/back-in-stock/test-back-in-stock-alerts/): Check signups and alerts end to end.
