Welcome to Stamped 🥳!
By the end of this guide, you will have reviews up and running on your Shopify store. Follow the steps in order: the early steps are prerequisites for the later ones, and skipping the script step is the single most common reason widgets do not appear.

1. Sign up for Stamped
If you haven't signed up for Stamped yet, you can do so here.
2. Install Stamped app
- Head to the Stamped app listing page on Shopify
- Click Add App and follow the instructions
Navigate to the full Stamped platform by clicking the Open Stamped App button in your Shopify dashboard.
3. Add the Stamped script to your theme
Please do not skip this step. The Stamped script is not automatically added to your theme. You must install it manually on both Online Store 2.0 and Vintage themes. The script is responsible for rendering every Stamped widget. Until it is installed, nothing will appear on your storefront regardless of other settings.
Follow the instructions in our installation guide to add the Stamped script to theme.liquid. Then, return to this page.
Two things to keep in mind:
- The script must appear exactly once. Two copies cause widgets to load intermittently or hang on a spinner.
- Theme code does not carry between themes. If you later publish a new theme, the script must be added to it as well.
4. Add your review widgets
With the script in place, determine where reviews appear. Two placements are most desired on product pages:
- Main Widget - the full reviews section, including the write-a-review option
- Star Rating Badge - the stars and review count, usually under the product title
On an Online Store 2.0 theme, both can be added in the theme editor without using code: go to Online Store > Themes > Customize, open your Product template, then use Add section for the Stamped Main Widget and Add block for the Stamped Star Rating, position them where you want and click Save.
On a Vintage theme, or if you want the badge somewhere the theme editor cannot reach, such as collection pages, paste the widget code into your theme files instead.
Full instructions for both, including collection page badges, are in Installing the app, main widget and script.
You can customize how each widget looks in your dashboard under Settings > Widgets > Main Widget, and browse other layouts under Display Widgets. See the Display Widgets showcase for examples.
5. Verify your widgets are live
Open a product page on your live storefront and check all three:
- The star rating badge appears under the product title
- The main widget appears further down the page
- In the page source,
widget.min.jsappears exactly once
Test a product that already has at least one review. A product with no reviews displays an empty widget, which looks like a failed installation but isn't. If nothing renders at all, the script from step 3 is almost always the missing component.
6. Store information and email deliverability
In your dashboard, go to Settings and set:
- Store name
- Store email
- From email (the address your review requests are sent from)
- Logo
- Social: connect your accounts
- Deliverability: add the SPF and DKIM records for your sending domain
Why the From Email and deliverability settings matter: review requests sent from a domain that has not been verified can be filtered to spam or rejected outright by the recipient's mail provider. Stamped will show the emails as sent, but customers never see them, which is one of the most common causes of "review requests aren't sending" reports. Completing the deliverability step now avoids that.
7. Set up and enable your review requests
Next, set up your review request content and sequence. These are delivered to your customers according to the Intervals you set. Use the layout dropdown to try different designs, and send yourself a test.

Once you're happy, switch them on: click the Enable Review Requests toggle and Save.
If you also use Stamped Loyalty
Loyalty has its own on-theme requirement. On an Online Store 2.0 theme, the loyalty launcher is delivered as an app embed and will not appear on your storefront until you enable it.
- In your Shopify admin, go to Online Store > Themes
- Click Customize on your active theme
- In the theme editor sidebar, open the App embeds panel
- Find Stamped Loyalty in the list and toggle it on
- Click Save
If your loyalty program is configured in the dashboard but no information appears on your site, this toggle is the most common reason. As with theme code, app embeds are per theme, so re-enable it on any new theme you publish.
Optional: import your existing reviews
If you're switching to Stamped from another review platform, import your reviews with a CSV.
- Export your reviews from your other platform as a CSV file
- Edit the file to match our required headers
- Go to Settings > Importer in your Stamped dashboard
- Upload your file and click Save
See the full import guide, or email us and we can help. If you're brand new to reviews, skip this step.
Bonus: What's next?
You're live! Here are a few things worth doing once reviews are flowing:
- Set your email branding
- Add social icons to your email footer
- Connect Klaviyo to trigger flows from review events, or to send review requests by email or SMS from Klaviyo
- Set up Google rich snippets so your star ratings can appear in search results
