Cartlet – Share, Save & Track Carts for WooCommerce

See what works

• Shares, opens, saves and restores for the last 7, 30 or 90 days, with a daily chart.
• Every saved, shared and merchant cart is listed in Cartlet → Carts: search, filter, view, expire or delete.
• A REST API and WP-CLI commands ( wp cartlet list , stats , purge and more).

Fits your store

• Buttons below the cart, in the mini-cart, on the checkout and on product pages – classic templates and blocks (Cart, Checkout and Mini-Cart blocks) alike.
• Blocks: Cart button (Share or Save), Saved carts, Cart link preview. Shortcodes: [cartlet_share] , [cartlet_save] .
• Button styles that follow your theme, or solid, outline, soft and text-link presets, with icon-only mode.
• Every template can be overridden from your theme ( yourtheme/cartlet/… ); emails are edited like any WooCommerce email.
• A clean admin with light and dark modes and a 60-second setup wizard.

Lean and private by design

• About 4 KB of JavaScript and 4 KB of CSS (gzipped) on pages with buttons – nothing on other pages. No jQuery on the storefront.
• Modules you switch off load no code at all.
• No calls to outside services. Opens are counted with a fingerprint that changes daily and cannot be turned back into an IP address.
• Data is exportable and erasable through WordPress’s privacy tools, and removed on uninstall if you choose.
• Works with HPOS, page caches (links and private pages are never cached; buttons refresh their security token when a cached page is old) and right-to-left languages.

Cartlet Pro

Cartlet Pro is a separate add-on that turns shared carts into a sales channel you can measure:

• Revenue for every link, channel, campaign and sharer , conversion funnels and top products.
• Google Analytics 4 and Meta Pixel events, and CSV export of carts, links and reports.
• Cart links that close deals: price lock for quotes, customer pre-fill, source and UTM tags, opens limits and checkout landing.
• Rich link previews with a picture of the products when a link is pasted into WhatsApp, Facebook or Slack.
• Private share links with passwords, expiry and opens limits chosen by the shopper.
• Emails that bring shoppers back: saved-cart reminders, price-drop and back-in-stock news, and follow-ups for sharers.
• Smart substitutes under unavailable items, folders and tags for saved carts, and full design control .
• B2B: purchase approvals, branded PDF quotes, role and product rules, and webhooks for your CRM or Zapier.

Cartlet works fully on its own; Cartlet Pro only adds features.

External services

Cartlet makes no requests to outside services by default.

Cloudflare Turnstile (optional). If you enter Turnstile keys in Cartlet → Settings → Advanced, the “Send by email” and guest “Save cart” forms show a Cloudflare Turnstile check, to keep bots out. The Turnstile script is then loaded from challenges.cloudflare.com when a shopper opens one of those forms, and when the form is sent, Cartlet sends the Turnstile token and the visitor’s IP address to Cloudflare to verify it. Nothing is sent while the keys are empty. Cloudflare’s terms and privacy policy apply.

Share buttons. The WhatsApp, Messenger, Telegram, X, Facebook, Pinterest, LinkedIn, SMS and email buttons are plain links. Nothing is sent to those services unless a shopper clicks one, which opens that service with the cart link to share.

Cartlet Pro features. Google Analytics 4, Meta Pixel and webhooks are features of the separate Cartlet Pro add-on, not of this plugin; this plugin never contacts those services. The “Get Pro” links in the admin open getcartlet.com in your browser only when you click them.
