Klaviyo, Gorgias and Shopify Flow, connected on every Curobi plan.

Yes, on every plan, including Free, and on development stores too. Curobi sends nine subscription events to your own Klaviyo account as metrics you can build flows on: subscription started, renewed, paused, cancelled and reactivated, upcoming charge, payment failed, payment recovered, and payment method updated. It also keeps four subscription fields current on each customer's Klaviyo profile for segments, and you can hand Curobi's own customer emails to a Klaviyo flow so customers don't get two. You connect it with a Klaviyo private API key in about five minutes. Curobi sends the customer's email address and the subscription details only — never phone numbers, addresses, or payment details — and never changes anyone's marketing consent.

Yes, on every Curobi plan, including Free, as long as your store is on a paid Shopify plan. Every Gorgias ticket shows a card with the customer's Curobi subscriptions — status, products, how often each one bills, the next charge date, and the amount — with buttons to skip the next order, pause, resume, reschedule, or cancel without leaving the ticket. You set it up with a Curobi API key and Gorgias's own HTTP integration by copying and pasting a few URLs; there is no code and nothing to install in Gorgias. Gorgias sends Curobi the ticket's email address to look the customer up, and Curobi doesn't store it.

Yes, on every plan, including Free. Curobi adds seven triggers to Shopify Flow: subscription started, renewed, payment failed, payment recovered, paused, cancelled, and reactivated. Each one passes Flow the full Shopify customer, so a workflow can check their tags or total spend, plus the product, frequency, amount, and currency, and the cancelled trigger carries the reason the customer gave. From there you can tag customers, alert your team, or run any other Flow action. There's nothing to set up in Curobi: open Flow in your Shopify admin and the triggers are there, along with four ready-made Curobi templates in Flow's template library for tagging new subscribers, tagging customers who cancel their last subscription, and flagging and clearing failed payments.

Any plan, including Free. Klaviyo, Gorgias, Shopify Flow and the developer API — API keys, subscription changes by API, bulk exports, and the Storefront and Customer APIs for headless stores — are on every Curobi plan, so none of them is a reason to upgrade and none needs the trial. Signed outbound webhooks, which push subscription events to your own ERP, 3PL or warehouse, start at Business. The API, webhooks and Gorgias need a store on a paid Shopify plan and stay off on development stores; Klaviyo and Shopify Flow work on development stores too.

Yes, but it doesn't keep them. Curobi reads a customer's email address from Shopify at the moment it sends one of its subscription emails, and, if you connect Klaviyo, to send that customer's subscription events to your own Klaviyo account so they land on the right profile. If you connect Gorgias, it works the other way round: Gorgias sends Curobi the email address on a ticket, and Curobi uses it to find that customer's subscriptions in Shopify. In each case the address isn't stored, and Curobi never sends phone numbers, postal addresses, or payment details to Klaviyo or Gorgias.

Yes. Curobi's purchase-option widget renders inside your existing Shopify theme via app blocks and app embeds — no theme swap and no separate checkout. Because subscriptions run on Shopify's native Subscription Contracts, the tools already in your stack — reviews, loyalty, email and SMS, analytics, and upsell or bundling apps — see subscription orders exactly the way they see any other Shopify order, with no proprietary billing layer to integrate around. Headless and heavily customized themes are supported through the same Shopify app-block placement. Curobi also connects directly to Klaviyo, Gorgias and Shopify Flow on every plan, including Free.
