Run subscription emails from Klaviyo, next to the rest of your marketing

Overview

Curobi's Klaviyo integration sends nine subscription events to a merchant's own Klaviyo account as metrics to build flows on, keeps four subscription fields current on each customer profile for segments, and can hand Curobi's own customer emails to a Klaviyo flow — on every Curobi plan, including Free.

Curobi sends nine metrics, each named with a Curobi prefix so they never mix with another app's: Subscription Started, Subscription Renewed, Upcoming Charge, Payment Failed, Payment Recovered, Subscription Paused, Subscription Cancelled, Subscription Reactivated and Payment Method Updated. Every event carries the products, the amount per charge, the frequency, the next charge date and a link for the customer to manage the subscription, and a cancellation carries the reason the customer gave. The products, amount and date also arrive ready to print, so an email reads right without any filters. The metric names never change, so a flow you build today keeps working.

Four profile fields stay current on each customer for segments: Curobi Active Subscriber, Curobi Active Subscriptions, Curobi Subscription Status and Curobi Next Charge Date. They describe the customer rather than a single subscription, so someone who cancels one of two subscriptions is still an active subscriber and doesn't fall into a lapsed segment by mistake. When you connect, Curobi sends one sample event per metric to a placeholder profile with no email address, so all nine metrics are listed in Klaviyo and ready to pick as flow triggers before any customer does anything.

Curobi already sends its own subscription emails. If a Klaviyo flow sends the same message, you can hand that email to Klaviyo — any of eight, from the confirmation and charge receipt to the pause and cancellation notices — and Curobi stops sending its copy. If Klaviyo is ever disconnected, Curobi goes back to sending those emails itself, so customers are never left with none. The failed-payment email always sends, because it is Shopify's secure card-update email and carries the only link that lets a customer fix their card.

Curobi sends Klaviyo the customer's email address, so each event lands on the profile Klaviyo's own Shopify integration already created, and the subscription details above. It never sends phone numbers, addresses or payment details, never adds anyone to a list or changes their consent, and doesn't keep the email address. It also honours the message types a customer turned off in their email preferences, apart from essential billing events. Klaviyo is on every plan, including Free, and it works on development stores, so an agency can build the flows before a store launches.

How to connect Klaviyo to Curobi

1. Create a private API key in Klaviyo

   In Klaviyo, open Settings, then API keys, and create a private key named CUROBI with Accounts set to Read Access and Events set to Full Access. Copy it now: Klaviyo shows it only once.

2. Connect it in Curobi

   Click Integrations in Curobi's top navigation, choose Set up on the Klaviyo card, paste the key and click Connect. Curobi checks the key, stores it encrypted and adds all nine metrics to Klaviyo.

3. Build a flow on a Curobi metric

   In Klaviyo, create a flow with a metric trigger such as Curobi Subscription Cancelled, write the email, and set both the email and the flow to Live.

4. Test it, then hand the email over

   Send a test event from Curobi's Klaviyo page to your own inbox. If the flow replaces one of Curobi's emails, switch that email to Klaviyo under Who emails your customers.

Questions merchants ask

Related features

• Shopify Flow

  Curobi adds seven subscription triggers to Shopify Flow, Shopify's own automation app, so a merchant can start any Flow workflow — tag a customer, alert the team, add a row to a sheet — when a subscription starts, renews, fails a payment, recovers, pauses, cancels or reactivates, on every Curobi plan, including Free.

• Cancellation Prevention

  Curobi's cancellation save flow is the sequence a subscriber sees when they try to cancel — presenting an alternative such as pausing or skipping a delivery — designed to keep customers who would otherwise leave over a fixable, temporary reason.

• Recovery

  Curobi's recovery (dunning) automatically retries a failed subscription charge on a smart schedule and sends branded recovery emails prompting the customer to update their payment method, so a recoverable card failure doesn't silently cancel the subscriber.
