Klaviyo: Connect every profile, list, and audience signal to your full stack
Klaviyo manages profiles, lists, templates, and subscriber data. Tray connects Klaviyo so audience and subscription activity triggers workflows across your stack, and agents can query or act on the same profile and list data.

Use cases
Klaviyo + Tray
Klaviyo is where email and SMS audience data lives: profiles, lists, segments, flows, campaigns, and templates. On its own, Klaviyo doesn't sync subscriber data to your CRM, route list membership changes to your data warehouse, or enroll profiles based on events in connected systems.
Tray bridges the gap, turning profile and list activity into multi-step workflows that call Klaviyo's API, apply logic, and write to every system that needs to act.

Automations
Automations with Klaviyo and Tray
Tray workflows can run on a schedule to pull Klaviyo list and profile data, reconcile it against connected systems, and act on changes: subscribing, updating, or removing profiles as audience records shift across your stack. For more responsive patterns, external systems can call Tray to push data into Klaviyo in near real-time as events occur in your CRM, ecommerce platform, or product analytics tool.
Once triggered, workflows can branch on list membership, profile properties, or subscription status, route results to connected systems, write back to Klaviyo (subscribing profiles, updating properties), and push data downstream. They can also be exposed as agent tools.
Integrations
Integrations with Klaviyo and Tray
Klaviyo holds your email and SMS audience, but the signals that should drive enrollment, suppression, and profile updates live in your CRM, ecommerce platform, product analytics tool, and data warehouse.
Tray connects Klaviyo to those systems so profile subscriptions, list membership, and audience data flow in both directions. The Tray Klaviyo connector handles API authentication and provides named operations for the most common profile and list workflows.
For capabilities beyond those such as campaigns, flows, segments, events, and metrics, the raw HTTP request operation provides authenticated access to Klaviyo's full REST API without managing tokens in each step.
Klaviyo integration capabilities
Integrate Klaviyo with 700+ applications plus any system with an API using our HTTP connector. These domains mirror Klaviyo’s API and how teams actually work in Klaviyo.
Read and update Klaviyo profiles to keep audience data accurate across your stack
- Profile retrieval: Get individual profiles by ID to surface contact data in downstream workflows or sync records to connected systems
- Profile updates: Update profile properties including custom attributes, consent status, and contact details to keep Klaviyo in step with your CRM or CDP
- Profile subscription: Subscribe profiles to lists to enroll contacts in Klaviyo audiences based on events in connected systems
Agents
Build agents with Klaviyo and Tray
Tray agents turn Klaviyo audience and profile data into action. They ground on approved profile, list, and template context, then call governed tools to update records, manage list membership, and answer marketing questions. Every outcome writes back to Klaviyo and connected systems, so teams can ask, act, and audit in one continuous flow.
Ground agents with the audience context they need to act accurately
- Object scope: Access profiles, lists, and templates via named operations; access campaigns, flows, segments, events, and metrics via authenticated API calls
- Freshness: Query live Klaviyo data on demand or run scheduled checks using list and profile retrieval operations
- Scoped access: Limit agents to the Klaviyo objects and operations relevant to their role
Frequently Asked Questions
Find answers to common questions about our products and services.
What named operations does the Tray Klaviyo connector support directly?
The connector's named operations cover profiles, lists, and templates, specifically getting and updating profiles, subscribing profiles to lists, and listing templates. Anything beyond these requires the raw HTTP request operation.
Can Tray access Klaviyo campaigns, flows, and segments?
Yes, via the raw HTTP request operation, which provides authenticated access to Klaviyo's full REST API. This covers campaigns, flows, segments, events, and metrics without requiring you to manage API tokens manually in each step.
Does Tray support event-driven Klaviyo workflows?
The Klaviyo connector does not have a dedicated trigger. Tray workflows can run on a schedule to poll for list or profile changes. For near real-time patterns, external systems can call Tray workflows to push data into Klaviyo as events occur.
Can Tray subscribe profiles to Klaviyo lists in bulk?
Yes. The Subscribe profiles operation accepts multiple profiles in a single call, making it suitable for batch enrollment workflows triggered from external systems.
How does authentication with Klaviyo work?
The Klaviyo connector authenticates using a private API key. Create a private API key in your Klaviyo account under Account > API keys, select the required scopes, and paste the key into Tray's authentication setup.
What's the best way to start with Klaviyo + Tray?
A workflow that subscribes profiles to a Klaviyo list when contacts meet defined criteria in your CRM is a practical first automation, and a good foundation for more complex audience sync workflows.
FAQs
