When Trello and Klaviyo operate independently, marketing teams often miss critical updates on project statuses. For instance, if a Trello card is moved to 'Done' but the corresponding email campaign in Klaviyo remains unaware, customers may receive outdated information about project timelines. This leads to manual data entry by the marketing team, who must constantly check Trello for updates and manually adjust Klaviyo lists, wasting valuable time that could be spent on strategy and content creation.

Top Ways to Automate Trello & Klaviyo

Automated Task Updates: Instantly sync Trello card updates with Klaviyo, ensuring your marketing team is always informed about project statuses and can tailor communications accordingly.
Triggered Email Campaigns: Automatically launch targeted email campaigns in Klaviyo based on Trello card movements, such as when a project is marked as complete or a task is overdue, enhancing customer engagement.
Centralized Reporting: Generate comprehensive reports that combine Trello project data with Klaviyo email performance metrics, allowing for data-driven decision-making and improved campaign strategies.

How to Build the Trello → Klaviyo Sync

In Trello, set up a webhook to listen for card movements by configuring a webhook at the endpoint https://api.trello.com/1/webhooks/. Ensure you include the action filter to capture updateCard actions.
In your webhook payload, extract the card.id, card.name, and listAfter.id to determine the new status of the card.
When a card is moved to 'Done', use the Klaviyo REST API to create a new record in a specific list. POST to https://a.klaviyo.com/api/v1/list/{list_id}/members/ with the following JSON payload: {"profiles": [{"email": "user@example.com", "project_status": "Done", "card_name": "{card.name}"}]}.
Map the Trello card details to Klaviyo profile fields to ensure accurate tracking of project statuses in your marketing campaigns.

Developer Warnings & API Gotchas

Ensure the listAfter.id value is correctly mapped to the corresponding Klaviyo list; otherwise, the data may not be inserted into the intended audience segment.
Be aware that Trello card names may contain special characters that could cause JSON parsing errors when sent to Klaviyo. Sanitize the card.name before including it in the API payload.
If multiple cards are moved simultaneously, the webhook may trigger multiple times, leading to duplicate entries in Klaviyo unless deduplication logic is implemented.
