Mailchimp – Triggers

Estimated reading time: 25 min

What will start your automation…


These Triggers will start your Flow automatically at a specific time or intervals instead of being triggered by events like Webhooks.

Keep in mind that, we have combined Mailchimp Triggers with Mailchimp Transactional Triggers (formerly Mandrill).
You can distinguish between different Trigger types by their color. Triggers associated with Mailchimp Transactional will have a yellow Mailchimp logo. To use these Mailchimp Transactional Triggers, you must first establish a connection to your Mailchimp Transactional Email. See how to create a connection here.

The Flow will initiate automatically when a webhook event is received . This means that the Flow is automated without a scheduler and will run until you deactivate the Flow manually.

Once your Flow is configured, you can test or automate it using the Run panel or by managing Triggers from the Flow Management screen.

  • Run Flow: Manually runs the Flow once using sample data. Ideal for testing logic and field mapping. See How to Run a Flow.
  • Run Scheduler: Force-runs the Trigger immediately using live input. This bypasses the recurrence rule and is useful for verifying real data mapping. Learn more in Wiresk Scheduler – The Fundamentals.

From the Trigger management panel (clock icon), you can:

  • Activate or deactivate Triggers
  • Force-run the scheduler
  • Copy Routing Keys (for HTTP Triggers)

If your Flow uses a Webhook Trigger, it runs automatically on each incoming webhook—no scheduler required. It remains active until you manually deactivate it.
