Klaviyo + Mailchimp

Klaviyo + Mailchimp integrations

Add new Mailchimp subscribers to Klaviyo

Moving contacts from one platform to another is a chore. This integration helps. It moves data between Mailchimp and Klaviyo so you don't have to. Once active, it turns each new subscriber on Mailchimp into a contact on Klaviyo. You'll be able to manage all your leads from your CRM.

When this happens...
New SubscriberTriggers when a new subscriber is added to an audience.
