A Primer on Unito’s Mailchimp Integration

This is a lite integration, which means there are a few things you need to know before you start using it.

Included in this article:

How does this lite integration work?

When an integration from our upcoming integrations page gets enough interest, we start working to add it to our suite. The first step is working towards a lite version of the integration so you can get access to it earlier. That gives you the chance to send us your feedback and lets us tune it to better fit your use case.

Got feedback? Submit a Unito feature request to let us know what you'd like to see in the next update to our Mailchimp integration.

Supported fields and other features

Our lite integrations don't usually support as many fields as other integrations. Here are the fields you can sync with our Mailchimp integration, along with the fields you can use in rules.

Quick definitions:

    • One-Way: Changes to the Mailchimp field will appear in the other synced field but not vice versa.
    • Two-Way: Changes to either synced field will appear in the other.
    • Rules: This Mailchimp field can be used as a trigger in your rules to filter work items from syncing with Unito.

What counts as an item in sync?

Unito counts every synced Mailchimp contact as an item in sync.

Limitations and other considerations

Because this is still a lite integration, there are some things you won't be able to do.

  • Syncing addresses: You can sync addresses from Mailchimp to other tools, but you'll need to make sure you properly map the Street, City, State/Province/Region and Postal/Zip fields.

  • Syncing the Birthday field: This field can only be synced from Mailchimp to other tools.

  • Two-way flows: You can build two-way flows when syncing contacts to and from Mailchimp. When syncing other work items, however, you can only set up a one-way create two-way update flow.

  • The Opt-In field: When a Unito flow creates a new contact in Mailchimp, the Opt-In field will be automatically checked.

  • Contact merging: You can merge contacts in Unito to prevent your Mailchimp contacts from getting duplicated as you sync them.
