How to import Mailchimp list into an existing Klaviyo list?

Hi there. Using the Mailchimp integration, is there a way to import a list from Mailchimp into an existing Klaviyo list? I’m trying to maintain a single list, and don’t want to deal with merging a new list into our main list.

I tried unchecking the “Create Klaviyo lists from Mailchimp lists” checkbox in integration settings, but doesn’t seem to work. Probably this feature was for intended for something else. Any ideas would be greatly appreciated. Thanks, –oo

    Hello @Doubleo,

    Great question! Having a single list is highly beneficial and great practice!

    As mentioned in the How to Migrate from MailChimp article, the setting of Create Klaviyo lists from MailChimp lists is meant to sync all your existing MailChimp lists to Klaviyo as they are and would not sync them to an existing Klaviyo list. To import a MailChimp list to an existing Klaviyo list, I would suggest manually exporting the MailChimp list and importing it into your desired Klaviyo list. 

    After exporting your list from MailChimp, you can import it into your desired Klaviyo list by following the instructions found in the How to Add Subscribers to an Existing List article. If you were having trouble in your import, I would also recommend taking a look at our How To Troubleshoot List Imports article. 

    Thanks for being a member of the Klaviyo Community!

    To import a Mailchimp list into an existing Klaviyo list, Skyvia can be a practical solution. It allows for data import and synchronization between Mailchimp and Klaviyo. You can map the Mailchimp list data to your existing Klaviyo list, ensuring seamless integration and avoiding the creation of a new list. Skyvia's intuitive interface facilitates this process, making it easy to maintain a single, consolidated list in Klaviyo without manual merging.

    Hi, great thread - I have a related yet slightly different question. I’m using Klaviyo’s Mailchimp integration to migrate over to a new Klaviyo account, and I checked the box to create Klaviyo lists from Mailchimp lists in the settings. I see that it created a list and just named it the company name from the Mailchimp account. If I change the name of that list in Klaviyo and I still have Mailchimp connected, will Mailchimp still sync to that list? We’ll have a bit of lag time updating our website form over to Klaviyo, so still want to keep the integration connected for a couple of days to allow form submissions that go to Mailchimp to still pass through to Klaviyo. Thanks!
