MARKETING AUTOMATION · MIGRATION GUIDE

Switching from Klaviyo to Mailchimp

Moving from Klaviyo to Mailchimp means exporting your profiles and list data manually, since Mailchimp has no dedicated Klaviyo connector the way Klaviyo has one for Mailchimp.

Quick verdict: This move mostly makes sense for cost reasons – smaller or non-ecommerce teams downsizing from Klaviyo’s active-profile pricing to Mailchimp’s cheaper entry tiers – but you’ll lose flow logic and revenue-attribution reporting in the process.

Why teams switch from Klaviyo to Mailchimp

Lower cost at smaller list sizes

For non-ecommerce senders or smaller lists, Mailchimp’s Essentials and Standard tiers are generally cheaper than Klaviyo’s equivalent active-profile pricing.

Simpler interface for non-technical teams

Mailchimp’s campaign and automation builders are widely considered easier to pick up for marketers who don’t need Klaviyo’s deeper conditional logic.

Broader all-in-one marketing toolkit

Mailchimp bundles landing pages, social ads, and a built-in CRM-lite layer that some teams prefer over stitching together point tools around Klaviyo.

How to migrate your data

There’s no native Klaviyo-to-Mailchimp sync, so this migration is a manual export/import process from the Klaviyo side.

StepWhat happens
1. Export your Klaviyo profilesFrom Klaviyo’s Lists & Segments, export each list or segment you want to keep as a CSV of profile data.
2. Export engagement and consent dataPull subscription status and consent timestamps as well, since Mailchimp requires clear opt-in records for compliance.
3. Create matching audiences in MailchimpSet up corresponding audiences in Mailchimp and import the CSVs, mapping fields like email, name, and custom properties.
4. Rebuild segments as Mailchimp tags or groupsKlaviyo segments don’t map directly to Mailchimp, so recreate your key segments manually using Mailchimp’s tags, groups, or conditional segments.
5. Recreate flows as Mailchimp automationsManually rebuild each Klaviyo flow (welcome series, abandoned cart, post-purchase) as a Mailchimp customer journey, since flow logic does not export or import.
6. Update store integrations and signup formsReconnect your ecommerce platform to Mailchimp and repoint website signup forms before disconnecting Klaviyo.
What Mailchimp’s importer doesn’t handle: Flows, segments built on behavioral logic, and email templates all need to be rebuilt by hand in Mailchimp – CSV export/import only carries over static profile data, not the automation or targeting logic behind it.

Pricing during the transition

Mailchimp is generally the cheaper of the two at low-to-mid contact volumes, which is often the main driver for this switch.

PlanKlaviyoMailchimp
Free plan$0 (up to 250 profiles, Klaviyo)$0 (up to 250 contacts, Mailchimp)
Entry paid tier (~500 contacts)Email plan around $20/monthEssentials from around $13/month
Mid tier (~1,000 contacts)Email plan around $30/monthStandard from around $20/month

Mailchimp’s Standard and Premium tiers add per-contact costs at scale too, so re-check pricing at your specific list size before assuming Mailchimp stays cheaper as you grow; figures reflect list pricing as of September 2026.

Frequently Asked Questions

Is there a native Klaviyo-to-Mailchimp importer?

No – unlike Klaviyo’s built-in Mailchimp sync, Mailchimp has no dedicated Klaviyo connector, so this is a manual CSV export/import migration.

Will my Klaviyo flows work in Mailchimp?

No, flow logic doesn’t transfer at all – you’ll need to manually recreate each automation as a Mailchimp customer journey.

What happens to my Klaviyo segments?

Behavioral segments don’t export as logic, only as static snapshots of who’s currently in them, so you’ll need to rebuild the underlying rules in Mailchimp.

Why would someone downgrade from Klaviyo to Mailchimp?

Usually cost – Mailchimp tends to be cheaper for smaller lists or teams that don’t need Klaviyo’s ecommerce-specific behavioral targeting.

Can I keep both tools running during the switch?

Yes, and it’s recommended – run Mailchimp in parallel for a full send cycle before cancelling Klaviyo so you can confirm deliverability and automations are working.
