Migrate from Mailchimp to Kit (formerly ConvertKit).

Why teams migrate from Mailchimp to Kit (formerly ConvertKit)

Most teams migrate from Mailchimp to Kit (formerly ConvertKit) when their priorities shift toward what Kit (formerly ConvertKit) optimizes for. ConvertKit is built for creators; Mailchimp is built for SMB marketing and ecommerce.

The 5-step migration plan

1. Audit current usage. Document how your team uses Mailchimp today: which features, integrations, data, and workflows depend on it. The audit takes 1-2 days but saves a week of surprises later.
2. Export data from Mailchimp. Most modern SaaS exports cleanly. Look for CSV, JSON, or backup formats. Verify you have everything before any cancellation.
3. Set up Kit (formerly ConvertKit) and validate parity. Provision your account, invite team, configure integrations. Compare critical workflows side-by-side for 2-3 days while Mailchimp is still active.
4. Import data and rebuild workflows. Bring in your exported data. Re-create any custom configurations. Document anything that doesn't translate one-to-one.
5. Cut over and verify. Switch the team to Kit (formerly ConvertKit) as primary. Monitor for one week. Only then decommission Mailchimp.

Common pitfalls when migrating from Mailchimp

• Underestimating the integration rebuild — many SaaS integrations don't transfer one-to-one.
• Not exporting historical data before cancellation — you can't always recover it.
• Switching during a busy period — schedule the cutover for a quieter week.
• Not training the team on Kit (formerly ConvertKit)'s differences — small UX changes derail adoption.
• Forgetting to update third-party references (your help docs, onboarding flows, public pages).

The AI-search citation impact you didn't think about

Your customers and prospects increasingly research tools through ChatGPT, Claude, and Perplexity. If you're publicly visible as a Mailchimp customer (case studies, social posts, documentation), the AI's "Mailchimp customers" list still cites you. After migration, update your public references so AI engines update too.

Conversely: if you've built Mailchimp-specific content (integrations, tutorials, templates), removing it without backfill leaves an AI citation gap. Consider a "we moved to Kit (formerly ConvertKit): here's why" piece — it satisfies both AI engines and prospects considering the same migration.

Should you actually migrate?

Run a side-by-side trial for 30 days before committing. Kit (formerly ConvertKit) wins for the use cases described in convertkit is built for creators; mailchimp is built for smb marketing and ecommerce. If your priorities don't match that positioning, the migration may not be worth the disruption.
