Migration guide
MailerLite → Mailchimp
Inverse of the long-standing mailchimp-to-mailerlite cost-driven migration path. MailerLite is the friendly, simpler, cheaper-at-low-volume ESP; Mailchimp is the bigger-ecosystem, more-recognized, broader-feature-surface vendor. At equivalent paid tiers the cost is roughly even (MailerLite Advanced $20 vs Mailchimp Standard $20 at the 500-contact anchor), so this is rarely a cost migration. Move when stakeholder pressure for a brand-name vendor is real, when MailerLite's intentionally-simple product surface no longer fits the sophistication you've grown into, when you need a customer-journey builder with broader trigger taxonomy than MailerLite's automation builder, or when integration-ecosystem breadth has become load-bearing.

When this migration makes sense
- Stakeholder approval depends on a brand-name vendor. Intuit-owned Mailchimp carries weight in procurement reviews, agency proposals, and stakeholder presentations that an independent vendor like MailerLite doesn't carry by default.
- You've outgrown MailerLite's intentionally-simple product surface. Multi-trigger automations, predictive segmentation, multivariate testing on the journey level, and built-in lightweight CRM features are all native to Mailchimp; in MailerLite they're either gated to Advanced ($20/500 contacts) or absent entirely.
- Integration ecosystem breadth matters. Mailchimp's connector list spans nearly every CMS, CRM, payment processor, e-commerce platform, customer-service tool, and analytics vendor. MailerLite has the e-commerce essentials but the long tail is shorter.
- You need a customer-journey builder with broader trigger taxonomy: signups, purchases, content views, custom-event triggers, plus the time-delay and conditional-branching primitives MailerLite has but with more depth.
- You're already in the Intuit ecosystem (QuickBooks for accounting, Mailchimp for marketing) and want consolidated billing / unified login / cross-product reporting.
When it doesn't
- Cost-sensitivity at higher subscriber volumes. Past 10,000 contacts Mailchimp's per-500-contact pricing climbs faster than MailerLite's; you'll pay a premium for the brand and ecosystem. Run the math at YOUR contact count before committing.
- MailerLite's bundled website builder is load-bearing. MailerLite ships a website + blog + landing-page builder included in every paid tier; Mailchimp's website builder exists but is functional rather than polished, and isn't the core product. If you'd lose hosted content by leaving, plan an alternate host (Webflow, WordPress) BEFORE migrating.
- Nonprofit pricing is the dominant cost driver. MailerLite's 30% nonprofit discount is self-serve; Mailchimp's is approval-gated and slower to apply. The structural friction matters for small nonprofits.
- MailerLite Free's 500 subscribers / 12,000 sends covers your current usage. Mailchimp Free is 250 subscribers / 500 sends, substantially tighter. Migrating just to land back on a free plan that doesn't fit will force an unintended paid upgrade.
- Simplicity is a feature for your team. MailerLite's smaller product surface area is the point for many operators; Mailchimp has more buttons and more options and more places to get lost. If your team's complaint with MailerLite isn't 'we need more features,' don't migrate.
What you lose by leaving MailerLite
- 30% self-serve nonprofit discount on paid plans. Mailchimp's nonprofit pricing is approval-gated and slower to apply.
- MailerLite Free's 500 subscribers and 12,000 sends/month. Mailchimp Free is 250 subscribers and 500 sends/month, substantially tighter.
- Bundled website + blog + landing-page builder included in every paid tier. Mailchimp has landing pages but the website-builder story is shallow.
- 10% honest annual-billing discount applied across every paid tier. Mailchimp's annual discount is 15-20% but with stricter terms.
- Cleaner editor UX. MailerLite's drag-drop editor is one of the more polished in this category; Mailchimp's is functional but heavier.
- 30% recurring affiliate commission via Tapfiliate, if you're a MailerLite affiliate. Mailchimp doesn't run an affiliate program (Experts directory only).
What you gain with Mailchimp
- Largest integration ecosystem in the email-marketing category. Mailchimp connectors exist for nearly every CMS, CRM, payment, service, and analytics tool.
- Customer-journey builder with broader trigger taxonomy. MailerLite's automation builder is sequence-shaped; Mailchimp's customer-journey builder branches on more event types and supports deeper conditional logic.
- Predictive segmentation on Premium ($350/mo at 10k+ contacts). MailerLite tops out at multivariate testing on Advanced; predictive AI segmentation isn't a feature.
- Built-in lightweight CRM for B2B-nurture workflows. Contact-level engagement timeline, deal tracking (basic), and meeting-booking integration all native.
- Brand-name vendor recognition. Intuit ownership carries weight in procurement reviews, agency proposals, stakeholder approvals.
- Multi-tier plan ladder ($13 Essentials / $20 Standard / $350 Premium) gives more granular cost control across small / mid / large contact volumes vs MailerLite's two-paid-tier shape ($10 / $20 / Enterprise).
- Mandrill for transactional email available as a Mailchimp add-on if you want to consolidate transactional and marketing email under one account roof.
Plan mapping at the entry paid tier
The lowest non-free, non-custom tier on each side. Use this for the "if I'm on $X with MailerLite, what's the equivalent on Mailchimp?" gut check.

|---|---|---|
| Contacts | 500 subscribers (anchor; scales up) | 500 contacts (anchor; scales up) |
| Emails / month | Unlimited | 5,000 sends (10x contacts) |
| Team seats | 3 | 3 |
| Automations | · | 4 flow steps |

Step-by-step migration
- 01
Export your list from MailerLite
Pull a fresh CSV of every active subscriber. Capture the fields you actually use downstream: email is required, name is standard, signup date and tier (free/paid) are useful when MailerLite provides them.
- 02
Provision Mailchimp
Sign up, set sender identity, and verify your sending domain (DKIM, SPF, DMARC). Do this before importing the list; sending from an unverified domain is the single fastest way to land in spam at the moment of cutover.
- 03
Import the list and map fields
Upload the CSV. Map email + name + any custom fields. Decide whether to import as one list or split into segments/tags. MailerLite-style organization rarely maps 1:1, so plan the split before the upload, not after.
- 04
Rebuild automations and templates
Mailchimp's automation builder is structurally similar but won't import MailerLite's flows directly. Rebuild only what you actively use; the move is a chance to delete the unused ones rather than lift-and-shift dead infrastructure.
- 05
Send a test broadcast
Pick a small segment and send a real broadcast (not just a preview). Verify deliverability, link clicks, and unsubscribe flow. If anything's off, you find it before the announcement, not after.
- 06
Announce the move and cut over
Send your last broadcast from MailerLite announcing the new sender domain and what to expect. Cut over DNS and sending from Mailchimp on the same day, not staggered. A dual-send week creates more confusion than it prevents.
MailerLite-to-Mailchimp specific gotchas
Universal steps cover most of the work. These are the failure modes unique to this exact pair.
-
#1
Subscriber import: MailerLite exports CSVs with subscriber + group + segment data. Mailchimp imports into audience(s) with tags. Audit how you currently use MailerLite groups; many group structures map cleanly to Mailchimp tags (multiple groups per subscriber), but some need to become separate Mailchimp audiences (which counts separately for billing). Plan the audience taxonomy before importing.
-
#2
Custom-fields rebuild: MailerLite's custom-field types (text, number, dropdown, datetime, image, boolean) don't all 1:1 map to Mailchimp's. Image fields in particular don't transfer. Audit which custom fields drive automation logic; rebuild only the load-bearing ones rather than every field.
-
#3
Automation rebuild: MailerLite's automation builder is sequence-shaped with time-delay plus tag/group triggers. Mailchimp's customer-journey builder is structurally similar but the trigger taxonomy and conditional-branch primitives differ. Plan to rebuild flows from scratch with the equivalent Mailchimp triggers; don't expect import.
-
#4
Website / landing-page migration: if you've built MailerLite-hosted pages or sites, those don't transfer. Either ship them on a separate host (Webflow, WordPress, Astro / Eleventy) BEFORE deactivating MailerLite, or re-author them in Mailchimp's landing pages (which lack MailerLite's bundled-website depth). Don't underestimate this lift; it can take 2-4 weeks for a content-heavy site.
-
#5
Email-template differences: MailerLite's drag-drop editor produces structurally different HTML than Mailchimp's. Templates that render cleanly in MailerLite may break visually in Mailchimp's editor. Re-author the 5-10 templates you actually use rather than trying to paste-in-port a template library.
-
#6
Sender-domain DNS staggering: MailerLite issues mlsend.com / k.mlsend.com TXT records; Mailchimp uses mc.us<region>.list-manage.com / k1._domainkey.<domain> patterns. Add Mailchimp's records alongside MailerLite's, verify Mailchimp, warm the new sender on a percentage of traffic for 7 to 14 days before flipping the from-address. Don't hard-cut a production sender.
Common questions
- Is Mailchimp cheaper than MailerLite?
- Both start at the same headline price (Free). The reason to migrate is the pricing model and feature scope, not the entry-tier number.
- Will I lose subscribers in the move?
- Email lists transfer as raw addresses; subscriber relationships transfer with you because the addresses haven't changed. What you can lose: re-engagement (some readers won't notice the new sender domain immediately), paid subscriptions if MailerLite handles billing differently from Mailchimp (the gotchas above call out the specific cases), and any "engagement" or warmth signals that MailerLite's deliverability inferred from your sending history. Plan a clear announcement and a deliverability warm-up week.
- How long does the migration take?
- For a list under 10,000 subscribers, a clean migration is one focused week: domain setup and verification, list import, automation rebuild, test broadcast, announcement, cutover. Larger lists or complex automations can stretch to 2 or 3 weeks. The constraint is rarely the import itself; it's the deliverability warm-up and the time to rebuild flows you actually depend on.
- Are MailerLite and Mailchimp direct competitors?
- Yes. Both are primarily email marketing tools, which is why this is a defensible head-to-head migration rather than a cross-category consolidation.
- Where can I see MailerLite vs Mailchimp side-by-side?
- The /compare/mailchimp-vs-mailerlite page on TierGauge shows side-by-side plans, headline pricing, included features, and limit comparison at the entry paid tier. This migration guide is the long-form decision narrative; the compare page is the data-only dashboard.
