Switching from Mailchimp to Moosend saves most businesses 45% on their monthly email bill — approximately $1,626/year on an average list size — and eliminates the billing structure that inflates Mailchimp costs beyond the headline price. Moosend’s native Mailchimp Synchronizer automates most of the migration: contacts, tags, segments, and unsubscribers transfer automatically. This guide covers what’s automated, what you’ll rebuild, and exactly how to execute the switch without losing a subscriber.

If you're here, you've already done the math and the number doesn't look good. Mailchimp used to be the obvious choice for email marketing. It isn't anymore — and the people leaving aren't abandoning ship impulsively. They're responding to a platform that has methodically repriced itself out of value territory since Intuit took over.

This guide walks you through the complete migration from Mailchimp to Moosend: what moves automatically, what you'll need to rebuild, and exactly how to execute the switch without losing a subscriber or breaking your automations.

Section 1: Why Mailchimp Users Are Leaving in 2026

Intuit acquired Mailchimp in 2021 for $12 billion. Since then, the product has followed a predictable post-acquisition arc: price increases, free tier cuts, and a shift toward monetizing existing users rather than growing them.

The numbers tell the story clearly:

The free tier was gutted. Pre-acquisition, Mailchimp's free plan covered 2,000 contacts — workable for early-stage businesses. Today it allows 250 contacts and 500 emails per month. That's not a free plan. That's a trial with no clock.

Paid plans start at $20/month and price-escalate fast. Mailchimp Standard is $20/month for 500 contacts — and that price jumps sharply as your list grows. A 5,000-contact list runs $75/month on Standard. Hit 10,000 contacts and you're looking at $130+/month. The send limits add another layer of friction, capping how often you can reach your own list.

Duplicate contacts count against your billing total. If the same email address exists in two audiences, Mailchimp charges you twice. This isn't an edge case — anyone managing multiple segments or importing contacts from different sources will hit this. It's a billing structure that punishes growth.

Beyond pricing, the product itself has changed. Mailchimp's interface has grown more complex with each update — more menus, more upsells, more friction between you and a sent email. Features that used to be included in base plans have been quietly shifted into higher tiers. Customer support response times on lower plans have stretched out. The platform is optimizing for its enterprise segment, and if you're not in that segment, you feel it.

The frustration is real, and it's earned. Moving to Moosend isn't a panic move — it's a calculated one.

Section 2: Why Moosend Is the Right Move

Moosend is the platform that competes directly with what Mailchimp used to be: full-featured automation, real segmentation, and pricing that doesn't punish you for growing your list.

Side-by-Side Pricing

Subscribers Mailchimp Standard Moosend Pro Annual Savings
500 $20/mo $7/mo ~$156/yr
2,000 $45/mo $9/mo ~$432/yr
5,000 $75/mo $32/mo ~$516/yr

Across an average list size, users switching from Mailchimp to Moosend save approximately 45% on their monthly bill — around $1,626/year. Choose annual billing and that number climbs to roughly $2,355/year with the additional 20% discount applied.

What the Numbers Actually Mean

To put the $1,626/year savings in concrete terms: a business on Mailchimp Standard with a 5,000-contact list pays $75/month — $900/year. The same list on Moosend Pro runs $32/month — $384/year, or $307 annually with annual billing applied. That's nearly $600/year on one list size alone. Scale to 10,000 contacts and the gap widens further.

This isn't a promotion-week discount. It's the base pricing difference between two platforms targeting the same customers at very different margins.

What You're Actually Getting

The migration tool alone eliminates the biggest hesitation most people have about switching. You don't need to manually export and re-upload thousands of contacts. The Synchronizer handles it automatically.

Section 3: What Transfers and What You'll Rebuild

The Mailchimp Synchronizer handles more than most people expect — but it doesn't handle everything. Here's an honest breakdown of what moves automatically versus what requires manual effort on your end.

What Transfers (via Synchronizer) What You'll Rebuild
✅ Contacts and subscriber data ❌ Email templates
✅ Tags and segments ❌ Automation workflows
✅ Campaigns (imported) ❌ Third-party integrations
✅ Unsubscribe lists ❌ Landing page embed URLs

The rebuilds aren't as bad as they look. Most businesses have two or three core automation sequences — a welcome series, maybe a post-purchase flow or re-engagement sequence. Moosend's automation builder is visual and straightforward, using the same trigger-condition-action logic as Mailchimp's Customer Journey builder. If you know what your Mailchimp automations do, you can rebuild them in Moosend without having to redesign the strategy from scratch — just the execution environment changes.

Email templates are the one area that requires genuine effort. Moosend's template library is smaller than Mailchimp's, so if you've heavily customized your Mailchimp templates, plan to spend time recreating them in Moosend's editor or working from their base templates.

One critical step before you do anything else: Export your Mailchimp campaign analytics before you cancel your account. Once you cancel, you lose access to your historical open rates, click rates, and campaign data. There is no recovery option. Even if you never look at these numbers again, having them is better than losing them permanently.

A note on integrations: if you're using Mailchimp's native integrations with tools like Shopify, WooCommerce, or your CRM, those connections will need to be rebuilt in Moosend. Moosend has native integrations for the most common platforms, but if you're using something niche, check their integrations list before committing — or plan for Zapier as a bridge layer.

Most migrations complete in under one hour when using the Synchronizer. The rebuilding of automations is typically done in the first week. Running parallel for 1–2 weeks before cancelling Mailchimp is the cautious approach — and the one we recommend.

Section 4: Step-by-Step — Export Your Mailchimp Data

Even with the Synchronizer doing most of the work, exporting your data first gives you a clean backup and makes cleanup easier. Do this before you touch Moosend.

  1. Log into Mailchimp → Audience → Manage Audience → Export Audience. This downloads your full subscriber list as a CSV, including all custom fields and tags.

  2. Download the CSV and save it somewhere you can find it. Name it clearly: mailchimp-export-YYYY-MM-DD.csv. You may not need it, but you'll want it if the Synchronizer misses any custom fields.

  3. Clean the export before using it. Remove contacts with a status of "Unsubscribed" or "Cleaned" from your import list. Importing unsubscribed contacts and emailing them is a CAN-SPAM violation. Don't do it.

  4. Export your unsubscribe list separately. In Audience → Manage Contacts → Unsubscribes, export that list independently. You'll import it into Moosend as a suppression list so those contacts are automatically excluded from all campaigns.

  5. Screenshot your best campaign stats now. Open rates, click-through rates, revenue per email — capture anything you'll want to reference later. You lose this data when you cancel.

  6. If you have multiple Mailchimp Audiences, export each one separately. Each audience is a distinct list. Run this export process for every audience you plan to migrate.

Once you have your exports saved and your suppression list ready, you're set to move into Moosend.

Section 5: Step-by-Step — Import to Moosend with Mailchimp Synchronizer

This is where most of the work happens — and most of it is automated.

  1. Create your Moosend account. The 30-day free trial requires no credit card. Start at moosend.com and set up your account before doing anything else.

  2. Navigate to Account Settings → Integrations → Mailchimp Synchronizer. It's listed under the integrations panel in your account settings. Not under "Import" — under Integrations.

  3. Authorize your Mailchimp account. You'll be prompted to log in to Mailchimp and grant Moosend read access. This is a standard OAuth flow. Moosend does not store your Mailchimp password.

  4. Select what to import. The Synchronizer lets you choose: campaigns, audiences, subscribers, and unsubscribers. Select all of them unless you have a specific reason to exclude something.

  5. Run the sync. Moosend pulls everything automatically. Depending on your list size, this takes between a few minutes and 15–20 minutes for very large lists. You'll receive a confirmation when it's complete.

  6. Import your CSV manually if needed. If you have custom fields that the Synchronizer didn't carry over cleanly, use the standard CSV import in Moosend → Audience → Import Contacts. Map your columns to the correct Moosend fields during import.

  7. Set up domain authentication — SPF and DKIM — before you send anything. This is non-negotiable. Without proper authentication, your first sends from a new sending domain will suffer deliverability problems. Moosend has a step-by-step guide under Account Settings → Senders → Domain Authentication. Your domain registrar or DNS host is where you'll add the required records.

The Synchronizer does the heavy lifting. Steps 6 and 7 are the ones most people skip and then wonder why their first campaign underperforms.

Section 6: Test Before You Cancel

Don't cancel Mailchimp the day you finish importing to Moosend. Run them in parallel for one to two weeks. Here's the checklist before you pull the plug on Mailchimp.

Rebuild your automations in Moosend first. Start with your welcome sequence — it's the highest-traffic automation most businesses run. Map each Mailchimp automation step to Moosend's visual workflow builder. The logic transfers directly; only the interface is different.

Rebuild in priority order:

  1. Welcome sequence (new subscriber onboarding) — this fires every time someone joins your list; it can't be down
  2. Post-purchase follow-up (if e-commerce) — revenue-generating; high priority
  3. Re-engagement sequence — important but can wait a week
  4. Any other active flows — assess volume and revenue impact before prioritizing

Warm up your sending reputation. Moosend is a new sending domain for your recipients' inboxes. For the first two weeks, send to smaller segments — your most engaged contacts first. Gradually increase volume. This is standard practice any time you switch ESPs and it directly affects your open and deliverability rates.

Send a test email to yourself before any live sends. Check rendering across email clients (Gmail, Outlook, Apple Mail), verify links are working, and confirm your unsubscribe link is functional. Moosend's spam analysis tool under campaign preview will flag deliverability issues before you send.

Update your website opt-in forms. Mailchimp embed codes don't work in Moosend. Swap your website signup forms to Moosend's form embed codes before you cancel. This is one of the most commonly missed steps — people cancel Mailchimp and then realize their homepage signup form is still pointing to a dead list. Test your form submission after switching to confirm new subscribers are landing in Moosend. If you use a WordPress plugin or third-party form tool like Gravity Forms, Elementor, or OptinMonster, check whether Moosend has a native integration or whether you'll need Zapier as a bridge.

Cancel Mailchimp only after:

When those boxes are checked, you're done. Cancel Mailchimp, redirect your budget, and you're running a cleaner, cheaper email stack.

Conclusion

Switching email platforms feels bigger than it is. With Moosend's Mailchimp Synchronizer, the actual migration — contacts, tags, segments, unsubscribers — is automated. The manual work is rebuilding automations and templates, which for most businesses is a few hours of focused effort spread across a week.

The result: a platform that delivers the same core functionality at 45% less cost, with no send caps, no duplicate contact billing, and no free tier that expires after 250 subscribers.

The $1,626/year average savings is the headline number. The more durable win is operating on a platform that isn't actively working against your budget as your list grows. Moosend's pricing structure — billing on engaged subscribers rather than total contacts — means your costs don't spike simply because you've accumulated cold contacts over time. That's a meaningfully different relationship between usage and billing than what Mailchimp offers.

For businesses that send consistently and want reliable automation without enterprise pricing, the case for switching is straightforward. The migration path is well-defined, the tooling is built in, and the first month is free to validate the platform before you spend a dollar.
