MIGRATION GUIDE

Switching from Mailchimp to Moosend

Moosend is one of the few destinations that reads a Mailchimp account directly instead of making you shuttle CSVs, which is why this is one of the shorter migrations in the category.

Where our research ends. We keep a full hand-researched dossier on Moosend. We do not keep one on Mailchimp, so you will not find us characterising their pricing or their product here — that would be exactly the invented-authority thing we complain about in other people’s comparison pages. What follows is what our research says about Moosend, and what Moosend’s own documentation says about moving to it. Check Mailchimp’s current terms yourself before you cancel anything.

Is Moosend the right destination for you?

Our dossier is blunt about this. Moosend is genuinely best for small businesses and marketers who want affordable email marketing and automation with a low entry price, a real free trial and a clean drag-and-drop builder. On price: (2026) Free trial.

The honest knock: The friendly $7-9 headline is the entry rate at a small list size — Moosend's email pricing scales with your subscriber count, so as your list grows the monthly bill climbs with it, and the lowest rate assumes annual billing.

How the migration actually works

These steps are summarised from Moosend’s own public documentation — we have not invented or embellished a single one. Read the source before you start, because vendors change their import tooling more often than they change their pricing page: Moosend docs — Import your Mailchimp campaigns and email lists →

Step 1. Open the Mailchimp Synchronizer

In Moosend, go to More › Integrations, find Mailchimp Synchronizer and click Select. This is a first-party Moosend integration, not a third-party connector you pay extra for.

Step 2. Connect with your Mailchimp API key

Paste your Mailchimp API key and click Connect Account. Generate the key inside Mailchimp rather than reusing an old one, so you can revoke it cleanly once the move is done.

Step 3. Choose what comes across

On the Campaign Selection tab, pick the campaigns you want synchronised. To bring your verified senders too, tick the Yes checkbox for campaign senders.

Step 4. Let the sync finish before you rebuild anything

The synchroniser pulls campaigns, senders, email lists, unsubscribe lists and custom fields. Moosend's own docs warn that this takes a while on a large list — don't start rebuilding automations in parallel until it has settled.

What the docs quietly admit

Every migration has friction. These are the documented ones — the things worth knowing before you start, not after:

When not to switch

The most useful thing we can tell you is when to stay put. Skip this migration if you run a very large list where per-subscriber pricing adds up, or you only need transactional/API email — a developer-focused sender is cheaper for that. Beyond that: if your current setup works, your list is healthy and nobody on your team is complaining, a migration buys you a week of admin and a fresh set of unknowns. Switch because something specific is broken or expensive — a deliverability problem you can name, a bill that has outgrown the value, a feature you genuinely cannot get — not because a comparison page told you the grass was greener.

Questions people actually ask

Is it hard to migrate from Mailchimp to Moosend?

Moosend is one of the few destinations that reads a Mailchimp account directly instead of making you shuttle CSVs, which is why this is one of the shorter migrations in the category. The full step-by-step is on this page, summarised from Moosend's own documentation.

Will I lose data moving from Mailchimp to Moosend?

Large lists take a meaningful amount of time to synchronise; Moosend flags this explicitly rather than promising an instant move.

When should I not switch to Moosend?

Skip it if you run a very large list where per-subscriber pricing adds up, or you only need transactional/API email — a developer-focused sender is cheaper for that. A migration is only worth it when the tool solves a problem that is already costing you real hours or revenue.

What is the honest downside of Moosend?

The friendly $7-9 headline is the entry rate at a small list size — Moosend's email pricing scales with your subscriber count, so as your list grows the monthly bill climbs with it, and the lowest rate assumes annual billing.
