How to migrate from MailerLite Classic to the new MailerLite

If you're using MailerLite Classic, you can now take advantage of our migration tools to help you transition to the new MailerLite.

This guide will help you set up a brand new account with the updated version of MailerLite and transfer over your data. Please note, a paid plan on MailerLite Classic will not be migrated over or applied in any way to the new account. It is up to you to manually cancel your MailerLite Classic plan to avoid double billing. See our guide to plan and billing for instructions on how to cancel your plan.

To migrate from MailerLite Classic to the new MailerLite:

1. In your MailerLite Classic account, navigate to the Integrations page.

2. Under Developer API, click Use.

3. Copy the API key to your clipboard (you'll need it a bit later).

4. Then click the SSO icon. The account should be created from this icon inside your MailerLite Classic account, as it allows you to easily switch between the two versions.

5. Select MailerLite (new version) on the left.

6. If you already have an account created with the new MailerLite, you’ll see it listed on the next page. If not, you can create one by clicking New account. You may also see this screen, where you can enter your password to create a new account.

7. Follow the prompts to give it a name, and enter the necessary information.

8. Once you reach the dashboard, you will find the option to migrate information from your MailerLite Classic account.

9. Click Migrate account.

10. Paste the API key from your MailerLite Classic account into the corresponding field.

11. Click Confirm & migrate.

That’s it! Your account will automatically be approved, and the following account information will be migrated to your new account:

• Company details: All company details including account name, billing information and other necessary metadata will be transferred to your new MailerLite account

• Default settings: All sender details, logos, unsubscribe disclaimers and other default account settings will be applied to your new account

Sending Domains

The new version of MailerLite uses different DNS records to authenticate your sending domains. This means that if you have authenticated domains in MailerLite Classic, you will need to update the records in your DNS settings. To do this:

1. Go to Account Settings.

2. Click the Domains tab.

3. Under Sending domains, you will see the domains that were transferred over from your MailerLite Classic account. Under Authentication, click the Authenticate button to view the DKIM and SPF records.

4. Log into the DNS settings for your domain, which will be located in your domain host (outside of MailerLite).

5. Replace the previous MailerLite DKIM and SPF records with the updated records.

   The DKIM record should be CNAME type.

   The SPF record should be TXT type.

For more information on authenticating your domain, see our guide on how to verify, authenticate, and align your domain.

Custom Domains

DNS settings for custom domains being used for websites and landing pages will also need to be updated manually in your hosting provider. After the site has been migrated (instructions below) check the custom domains or subdomains that have been transferred over under the Sites section. Click Manage DNS to view the updated records.

The previous MailerLite Classic records will need to be replaced with the new records in the DNS panel.

The new MailerLite allows one account user on the free plan. If you have multiple account users on MailerLite Classic, you will need to upgrade to a paid plan in the new MailerLite in order to add more than one user to your account.

Integrations connected to your MailerLite Classic account will not automatically migrate to the new MailerLite.

The new MailerLite uses different API information to integrate with other applications. This means, any integration that is currently connected with your MailerLite Classic account will need to be re-installed using the corresponding integration for the new version.

For example, if you were previously using the MailerLite Classic > Zapier integration, you would need to replace it with the new MailerLite > Zapier integration.

Other common integrations that would need to be updated when switching to the New MailerLite are:

• Shopify for MailerLite Classic with Shopify for New MailerLite

• WooCommerce for MailerLite Classic with WooCommerce for New MailerLite

Once you have upgraded to a paid plan in MailerLite, you can quickly and easily migrate all your subscribers, custom fields and subscriber groups from MailerLite Classic. On the free plan, you have the option to migrate a subset of 1000 subscribers for free, so you can test the migration tools and the new account before upgrading for full access.

Spam complaints, as well as unconfirmed, unsubscribed and bounced subscribers, will also be migrated into their corresponding folders.

To migrate subscribers from MailerLite Classic to MailerLite:

1. From your new MailerLite account dashboard, navigate to the Account settings page.

2. Select the Migration tab.

3. Under Migration details, you will find Account details and Subscribers. Click the Proceed button next to Subscribers.

4. Click Start migration →.

• Templates migration will need to be done before migrating automations.

• Automation history and automation activity will not be migrated along with the workflows.

• Old "autoresponders" will not be migrated. These should first be updated to automations in MailerLite Classic, then they can be migrated to the new MailerLite. 

• New subscribers will start the automation in the new account from the beginning. However, subscribers who were active in the Classic automation will not be taken to the same step in the workflow once it has been migrated. These subscribers will need to complete the workflow in MailerLite Classic.

2. Confirm the migration by clicking Start migration →.
