Builder sends each email to MailerLite Classic as a draft campaign. Pushing again updates its content. MailerLite Classic is the legacy product. Its key is separate from current MailerLite. Use the connection that matches your account.

Connect MailerLite Classic

Workspace owners and admins connect this integration.
  1. Open Integrations in Builder and choose MailerLite Classic under Email service providers.
  2. Give the connection an Account name your team will recognize, then enter the details below.
  3. Save the connection. For another account on the same platform, choose Connect another account and give it a recognizable name.
Builder connection form for MailerLite Classic

The MailerLite Classic connection form in Builder. Enter your own account details; no credentials are shown in this example.

Saved secrets are not shown again. Leave a saved secret blank to keep it, or enter a new value to replace it. Credentials saved only in the Figma plugin do not connect the Builder account. Use Where to find these in the connection panel for the provider’s setup guidance.

Export from Builder

Open an email, click Export, choose MailerLite Classic and the account, then review the dialog and confirm. The export creates a draft campaign. When updating an earlier export is offered, choose that destination or make a new copy. Check the destination after export and finish your sending setup in the platform. An export does not send a campaign. If Builder says Check your ESP before retrying, inspect the destination before exporting again. See Exporting and plans.

Email reporting in Builder

Sent count only. Its reporting period is unspecified. Subscriber counts and rates are excluded. This support is for MailerLite Classic, not current MailerLite.
  1. Open Reports → Email performance, choose a design system and click Manage insight settings.
  2. Choose this ESP account. Its reporting options load automatically.
  3. Select the account snapshot source.
  4. Click Save and load results to save your selection and queue the import. The account needs reporting permission separately from export access.
  5. Click Update now in the report for a manual refresh, or enable Sync ESP results and save for refreshes every six hours.
Use results in AI assistance is a separate, default-off switch. Reporting does not access or change contacts, recipient events or clicked destinations. Reports remain scoped to the authorized workspace and design system. See Email insights and reporting for date windows, unknown metrics, AI use, privacy and deletion controls.

Troubleshooting

  • Connection rejected: check the credentials and any region or endpoint against the account you want to use. Update saved secrets in Integrations if they have changed.
  • Wrong destination: check the selected account before exporting or choosing a report source.
  • Exports work but reporting fails: save your source selection and run Check reporting access. Check reporting permissions and the source ID. Do not grant contact access to work around a reporting limitation.
