How to integrate MailAdx with MailerLite

  1. 1

    Create a MailAdx publisher account

    Sign up at mailadx.com/signup and create an ad placement in the Publisher Portal.

  2. 2

    Add a custom HTML block in MailerLite

    In MailerLite's drag-and-drop editor, add a Custom HTML block where you want the ad to appear. Switch to code view to paste the MailAdx ad tag.

  3. 3

    Configure the email hash merge tag

    MailerLite supports subscriber personalization via {$subscriber_hash} or custom fields. Store the SHA-256 email hash as a custom subscriber field and reference it in your ad tag URL.

    Send a test campaign and verify

    Send a test email to yourself, open it, and confirm the ad loads. Check the Publisher Portal for the impression.
