Campaign Monitor is an email marketing platform that connects directly with Memberful. Once integrated, Memberful keeps your subscriber list automatically updated — adding new members, syncing existing ones, and sending member data as custom fields for easy segmentation and personalization. In this help article, you’ll learn how to connect Memberful to Campaign Monitor, understand how syncing works, and use custom fields to personalize and automate campaigns.

How we keep your list up to date and synced

When you first connect, Memberful imports all your existing members as subscribers and creates a list called Subscribers from Memberful in your Campaign Monitor account. This list stays automatically synced — new members are added, existing members are updated, and key details are synced as custom fields. You can use these fields to build Campaign Monitor segments. To view them, click a subscriber in Campaign Monitor to see the Memberful custom fields associated with their profile. Campaign Monitor profile Here are the custom fields Memberful continuously syncs to Campaign Monitor:
  • Active Subscription: Updated if the member has an active subscription.
  • All Access Pass: Updated if you or another team member granted an All Access Pass.
  • Plans [Your plan name]: Added if the member is subscribed to one or more plans.
  • Product [Your download name]: Added if the member purchased a download.
  • Signup Source
    • Checkout: Member signed up through the purchase form.
    • Created by Admin: Member was created manually by you or a staff member.
    • Free Registration: Member signed up through the free registration form.
    • Gift: Member received a gifted subscription.
    • Team Subscription: Member joined through a group subscription.
Members are not removed from your Subscribers from Memberful list when their subscription expires. If the member’s subscription ends, Memberful updates or removes the related custom fields. If a member changes their email address, Memberful adds the new email as a new subscriber and removes data from the old one.

Custom fields after checkout
Fields with predefined options (checkbox and dropdown) are ideal for segmenting subscribers in Campaign Monitor — for example, asking where they consume your content or which benefits interest them most. Fields with free-form answers (text and comment) are best for personalizing emails with details such as nicknames and social handles. All answers appear as custom fields in Campaign Monitor.
