; }; [Campaign Monitor](https://www.campaignmonitor.com/a/) 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. ## Integrate Campaign Monitor In your Memberful dashboard, go to *Content → Email marketing*, then click **Connect** under Campaign Monitor. You will be redirected to Campaign Monitor to sign in and authorize Memberful to add subscribers to your mailing list. Connect to Campaign Monitor

## 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.](https://help.campaignmonitor.com/list-segmentation) To view them, click a subscriber in Campaign Monitor to see the Memberful custom fields associated with their 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. ## Send a targeted campaign To send targeted campaigns, [create a new segment](https://help.campaignmonitor.com/list-segmentation#create-a-rule) using the custom fields synced from Memberful.

## Add a referral link to your campaign If you have enabled [Memberful referrals](/discounts-and-gifting/lifecycle-discounts/offer-referral-discounts), you can add a referral link to your campaign so members can earn rewards for referring others. In your Campaign Monitor editor, go to *Insert → Custom fields → Subscribe… Memberful.* Campaign Monitor custom fields

## Create automations for segments You can use [Campaign Monitor's automated journeys](https://help.campaignmonitor.com/s/article/automated-journeys) to send event-triggered emails — such as autoresponders — to specific segments. ## Use custom field answers for segmentation and personalization You can [collect up to 5 custom fields](/configuration/feedback-and-policies/create-custom-fields/) with Memberful right after your members complete the checkout form. 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. All answers show up as Campaign Monitor custom fields

## What happens when you reconnect your email service provider? When you reconnect your integration, we'll resync your members and update the appropriate custom fields, applying them to active members and removing them from inactive ones. To avoid unintended email triggers, disable any [Campaign Monitor automated journeys](https://memberful.com/docs/newsletters/integrations/campaign-monitor#create-automations-for-segments) before reconnecting.
