Loyalty programs are only effective when customers remember the value they have earned.

A customer may earn wallet coins, generate a coupon, refer a friend, receive a reward, or become eligible for an expiry reminder. But if those actions stay inside the loyalty platform and never reach the customer's inbox, the moment can go unnoticed.

That is where the Nector + Mailchimp integration helps.

The integration allows merchants to send selected customer activity events from Nector into Mailchimp. These events can then be used to trigger Mailchimp customer journeys and automated emails. Nector's Mailchimp help guide explains that events can be sent to Mailchimp when certain actions happen in Nector, such as when wallet coins are rewarded or when a customer uses wallet coins to create a discount or coupon code.

For Shopify, DTC, ecommerce, and omnichannel brands, this creates a stronger connection between loyalty activity and customer communication. Instead of sending only generic campaigns, brands can trigger emails based on real customer actions inside Nector.

Why Loyalty Events Matter for Email Automation

Most ecommerce brands already send email campaigns. But not every brand connects those emails to loyalty behavior. That creates a gap. Customers may earn rewards, but they do not receive a timely reminder. They may create a coupon, but they may not get a follow-up email encouraging them to use it. They may be close to coin expiry, but they may not know they need to act.

Loyalty data becomes more useful when it powers communication.

Nector's integrations page positions Mailchimp as an email and WhatsApp marketing integration that helps brands use customer loyalty data for segmentation, automated emails, birthdays, anniversaries, and reward milestones.

That is the main value of the Nector + Mailchimp integration: it helps merchants turn loyalty events into customer journeys.

For example:

What the Nector + Mailchimp Integration Does

The Nector + Mailchimp integration connects Nector customer events with Mailchimp automations.

At a product level, the integration helps merchants:

• Connect Mailchimp with Nector using a private API key and Audience ID.
• Send selected Nector events into Mailchimp.
• Use Nector events as triggers inside Mailchimp customer journeys.
• Trigger emails when customers earn wallet coins.
• Trigger emails when customers create coupons using wallet coins.
• Support other event-based workflows such as referrals, coin expiry notifications, and review requests, depending on setup.
• Reduce manual campaign work for loyalty and retention teams.

Nector highlights two commonly used events: Wallet Coins Rewarded, which is sent when wallet coins are rewarded in Nector, and Coupon Is Created, which is sent when a customer uses wallet coins to create a discount or coupon code in Nector.

This is not just a basic email integration. It is a retention workflow integration. Nector handles the loyalty action. Mailchimp handles the automated email journey.

How the Nector + Mailchimp Integration Workflow Works

Step 1: Open Email & WhatsApp Marketing in Nector

The setup starts inside the Nector dashboard.

Merchants go to the Integrations page, select Email & WhatsApp Marketing from the sidebar, and find Mailchimp in that section. From there, they click Configure to open the Mailchimp integration page.

This is where Nector starts connecting loyalty activity with Mailchimp automations.

Step 2: Get the Mailchimp Private API Key

To enable the integration, the merchant needs a private API key from Mailchimp.

Nector's setup guide explains that merchants should log in to Mailchimp, click their account name, open the profile section, go to Extras → API keys, create a new API key, and copy it into the Nector dashboard. The server prefix is filled automatically.

This API key allows Nector to send selected events into the connected Mailchimp account.

Step 3: Add the Mailchimp Audience ID

Next, the merchant needs to find the Mailchimp Audience ID and paste it into the Nector dashboard.

The Audience ID tells Nector which Mailchimp audience should receive the event data. After the API key and Audience ID are added, the merchant clicks Initialize to enable the integration.

This step connects the two platforms.

Step 4: Create Events in Nector

Once the integration is enabled, the merchant can move to the Events tab inside Nector and create an event that should be sent to Mailchimp.

Nector explains that the merchant selects the event they want to notify the external integration about. For example, they can choose Wallet Coins Rewarded and send that event to Mailchimp.

This is where the merchant decides which loyalty actions should become email triggers.

Step 5: Send a Test Event

Before the event can be used inside Mailchimp, the merchant needs to send a test event from Nector.

Nector notes that sending a test event makes the event available inside the Mailchimp dashboard so it can be used as a trigger. It also notes that the email ID used for the test must exist in the store's customer database.

This step is important because it confirms that Mailchimp can receive the Nector event correctly.

Step 6: Build a Mailchimp Customer Journey

After the event is available in Mailchimp, the merchant can create a customer journey.

Inside Mailchimp, the merchant goes to Automations → Overview, clicks Build From Scratch, names the journey, chooses a starting point, goes to API & Integrations, and selects Event API. In Nector's wallet reward example, the merchant chooses the wallet reward create trigger.

Mailchimp's own documentation also explains that custom events can be used for behavioral targeting and that paid marketing plans have access to Event API triggers for automation flows.

Step 7: Add the Email Action

Once the Nector event is selected as the starting point, the merchant adds a journey point and chooses Send Mail.

From there, the merchant configures the subject line, email content, and journey settings. When the customer performs the selected action in Nector, Mailchimp can trigger the email journey.

This turns loyalty activity into automated customer communication.

Use Cases for Shopify and DTC Brands

1. Wallet Coins Rewarded Email

When a customer earns wallet coins in Nector, Mailchimp can trigger an email telling them what they earned.

Example message: “You just earned 100 coins. Use them on your next order.”

This keeps loyalty value visible after a purchase, review, referral, or campaign.

2. Coupon Created Email

Nector's help guide lists Coupon Is Created as a commonly used event. This event is sent when a customer uses wallet coins to create a discount or coupon code in Nector.

A brand can use this event to trigger an email that reminds the customer to use the coupon before they forget.

Example message: “Your reward coupon is ready. Apply it to your next order.”

3. Referral Follow-Up Emails

Events can also be sent for actions such as when a new customer is referred. Nector mentions referral-related events as another possible use case for Mailchimp journeys.

This can help brands notify referrers, remind them about earned rewards, or encourage another referral.

4. Coin Expiry Notifications

Coin expiry reminders are useful because customers often forget their loyalty balance.

Nector's help guide says events can be sent for coin expiry notifications. A brand can use Mailchimp to send a reminder before coins expire.

Example message: “Your coins are expiring soon. Redeem them before they expire.”

This gives customers a practical reason to return.

5. Review Request Journeys

Nector also mentions review request events as a possible event use case.

For DTC brands, review requests are a strong post-purchase touchpoint. When connected with loyalty, brands can ask for feedback and remind customers about reward opportunities in the same customer journey.

6. Post-Purchase Loyalty Education

Not every customer understands how a loyalty program works after one purchase.

Brands can use Mailchimp journeys to educate customers after key Nector events:

• How many coins did they earn
• How to redeem coins
• What rewards are available
• How referrals work
• How reviews can earn rewards
• What happens when coins expire

This helps turn first-time buyers into active loyalty members.

7. Loyalty-Based Segmentation

Nector's integration page describes Mailchimp as a way to use customer loyalty data for segmentation based on customer preferences, purchase history, and behavior.

This can help brands create more relevant campaigns for different customer groups, such as customers who earned coins, created coupons, referred friends, or are close to expiry.

Final Thoughts

The Nector + Mailchimp integration is valuable because it connects customer loyalty activity with email automation.

Nector helps brands manage loyalty, wallet coins, coupons, referrals, reviews, and reward workflows. Mailchimp helps brands send automated customer journeys. When these systems work together, a customer action in Nector can become a timely email in Mailchimp.

That matters because customers do not always remember their coins, coupons, rewards, referrals, or expiry dates on their own. They need clear reminders at the right time.

For Shopify, DTC, ecommerce, and omnichannel brands, this integration helps turn loyalty data into customer communication that feels timely, useful, and connected.
