How to connect WooCommerce to MailerLite

The MailerLite plugin for WooCommerce allows you to automatically sync your WooCommerce customers with your MailerLite subscribers. By installing the plugin, you will be able to select a group in MailerLite to which your WooCommerce customers will be added. Furthermore, you will have access to additional e-commerce features such as abandoned cart emails, campaign purchase tracking and much more.

To install the MailerLite plugin for WooCommerce:

  1. Use the right-hand dropdown menu to navigate to the Integrations page.

  1. Find WooCommerce and click Use.

  1. Scroll to the E-Commerce integration section and click the ON button.

  1. Find Your account API key and click Copy (you will need it later).

  1. Go to your WordPress dashboard.

  2. In the sidebar, click Plugins followed by Add new.

  1. Use the search field to search for “MailerLite”.

  2. Find the WooCommerce - MailerLite plugin and click Install followed by Activate.

  1. In the sidebar, click WooCommerce followed by Settings.

  1.  Click the Integrations tab.

  2. In the MailerLite API key field, paste Your account API key (the one you copied earlier) and click Validate key.

  1. Then select the group where your subscribers will be added during the checkout process.

  2. Add your Consumer key.

  3. Add your Consumer secret.

Note: To get the Consumer key and Consumer secret, go to WooCommerce > Settings > Advanced. We recommend that you open this page in a new browser tab. Choose REST API and click the Add Key button.

In the Description field, enter MailerLite or another value of your choice. Select your User and choose Read permissions.

Click Generate API key. You will redirect to the Consumer Key and Consumer Secret window. Copy them to your MailerLite integration.

Your Consumer key and Consumer secret are an integral step in installing the WooCommerce - MailerLite integration. It’s important that you do not skip this step.

  1. Click Save changes.

That’s it! Your WooCommerce account is now connected to your MailerLite account.

When you install the WooCommerce-MailerLite plugin, your existing subscribers in MailerLite will have their purchase data synced.

Additionally, all new subscribers that agree to join your mailing list will automatically be added to MailerLite.

Customers that already existed in your WooCommerce list but did not already exist in your MailerLite list will not be synced, along with new subscribers that sign up without accepting marketing emails.

There are four key features in the WooCommerce - MailerLite integration that enhance your e-commerce email marketing and track its success.

1. Data synchronization and sales tracking

When you install the WooCommerce - MailerLite integration, new subscribers that accept marketing will automatically have their name and email address added to your MailerLite subscriber list. There are also custom WooCommerce fields that are added to your list of subscriber fields to help you track sales. 

WooCommerce fields include:

  • Woo orders count - The number of orders that the subscriber has made

  • Woo total spent - The total amount of money that subscriber has spent on your WooCommerce store

  • Woo last order - The date of the last order that subscriber made on your WooCommerce store

In addition to using these fields to collect data, you can also use them to search for subscribers and create segments.

Note:  You may find that the Total revenue data in your campaign report does not match the number in your subscriber’s Woo total spent field. This is because Total revenue only refers to the revenue generated from that MailerLite campaign. Your Woo total spent field includes all purchases, including those not made through MailerLite.


2. Product blocks in your newsletters

Save time drafting your newsletters by using our e-commerce product blocks. Product blocks automatically import images, descriptions, and prices of your products and link directly to your WooCommerce store.

To add a product block to your newsletters:

  1. Open your campaign in the Drag & drop editor.

  2. In the left-hand sidebar, use the dropdown menu to select E-commerce integration blocks.

  1. Drag and drop your preferred product block into your newsletter.

  1. Click the product block to select it.

  2. In the right-hand sidebar, click Add products from your store.

  1. A window will appear in which you can select the products you wish to display.

  2. Click Insert once you have selected your product.

  3. If you wish to edit the information displayed in your product block, click the product block to select it. Then, in the sidebar, click the pencil icon next to your product.

Here, you can edit the image, product name, URL, price, and CTA button. 

3. E-Commerce automation triggers

When you install the WooCommerce - MailerLite integration, you will find additional e-commerce triggers available in your workflow editor.

These triggers include: 

  • Abandoned cart

  • Purchases any product

  • Purchases specific product

  • Purchases from category

Note: In order for a purchase to trigger a workflow, the order status must be Completed and the purchase must be paid.

4. Abandoned cart emails

By creating an automation with the trigger Abandoned cart, you can create responsive emails that send automatically after a subscriber has abandoned their cart.

Abandoned cart emails can be triggered in various ways in your WooCommerce store:

  • Registered and logged in customer - When a customer logs in to your store and adds a product to the cart, they can be triggered immediately if their email address is already on your MailerLite subscriber list.

  • Existing subscriber - If a customer on your subscriber list fulfills an order form and enters their email address, they can be triggered immediately without continuing to the next step.

  • First-time buyer - A first-time buyer can be triggered after they provide contact information during the checkout process, or if the buyer subscribes to your email marketing by ticking the checkbox. In this case, the entered email address is added immediately to your MailerLite subscriber list and they are eligible immediately to trigger abandoned cart automation emails. If a first-time customer fails to enter their email address before they abandon the checkout, nor are they on your subscriber list, then they will be unable to trigger an abandoned cart automation

Note: Unsubscribed subscribers can’t trigger abandoned cart automations. You can only send abandoned cart emails to shoppers who are on your MailerLite subscriber list.


For everything you need to know about abandoned cart emails, including step-by-step setup instructions, take a look at our article How to create an abandoned cart automation.

If a customer of your WooCommerce store makes a purchase, and is not added to your active subscriber list or does not trigger a purchased-based automation, you can check the following factors:

  • Order status - In order to be successfully added to your active subscriber list or trigger any purchased-based automations, the customer’s order status must be Complete. If your customer's order status is still Payment pending or Processing, they will not trigger any actions in MailerLite.

  • Accepts marketing - If your customer did not check the box to accept email marketing at checkout, they cannot be synced to your MailerLite account.

Additionally, on your order page in the bottom right corner, you will find a window labeled MailerLite. The information in this window is there to assist you in making sure your customers are synced successfully. There are six factors in the MailerLite window that you can review:

  • Signed up for mailing list - Indicates whether or not a subscriber has accepted marketing or signed up for your mailing list

  • Subscribed to mailing list - This factor then indicates whether or not the subscriber has been successfully added. For example, if you have double opt-in for API enabled subscribers won’t be subscribed to the mailing list until they confirm their subscription in their inbox

  • Already in the subscriber list - Indicates that the subscriber was previously subscribed to your mailing list prior to making this purchase

  • Subscriber data updated - Indicates that the existing subscriber has been updated with new information included in this order

  • Order data submitted - This will show whether or not the subscriber's order information was added to MailerLite

  • Order tracking completed - Simply indicated that the customer, along with their order data, have been successfully added to MailerLite and the sync is complete
