Add specific tag to the subscribed Woo shop customers

Hi @webreneszansz Yes!

You will use our mailchimp_get_ecommerce_merge_tags filter

add_filter('mailchimp_get_ecommerce_merge_tags', 'mailchimp_ecommerce_add_product_tags', 10, 2);
function mailchimp_ecommerce_add_product_tags($merge_fields, $order) {
	$woo_order = wc_get_order($order->getId());

    // Initialize tags array
    $tags_to_add = array();
    
    // Loop through order items
    foreach ($woo_order->get_items() as $item_id => $item) {
        $product_id = $item->get_product_id();
        
        // Map product IDs to tags
        // Replace these product IDs with your actual product IDs
        $product_tag_mapping = array(
            133 => 'ws01',  // Replace 123 with Workshop 01 product ID
            130 => 'ws02',  // Replace 456 with Workshop 02 product ID
            178 => 'ws03',  // Add more mappings as needed
        );
        
        // Check if this product should add a tag
        if (isset($product_tag_mapping[$product_id])) {
            $tags_to_add[] = $product_tag_mapping[$product_id];
        }
    }
    
    // If we have tags to add, update the merge fields
    if (!empty($tags_to_add)) {
        // Add the tags as a merge field
        // You might want to use TAGS or a custom merge field
        $merge_fields['TAGS'] = implode(',', array_unique($tags_to_add));
    }
	    
    return $merge_fields;
}

And alternative for SKU usage

add_filter('mailchimp_get_ecommerce_merge_tags', 'mailchimp_ecommerce_add_product_tags_by_sku', 10, 2);
function mailchimp_ecommerce_add_product_tags_by_sku($merge_fields, $order) {
    
	$woo_order = wc_get_order($order->getId());

    // Initialize tags array
    $tags_to_add = array();
    
    // Loop through order items
	foreach ($order->get_items() as $item_id => $item) {
        $product = $item->get_product();
        $sku = $product->get_sku();
        
        // Map SKUs to tags
        $sku_tag_mapping = array(
            'WORKSHOP-01' => 'ws01',
            'WORKSHOP-02' => 'ws02',
            // Add more mappings
        );
        
        if (isset($sku_tag_mapping[$sku])) {
            $tags_to_add[] = $sku_tag_mapping[$sku];
        }
    }
    
    // If we have tags to add, update the merge fields
    if (!empty($tags_to_add)) {
        // Add the tags as a merge field
        // You might want to use TAGS or a custom merge field
        $merge_fields['TAGS'] = implode(',', array_unique($tags_to_add));
    }
	    
    return $merge_fields;
}

Setup Instructions

The code should be added to one of these locations:

• Preferred: A custom plugin (create a simple one for this functionality)
• Alternative: Your theme’s functions.php file (in child theme if using one)
• Also good: A site-specific plugin or code snippets plugin

1. In Mailchimp:
   • Ensure you have a TAGS merge field (or create a custom one)
   • Set up automation rules based on these tags if needed
2. In WordPress:
   • Find your product IDs (hover over products in WooCommerce admin to see ID in URL)
   • Update the $product_tag_mapping array with actual product IDs
   • Add the code to your site
3. Testing:
   • Place a test order
   • Check if the customer appears in Mailchimp with the correct tags
   • Verify in Mailchimp’s activity feed

Important Notes

• Tags are added when the order is placed (not just completed)
• Multiple products in one order will add multiple tags
• The code uses the mailchimp_get_ecommerce_merge_tags hook from the MC WooCommerce plugin
• Make sure the Mailchimp for WooCommerce plugin is active and properly configured

This should give them everything they need to implement product-based tagging!

Hi @webreneszansz

How the plugin works by default? Will we see the bought product in Mailchimp at the subscribers? Can we create segments based on the purchased conrete products?

Answer: yes – here is more info from MC Support site: Getting Started with Tags: https://eepurl.com/dBYjo9 Manage Tags: https://eepurl.com/dBYjpv

The Mailchimp for WooCommerce integration automatically syncs customer and order data, making this information available for merge tags.

You would want to make sure you have properly mapped your merge tags to ensure the data passes over. Here is info on merge tags and how to set that up

If you need to store and use data not automatically synced by the WooCommerce integration (e.g., a customer’s favorite product category), you can create custom fields in your Mailchimp audience and then associate custom merge tags with them.

• Go to Audience > Settings > Audience fields and merge tags in Mailchimp to manage custom fields.

Is it possible with this plugin? I only would like to find the easiest solution, because in this case, we don’t need the additional tagging

Answer: yes – I have sent you information on the simplest way. Have you tried that out? Here are some additional resources:MC Quick Start videos or Complete Video Series in case you are a visual learner.
