WooCommerce Post-Purchase Emails

January 03, 2026 1 min read Tutorial

Why Post-Purchase Automation Matters

The moments after a purchase are the highest-engagement window you have. A well-timed review request or cross-sell email can significantly increase LTV without additional ad spend.

Triggering on Order Completion

Use the woocommerce_order_status_completed hook to fire an API call to AcelleMail:

add_action('woocommerce_order_status_completed', function($order_id) {
    $order = wc_get_order($order_id);
    $email = $order->get_billing_email();
    $first_name = $order->get_billing_first_name();

    // Add to post-purchase automation list
    wp_remote_post('https://mail.yourdomain.com/api/v1/subscribers', [
        'headers' => ['Authorization' => 'Bearer TOKEN', 'Content-Type' => 'application/json'],
        'body' => json_encode([
            'email'      => $email,
            'first_name' => $first_name,
            'list_uid'   => 'POST_PURCHASE_LIST_UID',
        ]),
    ]);
});

Post-Purchase Sequence

Set up an AcelleMail automation with this timing:

Email Delay Goal
Order thank you Immediately Confirm + set expectations
Usage tips Day 3 Reduce returns, build loyalty
Review request Day 7 Social proof
Related products Day 14 Upsell / cross-sell

Product-Specific Tags

Pass order product categories as subscriber tags to personalise follow-ups:

$categories = [];
foreach ($order->get_items() as $item) {
    $terms = get_the_terms($item->get_product_id(), 'product_cat');
    foreach ($terms as $term) $categories[] = $term->slug;
}
// Include 'tags' => $categories in the API payload
