In the world of e-commerce, the customer journey doesn't end with a purchase. In fact, that's just the beginning. Post-purchase emails are a critical component of building customer loyalty and driving repeat business. These emails allow you to continue the conversation with your customers, provide valuable information, and encourage them to engage with your brand again in the future. By crafting effective post-purchase email campaigns, you can turn one-time buyers into lifelong brand advocates.

Platforms like Klaviyo, and Yotpo make it easier than ever to create and automate compelling post-purchase email flows. In this comprehensive guide, we'll dive into the best practices for post-purchase email automation, with plenty of real-world post-purchase email examples to inspire your own campaigns. 

What are post-purchase emails?

Post-purchase emails are a series of emails sent to customers after they've made a purchase from your online store. These emails are designed to nurture the customer relationship, provide important information about the order, and encourage future engagement with your brand.

Post-purchase emails play a critical role in the e-commerce lifecycle. They bridge the gap between the initial purchase and future interactions, helping to build trust, loyalty, and repeat business. A well-crafted post-purchase email flow can transform a one-time buyer into a lifelong customer.

How to write a post-purchase email

Writing effective post-purchase emails requires a strategic approach. Here are some best practices to keep in mind:

  1. Personalize the content: Use the customer's name and reference their specific purchase to make the email feel tailored to them.
  2. Keep it concise: Customers are busy, so keep your emails short, sweet, and to the point.
  3. Provide value: Every post-purchase email should offer something of value to the customer, whether it's important information about their order, helpful tips for using the product, or exclusive offers.
  4. Use a clear call-to-action: Encourage customers to take a specific action, like leaving a review or making another purchase, with a prominent CTA button.
  5. Optimize for mobile: More than half of all emails are opened on mobile devices, so make sure your post-purchase emails are optimized for small screens.
  6. Test and iterate: Continuously monitor your post-purchase email performance and make data-driven improvements over time.
  7. Automate where possible: Use post-purchase email automation tools like Klaviyo to streamline your campaigns and ensure timely delivery.

By following these best practices, you can craft post-purchase email campaigns that delight customers and drive results for your business.

Why are post-purchase emails important?

Post-purchase emails are a vital component of any successful e-commerce strategy. Here's why:

Builds trust

Sending timely, relevant post-purchase emails shows customers that you care about their experience and are committed to providing excellent service. This helps build trust in your brand. For example, a follow up email after purchase order that provides an order confirmation and shipping details reassures the customer that their order is being handled promptly and professionally.

Strengthens customer relationships

Post-purchase emails allow you to continue the conversation with customers even after they've completed a purchase. By providing valuable content, personalized recommendations, and exclusive offers, you can deepen the customer relationship and encourage long-term loyalty. A thoughtful welcome email after purchase, for instance, can make a customer feel appreciated and excited to engage with your brand again.

Increases customer lifetime value

Customers who feel valued and engaged are more likely to make repeat purchases and spend more over time. Post-purchase email campaigns that cross-sell related products, offer loyalty rewards, or provide helpful tips can significantly boost customer lifetime value.

Promotes positive reviews and feedback

Satisfied customers are often happy to share their positive experiences, but they may need a little nudge. A well-timed follow up with a customer after purchase email asking for a review or feedback can generate valuable social proof and user-generated content for your brand. Plus, actively seeking out customer feedback shows that you value their opinion and are committed to continuous improvement.

Post-purchase email benchmarks

To gauge the success of your post-purchase email campaigns, it's important to benchmark your performance against industry standards. Here are some key metrics to track:

  • Open rate: The average open rate for post-purchase emails is 40.5%. This is significantly higher than the average open rate for promotional emails, which hovers around 21%.
  • Click-through rate (CTR): Post-purchase emails also tend to have higher click-through rates than promotional emails. The average CTR for post-purchase emails is 16.7%, compared to 2.62% for promotional campaigns.
  • Conversion rate: The ultimate goal of any email campaign is to drive conversions. For post-purchase emails, the average conversion rate is 1.09%. This may seem low, but it's important to remember that these emails are primarily focused on building relationships and encouraging future purchases, rather than driving immediate sales.
  • Unsubscribe rate: While you want customers to engage with your post-purchase emails, it's also important to monitor unsubscribe rates. The average unsubscribe rate for post-purchase emails is 0.5%-1%. If your unsubscribe rate is significantly higher than this, it may be a sign that your emails are not providing value or are too frequent.

Keep in mind that these benchmarks can vary depending on your industry, audience, and specific campaign goals. Use them as a starting point, but continually monitor and optimize your own post-purchase email flow based on your unique data and insights.

Benefits of sending a post-purchase email in e-commerce

Post-purchase emails offer a wide range of benefits for ecommerce businesses. Let's explore some of the most significant advantages:

Enhanced customer experience

Sending timely, relevant, and personalized post-purchase emails shows customers that you value their business and care about their experience. By providing important information, helpful resources, and exclusive offers, you can enhance the overall customer experience and build long-term loyalty.

For example, a post-purchase email flow that includes an order confirmation, shipping updates, and a thank you note with a special offer for the next purchase demonstrates a commitment to customer satisfaction at every stage of their journey.

Encourages repeat purchases

Post-purchase emails are a powerful tool for encouraging repeat purchases. By staying top-of-mind and providing compelling reasons to shop again, you can turn one-time buyers into repeat customers.

Consider a post-purchase email campaign that includes personalized product recommendations based on the customer's previous purchase, a loyalty program update with the number of points needed to earn a reward, and a limited-time discount code. These tactics work together to encourage the customer to return to your store and make another purchase.

Increases average order value

In addition to encouraging repeat purchases, post-purchase emails can also help increase the average order value (AOV). By cross-selling complementary products, upselling higher-value items, and offering bundle deals or free shipping thresholds, you can motivate customers to add more items to their cart and spend more per order.

For instance, if a customer buys a pair of running shoes, a post-purchase email could recommend matching athletic socks, insoles, or a hydration pack. By showcasing the value and convenience of these related products, you can increase the likelihood of a larger order.

Enhances brand recall

In a crowded e-commerce marketplace, it's essential to keep your brand top-of-mind. Post-purchase emails help enhance brand recall by regularly engaging with customers and reinforcing your brand identity.

A consistent post-purchase email flow that features your brand's logo, colors, voice, and values in every message helps customers remember and recognize your brand. Over time, this repeated exposure can lead to increased brand loyalty and advocacy.

Strengthens trust

Trust is the foundation of any strong customer relationship. Post-purchase emails help strengthen trust by demonstrating transparency, reliability, and a commitment to customer satisfaction.

For example, a post-purchase email that proactively addresses common questions or concerns about a product, offers easy return or exchange options, and provides helpful usage tips shows that you stand behind your products and prioritize the customer's needs. This level of service and support helps build trust and confidence in your brand.

Essential tips for post-purchase email success

To maximize the impact of your post-purchase emails, keep these essential tips in mind:

Ensure timely delivery

Timing is everything when it comes to post-purchase emails. Make sure to send order confirmations immediately after purchase, shipping confirmations as soon as the order is on its way, and delivery confirmations within 24 hours of the package arriving.

Automated post-purchase email flows can help ensure that messages are delivered at the right time, every time. Klaviyo, for example, offers pre-built flows for order confirmations, shipping updates, and delivery notifications that can be customized to fit your brand.

Personalize the email content

Personalization is key to creating post-purchase emails that resonate with customers. Use the data you've collected about each customer, such as their name, purchase history, and browsing behavior, to tailor the content and offers to their individual needs and preferences.

For example, a post-purchase email that recommends products based on the customer's previous purchases and includes their name in the subject line is more likely to capture their attention and encourage engagement.

Craft attention-grabbing subject lines

The subject line is often the first thing a customer sees when they receive a post-purchase email, so it's important to make it count. Craft subject lines that are clear, concise, and compelling, while also setting accurate expectations about the content of the email.

Some effective tactics for post-purchase email subject lines include:

  • Using the customer's name
  • Mentioning the specific product or order number
  • Creating a sense of urgency or excitement
  • Asking a question or promising a benefit

For example, "Get the most out of your new [Product Name], [Name]!" or "Your order #[Number] is on its way - track it here!"

Use compelling and clear visuals

Visuals can make a big impact in post-purchase emails. Use high-quality product images, infographics, or even videos to showcase your products, provide instructions or tips, and break up large blocks of text.

Make sure to use alt text for all images and keep the overall design clean, clear, and mobile-friendly. Avoid overloading the email with too many images or complex layouts that may not render correctly on all devices.

Finally, it's important to continuously monitor and optimize your post-purchase email performance. Keep a close eye on key metrics like open rates, click-through rates, conversion rates, and unsubscribe rates to identify areas for improvement.

A/B test different subject lines, content, offers, and designs to see what resonates best with your audience. Use tools like Google Analytics and Klaviyo's reporting dashboard to track the impact of your post-purchase emails on revenue, repeat purchases, and customer lifetime value.

Remember, post-purchase email optimization is an ongoing process. What works well today may not work as well tomorrow, so it's important to stay agile and adapt your strategies based on data and customer feedback.

How to automate post-purchase emails

Manually sending post-purchase emails can be time-consuming and inefficient, especially as your business grows. That's where automation comes in. By setting up post-purchase email automation flows, you can ensure that the right messages are sent to the right customers at the right time, without having to lift a finger.

Most email marketing platforms, including Klaviyo, offer pre-built templates and workflows for common post-purchase email sequences. For example, the Klaviyo post purchase flow offers order confirmations, shipping updates, and product reviews. These templates can be easily customized with your brand's logo, colors, and messaging, and triggered based on specific customer actions or timelines.

For example, you might set up a post-purchase email flow in Klaviyo that includes:

  1. An order confirmation email sent immediately after purchase
  2. A shipping confirmation email sent when the order status changes to "shipped"
  3. A delivery confirmation email sent 24 hours after the estimated delivery date
  4. A product review request email sent 7 days after delivery
  5. A replenishment reminder email sent 30 days after delivery (for consumable products)
  6. A cross-sell/upsell email sent 60 days after delivery featuring complementary products

By automating these messages, you can provide a seamless post-purchase experience for your customers while freeing up time to focus on other aspects of your business.

Frequently asked questions

When to send a post-purchase email: What’s the best time?

The timing of your post-purchase emails will depend on the specific message and goal. Generally, order confirmations should be sent immediately, shipping confirmations within 24 hours of the order being shipped, and delivery confirmations within 24 hours of delivery.

Other post-purchase emails, such as product reviews, replenishment reminders, or cross-sell/upsell offers, can be sent a few days to a few weeks after delivery, depending on the typical customer buying cycle for your products.

What is a post-purchase email flow?

A post-purchase email flow is a series of automated emails that are triggered based on a customer's purchase and sent over a period of time. These emails are designed to keep the customer engaged, informed, and primed for future purchases. A typical post-purchase email flow might include an order confirmation, shipping update, delivery confirmation, product review request, and replenishment reminder.

What is the open rate for post-purchase emails?

According to recent industry benchmarks, the average open rate for post-purchase emails is around 40-45%, which is significantly higher than the average open rate for promotional emails (10-15%).
