What is a transactional email?

A transactional email is an email that is sent in response to an action that a customer has taken. They are typically triggered by an event, such as signing up for a newsletter, making a purchase, or requesting a password reset. Transactional emails usually contain information that is time-sensitive and relevant to the customer’s recent activity.

These emails are different from marketing or promotional emails, which are typically sent to a large group of people in an attempt to generate interest in a product or service. Transactional emails are sent to an individual customer in response to a specific action that they have taken.

Why transactional emails matter

Transactional emails are important because they provide a way for businesses to communicate directly with their customers. They can be used to provide information about a purchase, update a customer on the status of an order, or even provide customer support.

Transactional emails can also be used to build relationships with customers and create loyalty. By providing valuable information and offering customer support, businesses can create a bond with their customers that can lead to repeat business.

In fact, a study by Experian found that transactional emails have an open rate of nearly 76%, which is significantly higher than the average open rate for marketing emails. Additionally, transactional emails have a click-through rate of nearly 16%, which is also higher than the average click-through rate for marketing emails.

This shows that transactional emails are not only opened more often, but they are also more likely to result in a desired action from the recipient. For businesses, this means that transactional emails can be a powerful tool for driving sales and loyalty.

Types of transactional emails

There are several transactional emails that you can send to your customers. They include:

1. Welcome emails

Welcome emails are sent to new customers. They are a great way to introduce your business and build a relationship with your customers.

Welcome emails should be personal and friendly. They should also include a call to action (CTA) that encourages the customer to take action. Also, make sure to include your company’s logo and contact information.

They help you build a relationship with your customer and give you a chance to upsell or cross-sell your products or services.

2. Order confirmation emails

Order confirmation emails are sent to customers after they place an order. They confirm the details of the order and provide the customer with tracking information. They should also include a CTA that encourages the customer to track their order.

These are another type of transactional emails that can’t be ignored. If a customer receives a confirmation email after ordering a product, they’re more likely to be satisfied with the purchase.

3. Shipping confirmation emails

Shipping confirmation emails are sent to customers after their order has shipped. They provide the customer with tracking information and let them know when to expect their order.

However, shipping confirmation emails should be clear and concise. They should also include a CTA that encourages the customer to track their order.

The role of shipping confirmation emails is to provide customers with information about their recently shipped order. This includes the tracking number and expected delivery date. 

4. Payment confirmation emails

Payment confirmation emails are sent to customers after they make a payment. They confirm the details of the payment and provide the customer with a receipt.

These emails serve as a receipt for customers, providing them with confirmation that their payment has been processed. They also help to build trust with customers by providing transparency into the payment process.

Also, these emails can help reduce customer support inquiries related to payments, as customers can refer to the email for confirmations instead of contacting customer support.

5. Account creation confirmation emails

Account creation confirmation emails are sent to customers after they create an account. They confirm the details of the account and provide the customer with login information.  These emails also aim to build trust with the customer and encourage them to start using the account.

Account creation confirmation emails should be clear and concise. They should include the customer’s username, password, and any other important information. The email should also include a link to the company’s website and contact information in case the customer has any questions.

6. Password reset emails

Password reset emails are sent to customers who have forgotten their password. They provide the customer with a link to reset their password.

A password reset email plays an important role in the customer journey. It allows customers who have forgotten their password to reset it and regain access to their account.

When writing a password reset email, be sure to include a link to the password reset page. Also, be sure to include instructions on how to reset their password.

Mistakes to avoid with transactional emails

1. Not sending transactional emails

Transactional emails are automatically triggered by customer actions and are an essential part of the customer journey. By not sending these emails, you are missing out on valuable opportunities to engage customers. If a customer abandons their cart, for example, you should send a reminder email. If a customer makes a purchase, you should send a receipt.

2. Sending transactional emails from a marketing email

Transactional emails should always come from a transactional email address (e.g. [email protected]). This helps customers trust that the email is legitimate and not a marketing email.

3.Not personalizing transactional emails

Transactional emails are a great opportunity to personalize your messages and build a relationship with your customers. Include the customer’s name in the email and use language that feels friendly and human.

4. Not optimizing transactional emails for mobile

Transactional emails are often opened on mobile devices, so it’s important to optimize your email template for mobile. Use a responsive email template and keep your message brief and to the point.

5. Not A/B testing transactional emails

Transactional emails are a great opportunity to test different subject lines, call to actions, and email content. A/B testing can help you improve your email open and click-through rates, so be sure to test different elements of your transactional emails.

Transactional emails best practices

When it comes to transactional emails, the overarching best practice is to make sure these types of messages are well-designed and offer a positive user experience. In addition, it’s important to keep the following in mind:

Keep it simple

Transactional emails should be straightforward and to the point. They should also be free of any unnecessary design elements or copy that could clutter the message and make it difficult for recipients to digest the information.

To ensure simplicity , start by clearly defining the purpose of the email. Once you know what needs to be communicated, determine the best way to do so in as few words as possible. This may require some trial and error, but it will be worth it in the end.

Make it mobile-friendly

Since the majority of transactional emails are now opened on mobile devices, it’s important to make sure your messages are optimized for small screens. This includes using a responsive email template, keeping the design simple, and using large, easy-to-tap buttons for any CTAs.

By making your transactional emails mobile-friendly, you’ll be able to improve the recipient’s experience and increase the likelihood that they’ll take the desired action.

Use a strong call-to-action

Transactional emails should always include a strong call-to-action (CTA) that encourages recipients to take the desired action. The CTA should be clear, concise, and easy to spot so that recipients can quickly and easily take the desired action. It could be something as simple as “click here to view your order” or “click here to change your password.”

Whatever you choose, make sure it’s relevant to the email’s purpose and that it stands out from the rest of the message. Including a CTA will not only help you achieve your goals, but it will also give recipients a sense of what they need to do next.

Personalize where possible

One of the best ways to improve the effectiveness of your transactional emails is to personalize them. This can be done by including the recipient’s name in the subject line or body of the email, or by using dynamic content to customize the message based on the recipient’s preferences or past interactions.

Personalization can go a long way in making a transactional email more effective. By including the recipient’s name or other personal information in the email, you can make the message feel more relevant and engaging.

Proofread your email

Since transactional emails are generally triggered by an action that a recipient has taken, they often contain sensitive information. For this reason, it’s important to proofread your email before sending it to ensure that all of the information is accurate and free of any typos or grammatical errors.

In addition to proofreading the email itself, you should also test the email to make sure it renders properly on various devices and email clients. This will help you avoid any potential delivery issues and ensure that recipients can easily view and interact with your message.

Monitor your results

Finally, it’s important to monitor the results of your transactional emails to see how they’re performing. This can be done by tracking things like open rate, click-through rate, and unsubscribe rate.

Monitoring your results will not only help you improve the effectiveness of your transactional emails, but it will also give you insights into the overall health of your email list. By paying attention to your results, you’ll be able to make the necessary adjustments to keep your list clean and your emails performing at their best.

Test, test, test

As with any email marketing campaign, it’s important to test your transactional emails before you send them to your entire list. This will allow you to identify any potential issues and make sure that the email looks and functions as intended.


When it comes to transactional emails , there are a number of ways to get the most out of your text and design. You can be as creative as you like, or you can use a simple HTML template, but in the end, the important thing is to be clear and concise.

The above best practices for transactional emails are simple to follow and can help you improve your transactional emails. The best part is that you can use email marketing agencies like Labnify to handle these best practices and improve your email marketing campaigns.
