If you want to understand in depth what they are and why they are important, we recommend you to read the article "What are transactional messages and why are they important?".
Although these messages are usually simple, they have a high impact. Their open rate is much higher than that of other marketing emails: it ranges between a 30% and one 40%while other promotional emails range between a 15% and one 25%.
Taking advantage of the high attention that these messages generate, it is key to surprise customers with relevant and personalized content.
What makes transactional messages special
Transactional messages are triggered automatically when a user performs a specific action, such as registering, making a purchase, visiting a page, downloading content or completing a subscription. They are personalized in nature, as they respond directly to user interactions.
However, in addition to being informative, they can also be approachable and friendly. Think about this: when was the last time you felt valued when you received a confirmation or welcome email? Don't miss the opportunity to create a memorable experience for your customers.
Key tips to optimize your transactional messages
1. Customize the content
Include the recipient's name in the body of the email. This creates a sense of closeness and increases the likelihood of interaction. If it is an eCommerce message, use the order data to further personalize the content. For B2B messages, make sure registration forms capture the full name and it is included in the email automatically.
Also, use a real sender and a trustworthy email address, rather than a generic address such as marketing@empresaabc.com. People interact more with messages that appear to be sent by someone specific than those that appear to be bulk.
2. Guide the customer's next steps with personalized suggestions.
The eCommerce giants, such as Amazon, have perfected the technique of suggesting additional products based on previous purchases. You can apply this strategy in your transactional messaging. In B2B, this can translate into content recommendations, such as your blog articles or feature briefs, and invitations to webinars or personalized consultations.
To optimize these strategies, it is essential to A/B testing and adjust the contents according to the results.
3. Facilitates direct communication
Avoid sending messages from mailboxes no-reply. This creates a barrier between you and the customer, discouraging any kind of interaction. In the case of non-responsive eCommerce emails, be sure to include easily visible contact buttons, such as links to FAQs, customer service areas or order inquiries.
4. Provide the information your users are looking for
Take advantage of navigation data to anticipate your customers' needs. For example, include direct links in the footer of your messages to relevant pages, such as the most visited product sections or frequently asked questions.
This proactive approach improves the user experience and reduces friction in getting the information they need.
5. Consider new types of transactional messages
In addition to classic confirmation or welcome messages, consider sending proactive emails based on your users' behaviors. For example, if a customer has not logged in to your platform for a week, you can send him a reminder message with special benefits or reminders of his interests.
This type of communication allows you to identify areas for improvement and reactivate users who may have disconnected due to a lack of incentives. But keep in mind that frequency is key: avoid sending too many messages so as not to generate saturation.
Example of an effective transactional message
A good example of a transactional message is Amazon's, which includes:
- Personalization with the user's name.
- Clear information on order status and tracking options.
- Complementary product suggestions based on recent purchases.
- Visible action buttons for the customer to ask questions or rate their experience.

Another outstanding case is Uber, which details the cost of a trip with information on distance, route and time. It also includes a clear call to action to rate the service before booking another trip.

In conclusion, transactional messages are an opportunity to strengthen your relationship with customers and offer them a personalized experience that builds trust and loyalty.
