Best Mail Delivery Services for Transactional Emails

Best Mail Delivery Services for Transactional Emails

Transactional emails often do not receive the attention they deserve. However, in most cases, it only requires a little effort to transform them into visually appealing messages that catch the recipients’ attention. And it is a sin to not use the potential of transactional email services because they stand out for their above-average open rate – up to 80 percent.

What obstacles can stand in the way of effectively utilizing such potential? Transactional emails are still most commonly sent from a financial or CRM system that has nothing to do with marketing. In this way, the company loses the enormous marketing potential it could gain with transactional email services.

Thus, marketers can effectively acquire new customers, use increased cross-selling opportunities, and increase sales among existing customers. Many factors contribute to the success of such actions.

One of the most important rules is to avoid “text only” emails – even for simple confirmation emails. Another is to use customer relationships to convince them to recommend your services. One may not forget about clever branding and content personalization.

Email Marketing is a very important area of marketing. To be able to deal with it, you need to get a database of email addresses for potential customers. For this, you should install the appropriate plugins on your website. Find out the best WordPress plugins for email newsletter.

What is a transactional email?

A transactional email is a message sent to the client after a specific action. The best example of a transactional email is a message sent to a mailbox after a purchase. It contains information about the transaction, the product, the price, the shipping status, and more.

The most crucial feature of transactional email service is automation and immediate delivery. Recipients are waiting for these messages, so the delivery should take a few seconds. The transactional email service provider must construct a platform capable of sending such a message without delay and containing all the necessary information about their order.

However, it does not mean that a transactional email has to be a dry and formal message reminiscent of a fiscal receipt. You can convert transactional into promotional emails. In the rest of the article, you will learn how to utilize the potential of a transactional email service.

Engaging with customers through a transactional email

The potential of this tool is not only based on transactional email sending. Formatting transactional email templates attractively, preferably using HTML, is crucial. The email template structure should always refer to the reason for sending the transactional email, as the whole message must be coherent.

It is essential to avoid emphasis on the layout and graphic elements, focusing more on its informational nature. However, the information must be tailored to the customer’s interests and aligned with the email campaign strategy.

A transactional email reaches the recipient at a specific time. In addition to providing written information about the order, it should include call-to-action, graphics, animations, or other similar content related to the customer’s interests.

The marketing strategy should be extensive and composed of many interacting elements. Explore the best small business marketing ideas to create your marketing strategy!


Transactional email services are perfect for upselling additional products to the customer. Your staff may have already made several attempts to upsell, but now, at the time of order summary, is the perfect opportunity to offer accessories that could benefit the customer.

The effectiveness is due to the customer’s emotional state. Immediately after the purchase, they identify with the brand or product and may be more willing to buy something more.

Transactional email templates should encourage customers to make higher-priced purchases. System emails provide an ideal environment in which the benefits of such a purchase can be consistently presented in the appropriate context, effectively stimulating customer interest.

So the transactional email can be the last opportunity to sell a more expensive premium product with a higher margin. Other types of system emails, such as welcome messages, delivery notifications, password resets, and password change requests, have somewhat lower potential for upselling or cross-selling.

What determines the success of a transactional email?

Professional email marketing software

One of the foundations of the success of transactional emails is professional software. It supports sending of the transactional emails and integration with another system (CRM, accounting, or warehouse system) that sends a signal to a transactional email service initiating the mailing process.

A reliable system increases the sender reputation by properly configuring email properties. It also allows you to tailor emails for mobile devices.


A significant problem is the lack of personalization. You must adapt the transactional email content to the recipient. It should be more than just a generic greeting. Focus on the individual characteristics and desires of each client. Consider their order history and cross-selling potential, but don’t forget about the user-friendly interface.

Use dynamic paragraphs, targeting a specific audience based on relevant information. If you address messages individually and emotionally, you will additionally increase the effectiveness of CTA in transactional emails.

You can integrate the transactional email service with other enterprise systems and automate the process. If your support team has to send transactional emails, there may be unnecessary delays, so it’s better to hand over the management of these processes to an automated system.

Also, remember that emails sent in HTML offer significantly more promotional potential. In this way, companies can customize the design of their promotional and transactional emails to match their branding and include personalized graphics that are relevant to each customer.

Adding the company logo in each system email, adding a color-accentuated call-to-action button, or changing the banner depending on the season and characteristics of the customer does not pose any problem. You can search the rich library of templates to construct a transactional email. It is easy-going, and after configuring the settings, every employee can use them, even without special IT skills.

Reliable transactional email delivery software

Regardless of the volume, transactional emails should reach every customer in real-time. The loss of cross-selling opportunities can be more expensive than a monthly subscription to the best transactional email services. That’s why you can’t save to avoid problems related to tool performance and delivery speed.

Effective email deliverability is particularly important for the success of transactional email service because they are sent frequently. Therefore, there is a risk that email service providers and filtering programs can classify notification emails as spam. It means the risk of confronting dissatisfied customers and a decline in sales.

Effective emailing also requires a high-trust mail server to prevent your emails from landing in the spam box. To achieve this, you need to obtain a professional email address sent from a highly reliable server. VPS Europe is definitely such a server. Its high-performance European servers and dedicated IP address will ensure that your email marketing reaches your intended recipient without any issues.

Effective monitoring of success

Similar to professional marketing campaigns based on data, the transactional emails performance in the online business should be measured. Software designed for online stores usually can’t provide valuable email tracking and evaluation of customer response to email communication.

In contrast, marketing emails solutions provide insight and effective evaluation of relevant performance data, such as the number of opens and clicks on individual links.

The Standard plan for $20 per month increases the limit to 6000 emails but is almost fully functional. However, segmentation is still simplified, and advanced comparative testing is unavailable.
