Best Transactional Email Software

Transactional email software refers to software that sends emails in response to pre-established actions taken by recipients. These products send email notifications in response to users’ actions; some examples include a welcome email after creating a new social media account, an email receipt from an e-commerce transaction, or an email for a new newsletter subscription. Businesses use these tools for automating personalized emails as transactions occur. Teams use transactional email software to track metrics such as emails sent, received, opened, and bounced. Transactional email tools are useful to for customer retention, sales, marketing, and public relation teams. Transactional email software integrates with additional types of software, such as CRM, email marketing, and e-commerce products, to maximize the benefits to your business.

Provide automated email response tools

Learn More About Transactional Email Software

What is Transactional Email Software?

The average inbox receives dozens of automated emails a day. This includes everything from order confirmations to promotional emails. A transactional email service facilitates courtesy messages, signup campaigns, and other email communications that do not require a great deal of personalization. Transactional messages fill the need for generic, bulk emails for basic customer events, in between more interpersonal conversations. This automation is valuable for nurturing relationships with customers.

In addition to basic email automation, the tools in this category often generate valuable insight from recipients. Measuring details such as click-through rates of emails encourages marketing and customer service teams to continuously refine their messaging for improved end results (e.g., subscriptions, purchases, etc.). A transactional email service has a dual purpose of sending emails and drawing conclusions from their performance.

Key Benefits of Transactional Email Software

  • Automatically sending large volumes of email
  • Using a trusted server to ensure emails are bypassing spam filters and are successfully delivered
  • Tracking key metrics to see if a strategy is working successfully
  • Providing another platform to market a product
  • Building trust with customers by providing an official transactional email receipt

Why Use Transactional Email Software?

Email messaging is not something to be taken lightly. Today, this form of communication is one of the most effective methods that customers use to interact with businesses. A busy organization can ensure a steady flow of emails at every opportunity where correspondence is expected while using a transactional email service. Different opportunities include receipts for online purchases or signing up for a newsletter. This helps ease the burden on marketing and customer service teams so they can focus their efforts on high-level strategy and interactions. Beyond this, transactional email delivery provides select features such as marketing analytics software, which generates valuable data including deliverability, timing, and composition of every automated response sent.

Today’s consumers are accustomed to receiving emails at regular intervals throughout their buying journey. These modern email services provide assurance to customers that transactions are successfully processed, acknowledged, and valued by a business. This plays a significant role in brand reputation and customer satisfaction. A simple email influences important consumer decisions such as subscriptions, renewals, and future purchases. Along the way, analytics features assist with shaping a company’s voice and overall email strategy. Considering the increasing relevance of email communications, continuous improvements translate to desirable results across an entire organization.

Who Uses Transactional Email Software?

How many emails does the average person send a month? 500? 50,000? Transactional email solutions are normally used by companies and users sending a massive number of emails every day. Most users of transactional email tools need them because their servers can't handle the volume of emails they need to send, or their server is flagged by consumers' emails as spam, preventing delivery. Most transactional email tools use a trusted simple mail transfer protocol (SMTP) server—allowing emails to bypass the spam filter—and are built to efficiently support high email volume.

The platforms in this category are often used in conjunction with email marketing software, marketing automation software, or other tools that assist with the delivery of emails. Many products in this category serve multiple functions and exist in more than one software category. Transactional email tools benefit users in charge of customer-facing messaging (e.g., marketing, sales). Development or IT teams may be involved with the setup and modification of these platforms such as configuring SMTP servers and ensuring compliance (e.g., GDPR compliance) with any regulations and general deliverability. The specific uses in an organization vary depending on the size, structure, and responsibilities of a team. This could include anything from establishing email addresses to testing and improving messaging.

Transactional Email Software Features

Deciding on what a company needs out of a transactional email tool determines which is right for that organization. Some transactional email tools are simple solutions for only sending email, while others give a whole dashboard of options. Some solutions even allow users to write lines of code to fully customize their experience. Advanced statistics, notifications, email design, and more are all things to consider before making a transactional email software decision. The following are some features you may come across as you research the diverse offerings in this category

Workflow automation — At any given moment, an established brand can have dozens of automated messages queued up for delivery. These messages serve as appropriate responses to various actions or events in the customer lifecycle. Transactional email services map out responses and automatically send emails when the customer takes the correct course of action. Response flow features within these products are similar to those of chatbots software. In addition to choosing which email to send, these automation workflows help associate sent emails with different domains based on their purpose. Large businesses may have many unique domains for sending emails, and may find a case-by-case effectiveness for different domains after testing the performance of email campaigns.

Email segmentation is a significant component of an automated email sending service, such as those made possible with these products. Segmentation enables businesses to target specific groups of recipients when sending emails, and distribute the most valuable message at the optimal moments. Administrators using these tools adjust segmentation when configuring or editing transactional email workflows, to further streamline the flow of messaging and maximize the ROI potential of each email sent.

Email customization — Transactional emails always contain something unique. This can be the name of the customer or social media user who has signed up for a service or the confirmation on a product purchased through an e-commerce site. Depending on how custom each email needs to be, different transactional email tools help solve these problems. Think about how unique each email sent out needs to be before making a transactional email decision, as certain tools offer more robust customization features than others.

To prepare an email for delivery, platforms often include templates with different email designs, layouts, fonts, and other features. These involve everything from the margins of an email to custom buttons in the messages. In addition to templates, some transactional email apps allow for complete customization from scratch, using a built-in layout tool or an integration with external software. It is important to consider the purpose of each email sent, and use this to inform the design and messaging of the different responses in a workflow. This may mean including different buttons in an email or rearranging the order of email sections based on deliverability analytics.

Email analytics — Transactional marketing relies on continuous improvement to succeed. Several products featured in this category include some degree of reporting capabilities. With these features, businesses can track email after they send it, and capture metrics including open rates, click-through rates, and engagement with each section, link, or button. Analytics also help users identify deliverability issues, so organizations can remedy underlying issues and improve their email services. Certain products include specialized spam filter testing, domain testing, or other tools to ensure maximum deliverability and customer trust with each email sent.

Some transactional email software tools allow split testing to compare the success rate of different versions of the same email. This is also known as A/B testing. The A/B testing features in some products uncover an additional layer of insights to help shape an ongoing email strategy, and make the choices that are most likely to benefit an organization and customers alike. People are constantly flooded with new emails, and it takes a well-thought-out message to be worth their time and consideration. The richer the email analytics, the higher chance of an effective transactional email campaign.

Integrations — Transactional email tools integrate with certain applications, frameworks, and existing email campaigns to execute automated responses to customer actions, capture the appropriate data, and steer customers to their desired outcomes. A few examples of these integrated systems include CRM software, email marketing software, and e-commerce platforms. It is important to research a product’s integrations to see how they align with current technology infrastructure. If a platform does not offer ideal integrations, it may not be used to its full potential. Reach out to the vendor of a given product to ask about integrations, and how to get the most value out of a transactional email service.
