Transactional emails are not just regular emails but ones with high open rates, up to 50%, and click-through rates averaging 4.8%. For comparison, non-transactional messages have a CTR of only around 3.1%.

Transactional emails vividly demonstrate your interest in solving your consumers’ problems, satisfying their cravings, and making them happier, all boosting your brand reputation and growing your bottom line

But we’re getting ahead of ourselves a little. Before we dig into the depths of transactional emails, let’s find out what they are and what makes them different from regular emails. Then, having this knowledge, we can review the most effective tools to write a compelling transactional message. 

Without any further ado, let’s dig into it.

What is a Transactional Email?

Transactional emails are messages triggered by a user’s action or an event, for example, an order confirmation email. These emails provide information necessary to complete a transaction or some other target action.

What is transactional email?

As a rule, transactional emails contain:

  • Payment details
  • Product info
  • Notifications about order status, payments, password changes, etc.
  • Transaction receipts
  • Messages about payment errors
  • Subscription notices
  • Confirmation emails

Transactional emails are a convenient and reliable way to establish customer trust. For instance, an email with detailed information about the journey of an ordered product from your warehouse to the delivery address will present you as a professional, convincing the recipient that you value their trust and adhere to a policy of transparency and honesty towards your buyers.

Transactional Emails vs. Marketing Emails

Marketing emails are messages that:

  • intended for a large number of consumers
  • sent at the same time
  • include advertising elements or consist entirely of promotional offers

How New Brands can Engage their Early-Stage Email Subscribers 

In contrast to transactional notifications, marketing texts are aimed at brand promotion, attracting customers, and prompting the recipient to take a specific action: visiting a website, signing up, making a purchase, etc. 

Transactional vs. Marketing Emails

Characteristic    Transactional emails Marketing emails
Content Information (sometimes with ad elements) tailored individually to each recipient      Promotional content identical for each recipient
Purpose Action confirmation and providing data necessary for further collaboration Brand promotion and selling a specific product or service
Sending Automatically generated and sent upon user request or interaction Can be sent at any time
Audience Only users who triggered an email by their action The entire target audience of the brand, including cold and warm leads


Important note: According to the legal norms of certain countries, marketing emails can only be sent to customers who have given explicit permission to receive promotional communications. Therefore, if your emails contain advertising elements, pay attention to the jurisdiction of the country in which you operate.
