What is a transactional email?

Transactional emails are triggered when a recipient requests a specific action -- like a password reset – and an automated email is sent in response. These automated emails are sent programmatically and contain important information customers need to complete an action, like an order confirmation, customer service response, or account notification.

Mailgun’s robust email API can handle any type of transactional message:

  • Badge Check

How transactional emails improve customer experience

Unlike email marketing campaigns -- or commercial emails -- which are sent to a large group of subscribers, transactional emails are anticipated, personal, and relevant. That’s why they lead to better open rates, engagement rates and deliverability than most marketing emails. Transactional emails are an integral part of the customer journey and are vital for completing workflows quickly. They also keep customers safe, with security alerts, new device notifications, and other built-in reminders that protect accounts and prevent fraud. That’s probably why 71% of consumers are willing to search spam folders for transactional emails.

Transactional email vs. marketing email

Transactional messages are triggered in real-time by a specific user action, and they’re sent on a one-off, individual basis. Email marketing campaigns, on the other hand, are one-to-many communications promotional emails that promote a product, service, sale, or other events. Although a user has opted-in to receive this communication as subscribers, these marketing emails are usually not user-driven in the same way transactional emails are. Since the best transactional emails contain information a user specifically requested, they tend to have much higher open rates than email marketing campaigns, and thus have better email deliverability.

Why you need a transactional email service

From account creation to customer support and password resets to order confirmations, customers have come to expect a real-time inbox delivery almost every time they interact with an online brand. When a customer’s action triggers a brand’s site to send email, those emails are known as transactional emails. Unlike other types of email marketing and marketing email campaigns, transactional emails have incredibly high open rates — for a reason. The customer is expecting this kind of correspondence, and missing a popular transactional email may even confuse and frustrate them.

How to send transactional emails

If transactional emails establish and guide the customer relationship, developers must do everything in their power to make sure that email delivery doesn’t get snagged in a spam folder or thwarted by the email delivery send limits set by Google and other email hosts. Building and maintaining your own SMTP server is one option, but most developers would rather avoid the hassle, expense and security risk. Instead, they send emails by SMTP relay or API through a cloud-based, third-party email service. Mailgun’s transactional email service allows you to send emails in real time with the highest delivery rates and lowest fear of spam folders or send limits.
