A transactional email API for consistent communication

The average number of business emails sent and received per user each day numbers upwards of 122 emails. Yet transactional emails are initiated by user actions. As opposed to other forms of email marketing and bulk email campaigns, transactional emails have a distinct advantage in capturing a reader’s attention. Your customers are waiting to hear from you; don’t miss your opportunity to stand out.

Engage users with transactional email

Common types of transactional email are action emails, email alerts, and billing emails. They include everything from customer purchase receipts to social media account notifications. Other popular transactional emails include password-reset requests and account creation welcome emails. In fact, welcome emails can be a simple way to engage with your audience. According to recent data from Experian Marketing Services, welcome emails elicit more than 33% greater engagement with a brand. Despite this user insight, only 57.7% of companies greet new customers this way. While using a simple email service may constrain your business’ ability to communicate with customers around the clock, a transactional email api makes it possible. Whatever your needs, let Mailgun help you increase your user engagement with responsive transactional email that features on-brand messaging.
