Free Email API solution

Full transparency into your emails

Mailgun gives you full transparency into your email deliveries with logs and analytics. You can track message performance based on email service providers, device type, and location. This means you can easily evaluate open and click-through rates, assess the importance of designing for mobile devices, and get a higher return the next time you send to your email list. If a delivery failure occurs, we deliver detailed log feedback to diagnose the problem quickly. In addition to providing searchable, real-time logs of event data, you can also make sure you have a valid email address from the start by integrating Mailgun’s email validation API into your web forms.

Enable your brand’s legitimacy

With Mailgun, companies are empowered to send their emails straight to the inbox through various email authentication protocols. Protect your sender reputation by sending with SPF, DKIM, and DMARC protocols and keep bad actors from impersonating your brand.
