Plug-and-Play Email Service for SMTP Integration
Getting your SMTP service set up for transactional emails and email marketing is easy. All you need to do is drop your SMTP credentials into your application, and Mailgun takes care of the rest.
Using an SMTP relay service is the simplest way to get started sending emails. Add and verify your domain name, choose between a dedicated or shared IP address, and then set up your SMTP server. You only need four pieces of information: your username, password, the SMTP server host name, and the SMTP port. Add these into your application’s SMTP configuration settings, and you’re ready to send with Mailgun. Depending on which port you use, you can have either a regular or SSL connection to add security to your email.
Flexible Email API
If you don’t already have a third-party SMTP interface to drop Mailgun credentials into, consider using our HTTP API, which offers more flexibility and better scalability than the SMTP API. Its features give you easy control over your email delivery and email marketing services. Our libraries let developers work in their favorite languages, including Java, C#, Python, Ruby, and more.
Increase your chances of email deliverability success with our SMTP relay and email service. Use SPF, DMARC, and DKIM record customization to authenticate your domain name. Add our email address validation API into your web forms to lower bounce rates and reduce spam complaints. And for a more proactive deliverability solution, our managed email delivery solution provides dedicated, one-on-one support and monitoring to boost your delivery rates even more.
Process Incoming Emails
Receive inbound messages fully parsed in UTF-8 format, with MIME converted to JSON. Mailgun’s email service lets you easily post email content to your application, automate reply handling, route spam into its own filter and more.
Track Email Events
Get detailed logs and metrics on marketing and transactional emails sent through Mailgun’s SMTP server and review specific email events like delivery failures, clicks, and unsubscribes through a simple control panel. Mailgun’s analytics help you analyze A/B tests, understand the effectiveness of your email campaigns, and boost your next send.
Integrate With Your Local Email Server
The best SMTP service offers useful benefits even if you have your own email server. Your application will see better performance because it hands off the sent emails to the local server, while your distribution still gets the benefit of a robust SMTP provider. The email server will handle any connectivity issues, letting you stay focused on application functionality, not error-handling.
