SMTP sending made painless
Managing your own SMTP servers can be time-consuming and costly. Whether you’re looking to cut back on ownership costs or future-proof your email program, a cloud-based SMTP service is a great solution.

Understanding SMTP: what is an SMTP server?
A Simple Mail Transfer Protocol (SMTP) is a form of communication between servers used to send and receive email. SMTP servers require authentication in the form of a username, password, IP address, ports, and security protocol (typically SSL or TLS). It’s easy to start sending via your application's SMTP email client. Need a little extra help? Consult our SMTP documentation.
While SMTP servers are an easy way to send outgoing mail, we recommend switching over to an Email API if your systems can support the migration. Email APIs can process requests faster than a typical SMTP service and are easier to scale should your email volume grow over time.
Send emails to the inbox
Secure your SMTP email streams and keep spammers from spoofing your brand with proper authentication protocols. With protocols like SPF, DMARC, and DKIM records, you’ll not only improve the reputation of your brand with recipients but with inbox service providers too. Using these methods alongside solutions like our Email Address Validations, Inbox Placement Testing, and Send Time Optimization lowers your spam rate, reduces spam complaints, and improves your overall email deliverability.
Need a more proactive approach and a helping hand? Our Deliverability Service pairs you with a Technical Account Manager who will advise you along the path to email sending success.
Easy to read incoming messages
Configure your SMTP setup and clean up your inbound email streams with routes. Routes allow senders to clean up cluttered email threads by fully parsing your inbound messages and converting them to UTF-8 for easy reading. Turn complex MIME data from incoming messages into straightforward JSON, making inbound processing a breeze for any business.
Pair with your local SMTP email server
An SMTP email service offers useful benefits even if you have your own email server. As a result of pairing an SMTP service with internal servers, 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. Whether you need to send one thousand or 10 million emails in minutes, Mailgun’s email infrastructure boasts 99.99% server uptime – so you’re never caught in a bind when you need it most.
Looking for a place to get started? Mailgun's documentation covers popular programming languages like Python, Ruby, Java, C# to make implementation as painless as possible.
