Overview

To get your sending off the ground, after you've got your domain added and fully configured, you need to decide which of our two methods you're going to use; SMTP or API. You'll be using one of the two methods to send via our platform using a sending application of your choice.

Note: Since Mailgun does not host mailboxes, our service does not use the POP or IMAP protocols.

Which method works best for you?

Both methods work very well - it's all about what your use case needs happen to be, as well as your personal preferences. At a glance:

SMTP: 

• Flexible with existing applications
• Less technical/coding knowledge not necessary
• Open protocol

API:

• Faster (three times faster!)
• More technical/coding knowledge necessary; 
• No need to craft a MIME (message body) - we assemble it on our side!
• Better for large scale sending; more volume, to more recipients, with less effort

How do I implement my chosen method?

Here's a snapshot of sending via Mailgun with our API:

• Have your API key ready, found in your Mailgun control panel. Need help? Look here
• Your API base url will be 
  • US region: https://api.mailgun.net/v3/YOUR_DOMAIN/
  • EU region: https://api.eu.mailgun.net/v3/YOUR_DOMAIN/
• Check out our libraries for easy integration with Python, Ruby, Java, C# and PHP 

Here's sample code for sending an email with cURL:

curl -s --user 'api:key-3ax6xnjp29jd6fds4gc373sgvjxteol0' \ 
https://api.mailgun.net/v3/samples.mailgun.org/messages \
 -F from='Excited User <excited@samples.mailgun.org>' \
 -F to='devs@mailgun.net' \
 -F subject='Hello' \
 -F text='Testing some Mailgun awesomeness!'

This is of course a quick summary view of the process start to sending; for more information, check out our Quickstart Guide to help get you sending right away!
