Mailgun Send Simple Email

See more Mailgun Examples

Send a simple email using Mailgun. Rust

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

let http = chilkat::Http::new();

// Implements the following CURL command:

// curl -s --user 'api:SENDING_API_KEY' \
// 	 https://api.mailgun.net/v3/YOUR_DOMAIN_NAME/messages \
// 	 -F from='Your Name <mailgun@YOUR_DOMAIN_NAME>' \
// 	 -F to='Joe Example <joe@example.com>' \
// 	 -F subject='Hello Joe Example' \
// 	 -F text='Congratulations Joe Example, you just sent an email with Mailgun!  You are truly awesome!'

// Use the following online tool to generate HTTP code from a CURL command
// Convert a cURL Command to HTTP Source Code

http.set_login("api");
http.set_password("sending_api_key");// Replace with your actual sending API key.
