$ echo -n 'Hello World' | mailgun send -s "Test subject" [email protected]

Sending mail via the golang library

package main

import (
    "fmt"
    "log"
    "github.com/mailgun/mailgun-go"
)

// Your available domain names can be found here:
// (https://app.mailgun.com/app/domains)
var yourDomain string = "your-domain-name" // e.g. mg.yourcompany.com

// The API Keys are found in your Account Menu, under "Settings":
// (https://app.mailgun.com/app/account/security)

// starts with "key-"
var privateAPIKey string = "your-private-key"


func main() {
    // Create an instance of the Mailgun Client
    mg := mailgun.NewMailgun(yourDomain, privateAPIKey)

    sender := "[email protected]"
    subject := "Fancy subject!"
    body := "Hello from Mailgun Go!"
    recipient := "[email protected]"

    sendMessage(mg, sender, subject, body, recipient)
}

func sendMessage(mg mailgun.Mailgun, sender, subject, body, recipient string) {
    message := mg.NewMessage(sender, subject, body, recipient)
    resp, id, err := mg.Send(message)

    if err != nil {
        log.Fatal(err)
    }

    fmt.Printf("ID: %s Resp: %s\n", id, resp)
}

Email Validations

package main

import (
    "fmt"
    "github.com/mailgun/mailgun-go"
    "log"
)

// If your plan does not include email validations but you have an account,
// use your public api key (starts with "pubkey-"). If your plan does include
// email validations, use your private api key (starts with "key-")
var apiKey string = "your-key"

func main() {
    // Create an instance of the Validator
    v := mailgun.NewEmailValidator(apiKey)

    v.ValidateEmail("[email protected]", false)
}

Testing

WARNING - running the tests will cost you money!

To run the tests various environment variables must be set. These are:

• MG_DOMAIN is the domain name - this is a value registered in the Mailgun admin interface.
• MG_PUBLIC_API_KEY is the public API key - you can get this value from the Mailgun admin interface.
• MG_API_KEY is the (private) API key - you can get this value from the Mailgun admin interface.
• MG_EMAIL_TO is the email address used in various sending tests.

and finally

• MG_SPEND_MONEY if this value is set the part of the test that use the API to actually send email will be run - be aware this will count on your quota and this will cost you money.
