Gomail

Introduction

Gomail is a simple and efficient package to send emails. It is well tested and documented.

It is versioned using gopkg.in so I promise they will never be backward incompatible changes within each version.

It requires Go 1.2 or newer.

Features

Gomail supports:

• Attachments
• Embedded images
• HTML and text templates
• Automatic encoding of special characters
• SSL and TLS
• Sending multiple emails with the same SMTP connection
• Any method to send emails: SMTP, postfix (not included but easily doable), etc

Example

package main

import (
	"gopkg.in/gomail.v2-unstable"
)

func main() {
	msg := gomail.NewMessage()
	msg.SetHeader("From", "alex@example.com")
	msg.SetHeader("To", "bob@example.com", "cora@example.com")
	msg.SetAddressHeader("Cc", "dan@example.com", "Dan")
	msg.SetHeader("Subject", "Hello!")
	msg.SetBody("text/html", "Hello <b>Bob</b> and <i>Cora</i>!")
	msg.Attach(gomail.NewFile("/home/Alex/lolcat.jpg"))

	d := gomail.NewPlainDialer("smtp.example.com", "user", "123456", 587)

	// Send the email to Bob, Cora and Dan
	if err := d.DialAndSend(msg); err != nil {
		panic(err)
	}
}

FAQ

x509: certificate signed by unknown authority

If you get this error it means the certificate used by the SMTP server is not considered valid by the client running Gomail. As a quick workaround you can bypass the verification of the server's certificate chain and host name by using SetTLSConfig:

d := gomail.NewPlainDialer("smtp.example.com", "user", "123456", 587)
d.TLSConfig = &tls.Config{InsecureSkipVerify: true}

Note, however, that this is insecure and should not be used in production.

If you want to support the development of Gomail, I gladly accept donations.

I will give 100% of the money I receive to Enfants, Espoir Du Monde. EEDM is a French NGO which helps children in Bangladesh, Cameroun, Haiti, India and Madagascar. All its members are volunteers so its operating costs are only 1.9%. So your money will directly helps children of these countries.

As an added bonus, your donations will also tip me by lowering my taxes 😄 I will send an email with the receipt of the donation to EEDM annually to all donors.
