# Gomail
[](https://travis-ci.org/go-gomail/gomail) [](http://gocover.io/gopkg.in/gomail.v2) [](https://godoc.org/gopkg.in/gomail.v2)
## Introduction
Gomail is a simple and efficient package to send emails. It is well tested and
documented.
Gomail can only send emails using an SMTP server. But the API is flexible and it
is easy to implement other methods for sending emails using a local Postfix, an
API, etc.
It is versioned using [gopkg.in](https://gopkg.in) so I promise
there will never be backward incompatible changes within each version.
It requires Go 1.2 or newer. With Go 1.5, no external dependencies are used.
## 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
## Documentation
https://godoc.org/gopkg.in/gomail.v2
## Download
go get gopkg.in/gomail.v2
## Examples
See the [examples in the documentation](https://godoc.org/gopkg.in/gomail.v2#example-package).
## 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`:
package main
import (
"crypto/tls"
"gopkg.in/gomail.v2"
)
func main() {
d := gomail.NewDialer("smtp.example.com", 587, "user", "123456")
d.TLSConfig = &tls.Config{InsecureSkipVerify: true}
// Send emails using d.
}
Note, however, that this is insecure and should not be used in production.
