This is an actively maintained fork of Gomail and includes fixes and improvements for a number of outstanding issues. The current progress is as follows:
- Timeouts and retries can be specified outside of the 10 second default.
- Proxying is supported through specifying a custom NetDialTimeout.
- Filenames are properly encoded for non-ASCII characters.
- Email addresses are properly encoded for non-ASCII characters.
- Embedded files and attachments are tested for their existence.
- An
io.Readercan be supplied when embedding and attaching files.
See Transitioning Existing Codebases for more information on switching.
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 requires Go 1.2 or newer. With Go 1.5, no external dependencies are used.
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

See the examples in the documentation.
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/mail.v2"
)
func main() {
d := mail.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.
Contributions are more than welcome! See CONTRIBUTING.md for more info.
