This plugin provides a simple emailer.

//ifdef::env-github[] image:[“Travis build status”, link=””] //endif::env-github[]


NOTE: For Play 2.3.x please read[the README on the 2.x branch].

  1. Add a library dependency on play-mailer: +

    "" %% "play-mailer" % "{version}"

    + See below for the version matrix.

  2. Configure the mailer in your conf/application.conf: +

    play.mailer {
    host (mandatory)
    port (defaults to 25)
    ssl (defaults to no)
    tls (defaults to no)
    user (optional)
    password (optional)
    debug (defaults to no, to take effect you also need to set the log level to "DEBUG" for the application logger)
    timeout (defaults to 60s in milliseconds)
    connectiontimeout (defaults to 60s in milliseconds)
    mock (defaults to no, will only log all the email properties instead of sending an email)

You can also configure the mailer programmatically, see[user manual].



import play.libs.mailer.Email;
import play.libs.mailer.MailerClient;
import javax.inject.Inject;
import org.apache.commons.mail.EmailAttachment;

public class MyComponent {
  @Inject MailerClient mailerClient;

  public void sendEmail() {
    String cid = "1234";
    Email email = new Email()
      .setSubject("Simple email")
      .setFrom("Mister FROM <[email protected]>")
      .addTo("Miss TO <[email protected]>")
      // adds attachment
      .addAttachment("attachment.pdf", new File("/some/path/attachment.pdf"))
      // adds inline attachment from byte array
      .addAttachment("data.txt", "data".getBytes(), "text/plain", "Simple data", EmailAttachment.INLINE)
      // adds cid attachment
      .addAttachment("image.jpg", new File("/some/path/image.jpg"), cid)
      // sends text, HTML or both...
      .setBodyText("A text message")
      .setBodyHtml("<html><body><p>An <b>html</b> message with cid <img src=\"cid:" + cid + "\"></p></body></html>");


You need a MailerClient instance to send an email :

import play.api.libs.mailer._
import org.apache.commons.mail.EmailAttachment

def sendEmail {
  val cid = "1234"
  val email = Email(
    "Simple email",
    "Mister FROM <[email protected]>",
    Seq("Miss TO <t[email protected]>"),
    // adds attachment
    attachments = Seq(
      AttachmentFile("attachment.pdf", new File("/some/path/attachment.pdf")),
      // adds inline attachment from byte array
      AttachmentData("data.txt", "data".getBytes, "text/plain", Some("Simple data"), Some(EmailAttachment.INLINE)),
      // adds cid attachment
      AttachmentFile("image.jpg", new File("/some/path/image.jpg"), contentId = Some(cid))
    // sends text, HTML or both...
    bodyText = Some("A text message"),
    bodyHtml = Some(s"""<html><body><p>An <b>html</b> message with cid <img src="cid:$cid"></p></body></html>""")

Since Play 2.4, you can use {runtime-di-uri}[runtime dependency injection] or {compile-time-di-uri}[compile time dependency injection]. As a result, the MailerClient instance can be obtained using runtime dependency injection or compile time dependency injection.

With runtime injection

Use the @Inject annotation on the constructor of your component or controller:

import play.api.libs.mailer._
import javax.inject.Inject

class MyComponent @Inject() (mailerClient: MailerClient)


Configuration will be retrieved each time mailerClient.send(email) is called.

This means that mailer client will always be up to date if you have a dynamic configuration.

With compile time injection

Declare the MailerClient without the @Inject annotation:

import play.api.libs.mailer._

class MyComponent(mailerClient: MailerClient)

Then in your router definition, use the trait MailerComponents:

import play.api._
import play.api.ApplicationLoader.Context
import router.Routes
import play.api.libs.mailer._

class MyApplicationLoader extends ApplicationLoader {
  def load(context: Context) = {
    new ApplicationComponents(context).application

class ApplicationComponents(context: Context) extends BuiltInComponentsFromContext(context) with MailerComponents {
  lazy val myComponent = new MyComponent(mailerClient)
  // create your controllers here ...
  lazy val router = new Routes(...) // inject your controllers here

Finally add this line play.application.loader=MyApplicationLoader in application.conf.


The Play Mailer plugin supports several different versions of Play.
