Class MailApp

Sends email.

This service allows users to send emails with complete control over the content of the email. Unlike GmailApp, MailApp's sole purpose is sending email. MailApp cannot access a user's Gmail inbox.

Changes to scripts written using GmailApp are more likely to trigger a re-authorization request from a user than MailApp scripts.

`sendEmail(message)`

Sends an email message. This variation of the method is much more flexible, allowing for many more options.

// This code fetches the Google and YouTube logos, inlines them in an email
// and sends the email
function inlineImage() {
  var googleLogoUrl = "https://www.gstatic.com/images/branding/googlelogo/1x/googlelogo_color_74x24dp.png";
  var youtubeLogoUrl =
        "https://developers.google.com/youtube/images/YouTube_logo_standard_white.png";
  var googleLogoBlob = UrlFetchApp
                         .fetch(googleLogoUrl)
                         .getBlob()
                         .setName("googleLogoBlob");
  var youtubeLogoBlob = UrlFetchApp
                          .fetch(youtubeLogoUrl)
                          .getBlob()
                          .setName("youtubeLogoBlob");
  MailApp.sendEmail({
    to: "[email protected]",
    subject: "Logos",
    htmlBody: "inline Google Logo<img src='cid:googleLogo'> images! <br>" +
              "inline YouTube Logo <img src='cid:youtubeLogo'>",
    inlineImages:
      {
        googleLogo: googleLogoBlob,
        youtubeLogo: youtubeLogoBlob
      }
  });
}

Parameters

Name	Type	Description
`message`	`Object`	a JavaScript object representing an email message

Advanced parameters

Name	Type	Description
`attachments`	`BlobSource[]`	an array of files to send with the email
`bcc`	`String`	a comma-separated list of email addresses to BCC
`body`	`String`	the body of the email
`cc`	`String`	a comma-separated list of email addresses to CC
`htmlBody`	`String`	if set, devices capable of rendering HTML will use it instead of the required body argument; you can add an optional `inlineImages` field in HTML body if you have inlined images for your email
`inlineImages`	`Object`	a JavaScript object containing a mapping from image key (`String`) to image data (`BlobSource`); this assumes that the `htmlBody` parameter is used and contains references to these images in the format `<img src="cid:imageKey" />` (see example)
`name`	`String`	the name of the sender of the email. Defaults to the sender's username.
`noReply`	`Boolean`	`true` if the email should be sent from a generic no-reply email address to discourage recipients from responding to emails; this option is only possible for Google Workspace accounts, not Gmail users
`replyTo`	`String`	an email address to use as the default reply-to address (default: the user's email address). If `noReply` is set to `true`, `replyTo` is ignored.
`subject`	`String`	the subject of the email
`to`	`String`	the email address of the recipient or a comma-separated list of email addresses to be the recipients
