Gmail Mailer Driver

Send email with Gmail using this driver plugin for Winter CMS.

Note: You must use version 1.0.15 with Winter CMS < v1.2.

Note: You must use at least version 1.1.0 with Winter CMS >= v1.2. This version of Winter has introduced changes to the way mail transports are configured (See Installing for more info).

Installing

composer require zaxbux/wn-gmaildriver-plugin

In your Winter CMS config/mail.php, add the gmail transport to the mailers array:

'mailers' => [

	// ...

	'gmail' => [
		'transport' => 'gmail',
	],

	// ...
],

Requirements

• A Gmail account. Google Workspace (G Suite) accounts are also supported, if your administrator has enabled access.
• Gmail API credentials (see below).

Plugin Settings

The plugin is configured in your backend settings. Change the mail method to Gmail in Mail configuration and configure your API credentials. Obtain API credentials from the Google Cloud Console.

Obtaining API Keys

Read instructions on obtaining API keys

Testing delivery

To make sure everything is working, try test sending a mail template to yourself.

Revoking access

In case you want to revoke access, click the Revoke Authorization or Reset to default buttons on the Gmail configuration page. This will delete the credentials and access tokens. You may also want to remove app access on your Google account.

Important Notes

• The Gmail API will only send emails as the account which you granted access with, it is currently not possible to send email as another user.
• The Gmail API has sending limits for free (consumer) and paid (Workspace) accounts.
• You can send email using another email address under your control, using an alias. Learn more about configuring sending aliases in this Google Support article. Change the Sender email in Mail configuration to match your alias. The Sender Name does not have to match and can be whatever you choose.
• The authorization tokens expire if not used for 6 months or if you change your Google account password.

Advanced Usage

This section is for advanced users.

Providing credentials

To provide the OAuth credentials without entering them through the backend UI, you can add them in the config/mail.php file. This is useful if you want to provide credentials using an environment variable. By default, the contents of the GOOGLE_APPLICATION_CREDENTIALS_JSON environment variable will be used.

Example:

'mailers' => [
	'gmail' => [
		'transport' => 'gmail',
		// ...

		'client_id' => '...',      // Your OAuth client ID
		'client_secret' => '...',  // Your OAuth client secret

		// ...
	],
],

Authentication Scopes

To change the authentication scopes (permissions requested from the user), you can override the default scopes in the config/mail.php file. Add scopes to the mail/mailers.gmail.scopes array. For the plugin to function correctly, the gmail.send scope is required (this scope is always included by the plugin). Gmail Auth Scopes

Example:

'mailers' => [

	// ...

	'gmail' => [
		'transport' => 'gmail',
		
		// ...

		'scopes' => [
			\Google_Service_Gmail::GMAIL_READONLY,
		],
	],

	// ...
],
