• Google Workspace / Gmail

1. Navigate to the WP MAIL SMTP > General page.
2. Fill in the following fields:
   • From Email - Enter the Google email you wish to send FROM
   • Force From Email - Check this box
   • From Name - Enter a name you'd like to appear as being sent FROM
   • Force From Name - Check this if you wish to force the FROM name
   • Return Path - Check this box
3. Choose Google / Gmail under the Mailer section.
4. Fill in the following fields:

   These credentials were created in Step 1 above.

   • Client ID - This is a string of letters and numbers you created in your Google account.
   • Client Secret - This is a string of letters and numbers you created in your Google account.
   • Authorized redirect URI - You will input this into your Google account.
5. Click Save Settings.

The instructions above add your Google credentials to the WordPress dashboard. The plugin recommends adding code to your wp-config.php file to further secure your credentials. View the following page for further details.

Adding the constants to your wp-config.php file

3. Scroll down in this file to the following line:

   /* That's all, stop editing! Happy blogging. */

4. Add the following lines just above this line.

   define( 'WPMS_ON', true );
   define( 'WPMS_GMAIL_CLIENT_ID', '********************.apps.googleusercontent.com');
   define( 'WPMS_GMAIL_CLIENT_SECRET', '**********************');
   define( 'WPMS_MAILER', 'gmail' );
   

   The only parts you need to change are WPMS_GMAIL_CLIENT_ID and WPMS_GMAIL_CLIENT_SECRET

5. Save the file.

If you view the plugin page now, you'll see your credentials are not accessible.
