Having trouble sending emails from WordPress using your Gmail or Google Workspace account? We’re here to help! This is a step-by-step tutorial on setting up Gmail or Google Workspace SMTP with WordPress.

Configuring Fluent SMTP with Gmail or Google WorkSpace Emails #

Hover over settings and go to Fluent SMTP Dashboard. If this is the first time you are using Fluent SMTP you will see the list of available Mailer, go ahead and select Google WorkSpace.

If you already have one or multiple SMTP driver setups and now you want to add MailGun also then go to the Settings Tab of Fluent SMTP and select Add New Connection. Now again all the available mailers will appear from where you need to select Google WorkSpace.

Configuring Fluent SMTP for MailGun


After selecting Google WorkSpace as the mailer, a very simple settings window will open as shown on the screenshot below.

Fluent SMTP Google Workspace

In this part, you need to setup “From Email“, “From Name“, “Application Client ID” and “Application Client Secret” and click the save button.

From Email: The “From Email” should be the email you verified with Google Workspace. Check the box to set the return path to match the from. The Return Path indicates where non-delivery receipts – or bounce messages – are to be sent. If unchecked, bounce messages may be lost. With this enabled,
you’ll be emailed using “From Email” if any messages bounce as a result of issues with the recipient’s email.

From Name: From name can be anything you want. The best practice is to use the combination of your name and company name. For example, I would choose something like “Jewel From WPManageNinja” where Jewel is the first name of the CEO and WPManageNinja is the company. The Application Client ID and Application Client Secret will be provided by Google Workspace.
