How to Send Emails Using Gmail SMTP Server

You can use your free Gmail account to send WordPress emails. However, for better delivery, we recommend using paid G Suite.

With G Suite, you get your own professional branded email address like (name@yoursite.com).

G Suite requires you to add MX records to your domain which means that your email will appear to be from your own domain name which increases authenticity and ensures better delivery.

Okay, the first thing you need to do is introduce and activate the WP Mail SMTP plugin.

WP Mail SMTP is the best WordPress SMTP plugin available. This allows you to easily use any SMTP worker to send WordPress messages with higher delivery capabilities.

We recommend you to buy a paid plugin called WP Mail SMTP Pro which gives you access to premium help, more mailers, and white gloves prepared by one of their specialists.

Once activated, you need to visit the Settings » WP Mail SMTP page to set the plugin settings.

Seting WP Mail SMTP plugin

To get started, you need to make sure that you use your Gmail email address in the ‘From Email’ field. Then, you need to provide the sender’s name.

The WP Mail SMTP plugin offers two different ways to associate your WordPress site with Gmail workers.

The first step is using OAuth Authentication. This is a more secure method of sending messages using Gmail workers.

The next step is to physically enter Gmail’s SMTP settings. This technique is not recommended because it is not safe.

Therefore, we have to set up WordPress to use Gmail’s SMTP for sending messages.

Way recommended for all clients. It’s safer and when you set it up, you don’t have to redo it.

You should start by selecting Gmail as your mailer and setting the return method to match the sender.

Troubleshooting Gmail SMTP Not Working Issues

We have seen users encounter few issues when using Gmail SMTP with certain shared hosting configurations.

Take the following steps to fix the Gmail SMTP issue:

  1. Log in to your cPanel account and create an email account that matches your Google apps email address. This might seem strange because you’re not using your server for emails. This step basically tricks your server into believing that you’re sending the email through the server.
  2. In your cPanel account, go to the MX Records and change the MX routing from automatic to remote. It might be a little tricky to find since each host now has a custom cPanel interface. You need to look for a small link next to MX that says Email Routing: Remote Mail Exchanger.
  3. After that log back into your WordPress site and send a test email.
