GSuite is a platform of various Google applications that allows us to have email under our own domain. This way we can manage email directly from Gmail, without having to go through redirects to Gmail... and hosting the website on our VPS/Shared Hosting. With this, we can have Gmail emails with our own domain, giving a more professional touch to our emails.

To use the GSuite service on our servers, first you will have to create the GSuite account, add the domain and email accounts. Then, we have to access our Plesk Panel > Subscriptions. We click on the domain we want to modify and access DNS zone settings.

Then, we will have to add the MX records from Google and modify the TXT to allow sending. First, we have to delete the MX records we have on our server, and then we will add the ones from Google, which are the following:

Or we can keep the one we have and only add the following line to the record:
​include:_spf.google.com

After doing all this, we click on the notice that appears on Accept. Then we click on the option Apply DNS template. It would look like this:

To finish configuring it, we must deactivate the email service of our server. To do this, we access the Subscription, and access the Mail tab.
Inside mail, we go to Mail settings. We select the domain, click on the Activate/deactivate services button.
In the tab that opens, we select the option Deactivate in the Mail server option and click on Accept. This way we deactivate the email service of that domain on our server.
