You can use SendGrid SMTP service to improve your WordPress site email deliverability. SendGrid is one of the leading mailer options for WordPress, SendGrid is reliable and easy to set up. In this article, you will learn how to set up and configure the SendGrid driver with Fluent SMTP.
Configuring Fluent SMTP for SendGrid #
Hover over Settings on the WordPress Admin panel and go to Fluent SMTP Dashboard. If this is the first time you are using Fluent SMTP and haven’t set up any connection yet, you will see the list of available Mailers, as we will work with SendGrid, select SendGrid from the list.

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

Sender Settings #
Now we will need to configure the sender details. Fill up the “From Email” and “From Name”
From Email: The “From Email” should be the email you verified with SendGrid. Check the box to set the return path to match the Mail From. The Return Path indicates where non-delivery receipts or bounce messages are to be sent. If unchecked, bounce messages will 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. You can use a combination of your name and company name. For example, I would choose something like “Jafor From WPManageNinja” where Jafor is the name and WPManageNinja is the company. The API key will be provided by SendGrid.

How to get SendGrid API Key #
Log into your SendGrid account first and then click on the Settings located at the bottom left corner. A dropdown panel will appear and you need to click on the API Keys. Now from the top corner click on the Create API Key.

After getting the API key, go back to Fluent SMTP’s SendGrid configuration panel and enter the API key and Save the Connection Setting. Your SendGrid Driver is ready to send emails from your website.
