Configuring Simple Mail Transfer Protocol (SMTP) in WordPress is essential for ensuring reliable and efficient email delivery. While many WordPress users rely on plugins for SMTP setup, it’s also possible to configure SMTP without using a plugin. In this comprehensive guide, we’ll take you through the steps to set up SMTP in WordPress without the need for additional plugins. By the end, you’ll have a streamlined email delivery system that enhances your website’s communication capabilities.

Step 1: Choose a Reliable SMTP Service Provider: To configure SMTP in WordPress, it’s important to select a dependable SMTP service provider. Popular options include SendGrid, Gmail, and Mailgun. Consider their features, pricing, and delivery reputation to choose the provider that best suits your needs.

Step 2: Obtain Your SMTP Credentials: Once you’ve selected an SMTP service provider, create an account and obtain your SMTP credentials, including the SMTP server address, port number, username, and password. These credentials will be used to connect WordPress with the SMTP service.

Step 3: Edit the wp-config.php File: Access the wp-config.php file in your WordPress installation directory. Add the following lines of code before the line that says “That’s all, stop editing! Happy blogging.”

sqlCopy code
// SMTP configuration
define( 'WPMS_ON', true );
define( 'WPMS_SMTP_HOST', 'your_smtp_server_address' );
define( 'WPMS_SMTP_PORT', 'your_smtp_port_number' );
define( 'WPMS_SSL', false );
define( 'WPMS_SMTP_AUTH', true );
define( 'WPMS_SMTP_USERNAME', 'your_smtp_username' );
define( 'WPMS_SMTP_PASSWORD', 'your_smtp_password' );

Replace the placeholders with your actual SMTP server address, port number, username, and password obtained from your SMTP service provider.

Step 4: Test the SMTP Configuration: To ensure that your SMTP configuration is working correctly, send a test email from your WordPress site. Choose a reliable email address to receive the test email and confirm its successful delivery. If the email is received, your SMTP configuration is set up correctly.
