WP Mail SMTP Pro unlocks even more powerful features like email logging, advanced email reporting and stats, backup connections, email alerts, smart conditional routing, and much more. What is SMTP? SMTP (Simple Mail Transfer Protocol) is an industry-standard for sending emails. Proper SMTP configuration helps increase email deliverability by adding authentication to the emails sent from your site. Popular email clients like Gmail, Yahoo, Office 365, and Zoho are in a constant battle with email spammers, so they check whether emails are originating from a genuine sender. If the proper authentication isn’t there, emails either go in the SPAM folder or, worse, disappear. This is a problem for a lot of WordPress sites. By default, WordPress uses the PHP mail function to send emails generated by WordPress or any contact form plugin like WPForms. But most WordPress hosting companies don’t have their servers properly configured for sending PHP emails. This is why WordPress emails aren’t delivered. How does WP Mail SMTP work? WP Mail SMTP plugin easily resolves email delivery problems by changing the way your WordPress site sends email. We reconfigure the wp_mail() function to use proper SMTP host credentials or an SMTP mail provider. With our built-in SMTP mail provider integrations (recommended), emails are sent using the provider’s direct API. Even if your web host is blocking SMTP ports, your emails will still be sent successfully. This helps you fix all WordPress not sending email issues.
