SMTP (Simple Mail Transfer Protocol) is an industry standard for sending email. Proper SMTP configuration helps increase email deliverability by adding authentication to 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 verify that emails come from a real sender. If they don’t have the proper authentication, the emails either end up in the SPAM folder or worse, disappear. This is a problem for many WordPress sites. By default, WordPress uses the PHP mail function to send emails generated by WordPress or a contact form plugin like WPForms. But most WordPress hosting companies don’t have their servers properly configured to send PHP emails.
