What is SMTP?
SMTP (Simple Mail Transfer Protocol) is an industry-standard for sending emails. Proper SMTP configuration helps increase email deliverability by using authentication.
Popular email clients like Gmail, Yahoo, Office 365, and Zoho are in a constant battle with email spammers. One of the things they look at is if an email is originating from the location it claims to be originating from.
If the proper authentication isn’t there, then emails either go in the SPAM folder or worse, don’t get delivered at all.
This is a problem for a lot of WordPress sites because, by default, WordPress uses the PHP mail function to send emails generated by WordPress or any contact form plugin like WPForms.
The issue is that most WordPress hosting companies don’t have their servers properly configured for sending PHP emails.
The combination of the two causes your WordPress emails to not get delivered.
How does WP Mail SMTP work?
WP Mail SMTP plugin easily resolves email delivery problems by improving and changing how your WordPress site sends emails. We reconfigure the wp_mail()
function to either use proper SMTP host credentials or leverage a built-in SMTP mail provider.
When using one of our built-in SMTP mail provider integrations (recommended), emails are sent using the provider’s direct API. This means even if your web host is blocking SMTP ports, your emails still sent successfully.
This helps you fix all WordPress not sending email issues.
