WordPress Mail SMTP Plugin
Having problems with your WordPress site not sending emails? You’re not alone. Over 2 million websites use WP Mail SMTP to send their emails reliably.
Our goal is to make email deliverability easy and reliable. We want to ensure your emails reach the inbox.
WP Mail SMTP fixes your email deliverability by reconfiguring WordPress to use a proper SMTP provider when sending emails.
Best of all, our easy-to-use Setup Wizard and detailed documentation guide you through the process.
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 worst, 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 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 email. 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 send successfully.
This helps you fix all WordPress not sending email issues.
WP Mail SMTP plugin includes many different SMTP setup options:
- SendLayer (#1 Recommended)
