What is SMTP, and Why Do You Need It? SMTP, short for Simple Mail Transfer Protocol, is the most widely used protocol for online email transmission. SMTP configuration with proper authentication for your WordPress site ensures that your WordPress emails do not end up in spam. By default, WordPress sends emails using the PHP mail function, which isn’t ideal because most WordPress hosting servers don’t support PHP email. On top of that, most email clients, such as Outlook (Office 365 / Microsoft365), Yahoo, Gmail, Brevo, Zoho, Amazon SES, Mailgun, etc., automatically block or mark spam emails that lack proper authentication. That’s why you need to install the Post SMTP plugin on your WordPress site to configure the SMTP mailer of your choice with one-click SMTP setup for Gmail, Microsoft 365, and more. How Does Post SMTP Work? Post SMTP allows you to easily replace the default PHP mail function (wp_mail) of your WordPress site with the SMTP mailer of your choice, like Microsoft 365(Office 365), Brevo, Zoho, SendGrid, Mailgun SMTP, Gmail (Gmail SMTP Server), Post Mark, Amazon SES etc., which in turn improves WordPress email deliverability. This WordPress mail SMTP plugin provides detailed email logs, email open tracking, email alerts, and a mobile app to monitor WordPress email deliverability. Additionally, with a 3-step setup wizard you can configure any SMTP mailer (e.g., Gmail SMTP (Gmail one-click setup), Microsoft Office 365, Mailgun, Brevo, etc.) securely via API Keys in seconds without providing your SMTP account credentials. NOTE: If you want to set up a Gmail SMTP server for WordPress, check out our detailed guide on how to configure Gmail SMTP server to send WordPress emails reliably.
