WordPress Mail SMTP Plugin
Are you facing the WordPress not sending emails issue❓Don’t worry! Install the Post SMTP Plugin aka (WordPress mail SMTP plugin), for smooth WordPress email deliverability.
Over 400,000 website owners use Post SMTP daily to send WordPress emails securely and reliably💯 using Gmail SMTP, Microsoft Office 365/Outlook, and other SMTP integrations.
Post SMTP is a free, next-generation WordPress SMTP plugin that improves email deliverability for your WordPress site.
The best part is that the Post SMTP plugin helps you configure any SMTP mailer, including Gmail one-click setup and Microsoft Office 365 (formerly Office 365), to prevent spam marking and ensure high email deliverability.
With the ✨Post SMTP Pro version✨, you can unlock even more advanced features, such as detailed email logs, email delivery stats and reporting, Microsoft 365 (formerly Office 365), Amazon SES, Zoho Mail SMTP integration, multiple options for email alerts (i.e., Teams, Webhook, Twilio, and Slack), and much more.
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.
Ultimately, this WordPress SMTP plugin helps you fix all your issues related to WordPress not sending emails.
