Are you facing the WordPress not sending emails issue? Don’t worry! Install the Post SMTP Plugin for smooth WordPress email deliverability.
Over 300,000 website owners use Post SMTP daily to send WordPress emails securely and reliably????.
Post SMTP is a free and next-generation WordPress SMTP plugin that has everything you need to improve the email deliverability of your WordPress site.
The best part is that the Post SMTP plugin helps you configure any SMTP mailer with proper authentication that guarantees the delivery of your WordPress emails and prevents them from being marked as spam.
With the Post SMTP Pro version, you can unlock even more advanced features, such as detailed email logging, email delivery stats and reporting, Microsoft 365, Amazon SES, Zoho SMTP integration, multiple email failure alert options, and 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 (Microsoft 365), Yahoo, Gmail, Zoho, 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.
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, Brevo, Zoho, Gmail, Post Mark, etc., which in turn improves WordPress email deliverability.
Additionally, with a 3-step setup wizard using OAuth (open authentication), you can configure any SMTP mailer securely via API Keys in seconds without providing your SMTP account credentials.

A modern replacement for traditional password-based authentication. Post supports the OAuth 2.0 implementations of all three major e-mail providers: Gmail, Hotmail and Yahoo Mail.
How does OAuth 2.0 work?
Post requests a limited access OAuth 2.0 token (valet key) to access the APIs (enter the house) and perform a specific service (handle Gmail, stay out of Google Docs) with no need for you to surrender your username and password credentials (master house key).
Once access is granted, Post commandeers the WordPress wp_mail() function to provide an incredibly stable mail sub-system.
There are many reasons why OAuth 2.0 is better than any password-based mechanism:
Post will never ask for your password, so your password can’t be stolen
If you change your password regularly, you will never have to update Post’s configuration
You have tighter control over the data Post has access to. For Google users, it can never access your Calendar or Docs or YouTube; for Yahoo users, it can never access your Flickr
If your WordPress site gets hacked, you can revoke Post’s email access without impacting any other application or website that has access to your account
Can I use this plugin to send via Outlook, Microsoft 365, Gmail, Zoho, Yahoo, or SendGrid SMTP?
Yes! With the Post SMTP Plugin, you can configure any SMTP mailer account with your WordPress site. Check out our detailed SMTP configuration documentation for all major SMTP service providers.
What is a Client ID?
To use OAuth, your website needs its own Client ID. The Client ID is used to control authentication and authorization and is tied to the specific URL of your website. If you manage several websites, you will need a different Client ID for each one.
How do I get a Microsoft Client ID? (For Hotmail/Live/Outlook.com users only!)
