WordPress SMTP Plugin

Are you dealing with the WordPress not sending emails problem? Post SMTP helps you fix WordPress email delivery by connecting your site to a reliable SMTP or API mailer.

Post SMTP is a free WordPress SMTP plugin that helps you send WordPress emails securely and reliably through Gmail, Microsoft 365, Outlook, Amazon SES, Brevo, Mailgun, SendGrid, Postmark, Zoho Mail, and other supported email service providers.

Beyond SMTP, Post SMTP gives you the tools to monitor WordPress email delivery. Track sent and failed emails with email logs, inspect delivery errors, and get failure alerts when something goes wrong. You can also configure backup SMTP connections to keep your site’s emails moving if your primary mailer becomes unavailable.

With 20+ SMTP and API mailer options, Post SMTP works with the email service you already use. Its monitoring and notification tools help you troubleshoot delivery problems faster and keep important WordPress emails on track.

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.

Why is WordPress not sending emails?

WordPress uses the PHP mail() function by default, which may not provide reliable email delivery. Post SMTP routes your WordPress emails through a trusted SMTP or API mailer such as Gmail, Microsoft 365, Amazon SES, Brevo, SendGrid, Mailgun, Postmark, etc. This can help fix failed or missing WordPress emails and improve email delivery.

How does Post SMTP improve WordPress email delivery?

Post SMTP connects your WordPress site to a dedicated SMTP or API mailer instead of relying on your web server’s default email function. It also provides email logs, delivery error details, backup connections, failure alerts, and even a dedicated mobile app to help you monitor and troubleshoot WordPress email delivery.

Does Post SMTP work with Gmail and Google Workspace?

Yes. Post SMTP supports Gmail and Google Workspace. You can connect your account using Google’s supported authentication method, such as OAuth 2.0, and send WordPress emails through your Gmail or Google Workspace account. Post SMTP also offers Gmail One-Click Setup.

Does Post SMTP support Microsoft 365 and Outlook?

Yes. Post SMTP supports Microsoft 365 and Outlook. You can connect your account using Microsoft’s supported authentication method, such as an Application (Client) ID and Client Secret, or use Post SMTP’s Microsoft One-Click Setup to connect your account and send WordPress emails through Microsoft 365.

Does Post SMTP work with WooCommerce?

Yes. Post SMTP works with WooCommerce and can deliver transactional emails generated by your store, including order notifications, customer emails, password resets, and other WordPress emails.

Does Post SMTP support Contact Form 7?

Yes. Post SMTP works with Contact Form 7 and other WordPress form plugins. Once you configure a supported SMTP or API mailer, Contact Form 7 emails can use that connection instead of your site’s default email function.

Can Post SMTP log WordPress emails?

Yes. Post SMTP includes email logging tools that let you review WordPress email activity and troubleshoot failed messages. Depending on your Post SMTP plan and configuration, you can access additional email log features such as ‘Set email logs retention period’.

Can Post SMTP resend failed emails?

Post SMTP provides tools to troubleshoot failed emails, and supported Pro features let you resend failed messages from the email logs. Check the current Pro feature list for the latest availability.

Does Post SMTP support backup SMTP connections?

Yes. Post SMTP supports backup or fallback connections that can help keep your WordPress emails moving when your primary mailer fails. You can configure an additional mailer as a backup connection to improve email reliability.

Can I receive email failure alerts?

Yes. Post SMTP can notify you when WordPress email delivery fails. It supports multiple notification options, including email, Slack, SMS via Twilio, mobile app, push notifications through webhooks and the Chrome Extension, and other supported notification channels. These alerts help you spot email delivery problems quickly and act before they affect your users.

Is Post SMTP free?

Yes. Post SMTP offers a free version that provides SMTP and supported mailer connections for WordPress email delivery. Post SMTP Pro adds premium SMTP Mailers with One-Click Setup, advanced features for email logs, monitoring, reporting, alerts, email open tracking, and other advanced email-management needs.

What is included in Post SMTP Pro?

Post SMTP Pro offers premium mailer options, One-Click Setup for Gmail SMTP and Microsoft 365 SMTP, and advanced email delivery and monitoring capabilities to the free plugin. Depending on the current Pro release, features can include advanced email logs, email quota scheduling, additional monitoring (email open tracking) and reporting tools, enhanced notifications, email resending, and other premium functionality.

Which email providers does Post SMTP support?

Post SMTP supports 20+ SMTP and API mailer options, including Gmail, Google Workspace, Microsoft 365, Outlook, Amazon SES, Brevo, Zoho Mail, Postmark, Mailgun, SendGrid, SMTP.com, Cloudflare Email Service, and other supported providers. Available mailers can change as Post SMTP adds or updates integrations.

How do I migrate from another SMTP plugin to Post SMTP?

You can migrate to Post SMTP by installing the plugin, selecting your email provider, and configuring the required SMTP or API connection. After setup, send a test email and check the email logs to confirm delivery. If you are migrating from another SMTP plugin, review your existing mailer settings and credentials before switching.

What is OAuth 2.0?

A modern replacement for traditional password-based authentication. Post supports the OAuth 2.0 implementations of all three major e-mail providers: Gmail, Office365, Brevo, Mailgun, 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 SMTP, 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

NEVER give out your Gmail, Microsoft or Yahoo password to a 3rd-party or 3rd-party program that you don’t fully trust.

Can I use this plugin to send via Outlook, Microsoft 365, Gmail SMTP, Zoho, Yahoo, or SendGrid SMTP?

Yes! With the Post SMTP Plugin, you can configure any SMTP mailer account, including Brevo, Mailgun, and SendGrid on 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!)
  1. Go to Microsoft account Developer Center and select ‘Create application’.
  2. In the ‘Application name’ field, enter ‘Post SMTP’. Select ‘I accept.’
  3. Select ‘API Settings’ from under ‘Settings’.
  4. In ‘Redirect URL’, enter the redirect URI given by Post (either from the wizard or from the manual configuration page). Select Save.
  5. Select ‘App Settings’ from under ‘Settings’.
  6. Enter the Client ID and Client Secret displayed here into the Post’s settings page.
How do I get a Yahoo Client ID? (For Yahoo Mail users only!)
  1. Go to Yahoo Developer Network and select ‘Create an App’.
  2. In the ‘Application Name’ field, enter ‘Post SMTP’. For ‘Application Type’, choose ‘Web Application’.
  3. In ‘Home Page URL’, enter the ‘Home Page URL’ given by Post.
  4. In ‘Callback Domain’, enter the ‘Callback Domain’ given by Post.
  5. Under ‘API Permissions’, choose ‘Mail.’ Under ‘Mail’ choose ‘Read/Write’
  6. Click ‘Create App’
  7. Enter the Client ID and Client Secret displayed here into the Post’s settings page.
How can I revoke Post’s OAuth 2.0 access?
