WP Mail SMTP Alternatives: Are There Better Options?

If you’re looking for alternatives to WP Mail SMTP, there are a few that come close. Let’s take a look.

1. Easy WP SMTP

If you know a little bit about SMTP (Simple Mail Transfer Protocol) and email deliverability, you’ve probably heard of the transactional email provider SendLayer. Easy WP SMTP is a free plugin and a SendLayer product, so you know it’s coming from a reputable company.

We found Easy WP SMTP relatively simple to set up and use. You can configure mailers like SendLayer, Mailgun, Brevo (formerly Sendinblue), and SMTP.com with the free version. If you’re a Pro user, you can also connect your site to the Amazon SES or Microsoft 365 / Outlook mailers.

We liked that you can choose to send emails with a transactional SMTP mailer or an SMTP server, such as Gmail, Outlook, Yahoo, Hotmail, or Zoho Mail. Read this WP Mail SMTP vs Easy WP SMTP comparison for more information.

Additional Features

  • Uses debug logging feature to log failed emails with information about why they failed
  • Gives you standard options to specify reply-to and BCC email addresses
  • Lets you set “From Name” and “From Email,” and allows “Force From Name” and “Force From Email”
  • Easy connection to Gmail to send your WordPress emails in just a few clicks. A great alternative to WP Mail SMTP.


Easy WP SMTP is free to use. There is also a Pro version with additional mailers and advanced email logging that starts at $49 per year.

2. Post SMTP

The Post SMTP WordPress page

Post SMTP is an SMTP mailing plugin that replaces the WordPress PHP mailer with Zend_Mail. This reduces deliverability issues stemming from PHP mail and keeps your emails out of the spam folder.

One of the features we found most helpful in Post SMTP is that, in addition to the setup wizard, there’s also a connectivity test. It scans the SMTP server to detect any firewall blocks or configuration mistakes.

The email log helps you diagnose problems. You can also receive notifications via Slack or Chrome extension.

Additional Features

  • Offers extensions such as Microsoft Office 365, Amazon SES, Zoho Mail, Twilio, and more
  • Increases security with OAuth 2.0
  • Compatible with Contact Form 7, Elementor Forms, Gravity Forms, WooCommerce, and more


There is a limited free version. To access features like the addons, you must either pay for them individually or purchase a membership. Memberships start at $39.99 per year.

3. The Newsletter Plugin

The Newsletter Plugin page on WordPress

The Newsletter Plugin is a little different from others on this list, but it’s a good option if your emails are newsletters.

The Newsletter Plugin is an email newsletter and email marketing system. The main plugin allows you to create drag-and-drop email newsletters. But if delivering those newsletters is the concern, there’s a free SMTP addon.

Additional Features

  • Integrates with Brevo, Amazon SES, SendGrid, SparkPost, Mailgun, and others
  • Connects to WPForms, Contact Form 7, Gravity Forms, Ninja Forms, Elementor Forms, and more
  • Professional setup service


There is a limited free version. For more features and addons, pricing for the premium version begins at $69 with a year of updates and support.

4. FluentSMTP

The FluentSMTP page on WordPress

FluentSMTP is a free and open-source plugin. We found that it offered features that some other platforms include only in pro versions.

For example, more detailed logging gives users a better idea of what their emails are doing. This ultimately helps them create the best configurations for their sites.

Check out this detailed comparison of FluentSMTP and WP Mail SMTP to get a better idea of the features of both plugins.

Additional Features

  • Lets you connect as many email service providers as you want with intelligent email routing
  • Sends daily and weekly notification emails so you can keep up with stats and email failures and diagnose issues
  • Utilize faster and more secure connections with native API integrations
  • Works with Amazon SES, Outlook, Gmail/Google Workspace, Mailgun, Brevo, and more



5. SMTP Mailer

The SMTP Mailer WordPress page

Like others on this list, SMTP Mailer takes control of the wp_mail function in WordPress and uses SMTP instead.

We found that it’s a pretty simple plugin to use. The downside of that is that there aren’t a whole lot of features beyond configuring your site to send emails via SMTP.

There’s also no native support for third-party mailer apps like SendLayer, Brevo, Mailgun, and others.

Additional Features

  • Claims to work with any plugin that uses wp_mail()
  • Has known compatibility with Contact Form 7, Jetpack Contact Form, and Formidable Forms



And there you have it. While we still find WP Mail SMTP to be the most user-friendly mailer plugin, especially for beginners, hopefully this post gave you some insight about similar plugins to help you make the best decision for your site.

If you’re just getting started with learning about how to improve email deliverability from your website, check out these email deliverability best practices.

If you’re looking for the best possible deliverability, note that WP Mail SMTP adds list-unsubscribe headers to all emails sent from WordPress. This is essential, because if your SMTP plugin doesn’t add those headers, you won’t comply with Google’s new sender requirements. We recommend taking a look at these, since it can cause emails to be blocked.
