Is Easy WP SMTP Compatible With My WordPress and PHP Version?

10 threads Sep 16, 2025

Content

One of the most common questions users have about the Easy WP SMTP plugin is whether it's compatible with their specific version of WordPress or PHP. This concern is often triggered by a WordPress admin notice stating the plugin "has not been tested with your current version of WordPress." This guide will help you understand plugin compatibility and how to proceed safely.

Why You See the "Not Tested" Warning

WordPress.org displays a warning when a plugin's metadata (the "Tested up to" field in its readme file) hasn't been updated to match the latest core WordPress release. It is an automated notice, not a definitive statement on compatibility. The Easy WP SMTP team often confirms full compatibility with newer WordPress versions even before this metadata is updated in the next plugin release.

Official Compatibility Information

Based on support thread responses from the plugin's team:

  • WordPress: The plugin is consistently confirmed to be compatible with the latest WordPress versions, including 6.4.1, 6.5.3, and 6.8.1. The team addresses the "Tested up to" notice in subsequent updates.
  • PHP: The plugin supports PHP 7.4 and higher. The team has stated that there have been no widespread reports of issues with PHP 8.0, 8.1, or 8.2.
  • Multisite: The plugin works in a WordPress Multisite environment. However, SMTP settings must be configured individually for each subsite within the network.

How to Safely Test Compatibility on Your Site

While the plugin is generally compatible, every website's environment is unique. Follow these steps to test safely before updating PHP or WordPress on your live site:

  1. Create a Backup: Always create a full backup of your website's files and database before making any changes.
  2. Use a Staging Site: The safest method is to test on a staging or development site, which is a clone of your live website. Most hosting providers offer tools to create a staging site easily.
  3. Update and Test: On your staging site, update WordPress to the latest version and/or change the PHP version to your target version (e.g., PHP 8.2).
  4. Perform Critical Tests:
    • Navigate to the Easy WP SMTP settings page to ensure it loads correctly.
    • Send a test email from the plugin's tool.
    • Check that other core site functions, like form submissions and user registrations that send email, are working properly.
  5. Report Any Issues: If you encounter a problem, note the exact error message and the steps to reproduce it. You can then report these findings to help the community.

By following this process, you can confidently maintain your site's security and performance with the latest software while ensuring the Easy WP SMTP plugin continues to function flawlessly.
