Supported PHP Versions for WP Mail SMTP

If you were linked to this page from your WordPress dashboard, then it means that you’re running an outdated version of PHP.

PHP is the programming language that WordPress and WPForms are built on. The version that is currently used for your site is either insecure or no longer supported.

Newer versions of PHP are both faster and more secure. In fact, the version of PHP your website is using no longer receives security updates, which is why we sent you the notice.

The easiest way to resolve this issue is to contact your web hosting provider and ask them to update the PHP version on your hosting account. This actually is very easy to do, and something your webhost should be doing proactively.

However, if your web hosting company is unwilling to upgrade your site’s PHP version, then it clearly shows that they DO NOT care about your website’s security.

In that case, we recommend that you switch to one of the recommended WordPress hosting companies listed on WPBeginner’s article.

At WPForms and WP Mail SMTP, our favorites are Bluehost and SiteGround. Both of them are officially recommended by WordPress, as well. Our own website is hosted with SiteGround.

In case your web hosting company asks, WP Mail SMTP currently requires PHP version 5.6 or higher. However, you should have your web hosting company update your PHP version 7.3 or greater as this is more recent and more secure.
