Don’t be alarmed because this is a fairly common problem. WP Mail SMTP is essential for reliable email delivery from your website. However, just like any tool, minor problems do occur (that have very quick fixes). In this guide, we’ll walk you through some of the most common problems with WP Mail SMTP to get your test email flying out effortlessly! ## How to Fix WP Mail SMTP Not Sending Test Email Here are some of the most common fixes for WP Mail SMTP not sending test email on your WordPress website: ### 1. Check Your SMTP Mailer Settings Remember, WordPress uses PHP by default for sending emails from your website, which usually doesn’t offer good email deliverability. Therefore, if you’ve installed WP Mail SMTP, but you’re still using the default PHP Mailer, the plugin is not controlling your emails. WP Mail SMTP is compatible with both paid and free [SMTP service providers](https://wpmailsmtp.com/best-smtp-servers/). To select a mailer, go to **WP Mail SMTP » Settings**. ![Additional mailer connections in WP Mail SMTP](https://wpmailsmtp.com/wp-content/uploads/2021/07/Additional-Mailer-Connections.png "Mailer Connections WP Mail SMTP") This is a crucial step because it’s necessary to use a different mailer than PHP for the test and other emails to be sent out successfully. ### 2. Verify All Settings Are Accurate Once you’ve made your choices, there are more settings to be dealt with. Move on to the authentication process by reviewing the documentation in the table below. Mailers available in all versionsMailers in [WP Mail SMTP Pro](https://wpmailsmtp.com/pricing/)[SendLayer](https://wpmailsmtp.com/docs/how-to-set-up-the-sendlayer-mailer-in-wp-mail-smtp/)[Amazon SES](https://wpmailsmtp.com/docs/how-to-set-up-the-amazon-ses-mailer-in-wp-mail-smtp/)[SMTP.com](https://wpmailsmtp.com/docs/how-to-set-up-the-smtp-com-mailer-in-wp-mail-smtp/)[Microsoft 365 / Outlook.com](https://wpmailsmtp.com/docs/how-to-set-up-the-outlook-mailer-in-wp-mail-smtp/)[Brevo](https://wpmailsmtp.com/docs/how-to-set-up-the-sendinblue-mailer-in-wp-mail-smtp/)[Zoho Mail](https://wpmailsmtp.com/docs/how-to-set-up-the-zoho-mailer-in-wp-mail-smtp/)[Google Workspace / Gmail](https://wpmailsmtp.com/docs/how-to-set-up-the-gmail-mailer-in-wp-mail-smtp/)[Mailgun](https://wpmailsmtp.com/docs/how-to-set-up-the-mailgun-mailer-in-wp-mail-smtp/)[Postmark](https://wpmailsmtp.com/docs/how-to-set-up-the-postmark-mailer-in-wp-mail-smtp/)[SendGrid](https://wpmailsmtp.com/docs/how-to-set-up-the-sendgrid-mailer-in-wp-mail-smtp/)[SparkPost](https://wpmailsmtp.com/docs/how-to-set-up-the-sparkpost-mailer-in-wp-mail-smtp/)[Other SMTP](https://wpmailsmtp.com/docs/how-to-set-up-the-other-smtp-mailer-in-wp-mail-smtp/)Though many choices are available, we suggest using [SendLayer](https://sendlayer.com/), [SMTP.com](https://wpmailsmtp.com/go/smtp/), or [Brevo](https://wpmailsmtp.com/go/brevo/ "Brevo(Formerly Sendinblue)") (previously Sendinblue). When it comes to sending [transactional emails](https://wpmailsmtp.com/transactional-email-providers/), these mailers are some of the most reliable choices out there. #### Need a hand? You can purchase White Glove Setup as an additional service with any of our [WP Mail SMTP licenses](https://wpmailsmtp.com/pricing/) and have our customer support team set up WP Mail SMTP for you. Ensure you’re following each step of your mailer setup guide thoroughly and carefully, and check out all values for any typos! ### 3. Choose the Right Email Sender Though many mailers allow you to choose your sender email, not all email addresses work equally well. Ensure you refer to the [guidelines of your chosen mailer](https://wpmailsmtp.com/docs/a-complete-guide-to-wp-mail-smtp-mailers/) for recommendations on the ‘From Email.’ Most mailers and their ‘From Email’ requirements strongly recommend using a domain-specific email for greater reliability. ![configure from email](https://wpmailsmtp.com/wp-content/uploads/2022/12/from-email-primary-connection.png "Configure From Email") ### 4. Use the ‘Force From Email’ Option When you install different plugins, they all might have different [‘From Name’ and ‘From Email’ settings](https://wpmailsmtp.com/how-to-choose-your-from-name-and-from-email/), which may cause issues with deliverability. To fix this, WP Mail SMTP offers an easy solution in the shape of forcing the ‘From Email’ address for all plugins across your WordPress site. Under **WP Mail SMTP » Settings**, there’s an option to ‘Force From Email.’ Activate it to ensure your email plugins have a consistent ‘From Email.’ ![Force From Email in WP Mail SMTP](https://wpmailsmtp.com/wp-content/uploads/2020/02/Force-From-Email-in-WP-Mail-SMTP.jpg "Force From Email WP Mail SMTP") Remember that if the ‘Force From Email’ checkbox is disabled, your chosen mailer is already forcing the ‘From Email’ to be utilized across the website. ### 5. Change the Encryption Method (TLS or SSL) If you’re using Other SMTP to use a transactional mailer service like Mandrill, try changing the encryption method to TLS. It is quite common for the test email and other notifications from your website to fail if the encryption method selected is incompatible with the mailer. Since SSL is becoming obsolete, [using SSL can cause emails to Gmail addresses to be blocked](https://wpmailsmtp.com/fix-gmail-blocking-emails/). To get a better idea about which encryption method you should be using with your mailer, refer to this [detailed guide on SMTP settings](https://wpmailsmtp.com/docs/how-to-set-up-the-other-smtp-mailer-in-wp-mail-smtp/). ![Enter Mailchimp SMTP details into WP Mail SMTP](https://wpmailsmtp.com/wp-content/uploads/2023/10/Enter-Mailchimp-SMTP-details-into-WP-Mail-SMTP.png "Enter SMTP Details WP Mail SMTP") ### 6. Update WP Mail SMTP to the Latest Version It is normal for most plugins, including WP Mail SMTP, that haven’t been updated in a while to start acting up a bit. Therefore, if your test emails are not sending from WP Mail SMTP, make sure you have the latest version installed to rule out any outdated plugin issues. Regular updates provide enhanced functionalities and also resolve pre-existing issues. Just head to **Dashboard » Updates** to see if an update is available. ![Update WP Mail SMTP](https://wpmailsmtp.com/wp-content/uploads/2023/10/Update-WP-Mail-SMTP.png "Update WP Mail SMTP") ### 7. Use the Latest Version of WordPress As important as it is to keep WP Mail SMTP up to date, you should also make sure you have the most recent version of WordPress. To ensure that the plugin is compatible with the most recent version of WordPress, WP Mail SMTP uses the best coding practices. To check if an update for WordPress core is available, log in to your site and go to **Dashboard » Updates**. If you see a notice that reads, “An updated version of WordPress is available,” you might want to update to the latest version. ![Update WordPress website](https://wpmailsmtp.com/wp-content/uploads/2023/10/Update-WordPress-website.png "Update WordPress Version") ### 8. Ensure You’re Running PHP 5.6. or Above Sometimes, it’s the hosting service causing glitches that may prevent the test email from being sent. The WP Mail SMTP plugin requires at least PHP 5.6. However, for optimum performance and security, it’s recommended to have PHP 7.3 or greater, whatever your web hosting service provides. To find out what PHP version your website uses, from your WordPress dashboard, go to **Tools > Site Health > Info > Server**. ![WordPress php version](https://wpmailsmtp.com/wp-content/uploads/2023/10/WordPress-php-version.png "WordPress PHP Version") ### 9. Check for Conflicts with Other Plugins Like any other WordPress plugin that may start malfunctioning due to a ‘conflict of interest,’ having more than one SMTP plugin can cause problems. From your WordPress dashboard, head to the plugins page and ensure only one SMTP-related plugin is active. Deactivate any conflicting plugins! ### 10. Still Facing Issues? Time for Some Help!
