Troubleshooting - Email notifications from WordPress not sent or marked as spam
If you use email notifications from your forms, it can happen those are not sent properly, or marked as spam. This article contains some troubleshooting for this.
Check your plugin version
First of all, check which version of the Tripetto plugin you're on. You can find which version you're on the Plugins section in your WP Admin. Check our article on updating the plugin if you're not on the latest release version.
Background of possible issues
Tripetto offers a few possibilities to send mails:
- Automated email notification of new entries;
- Emails from the form itself, created with the send email block.
As every WordPress instance is different (from server setup to plugins and themes), Tripetto follows the WordPress standards regarding email functionality: the
By default, the
wp_mail() function of WordPress uses the PHPMailer function to create and send unauthenticated emails from the webserver. This can result in delivery issues because it does not comply with current standards.
Issues with the default WordPress mailer function can be caused by:
- An incorrect or non-existing WordPress mailer configuration;
- Your hosting platform not allowing the use of PHP for sending emails;
- Incorrect or non-existing DNS records, resulting in your webserver not being allowed to send emails on behalf of your domain;
- The use of an out-of-date or misconfigured plugin that replaces the default WordPress mailer function.
You can try the following to solve issues:
- Make sure your WP installation is able to send mails using the default WordPress mailer function the correct way;
- Install, activate, and configure a plugin that replaces or extends the default WordPress mailer function. Most plugins use secure SMTP with authentication. Some plugins offer OAuth2.0 for authentication.
- Or use the WordPress API and extend the
wp_mail()function to configure secure SMTP with authentication.
Keep in mind that some solutions will store your email account details to either wp-config or the database, making it a potential risk when your website/web server gets compromised.
