If you still don't receive email, it means that it's most likely a misconfiguration with your contact form plugin or an incompatibility. You can always ask the plugin developer for help. Let them know that you've performed the test above and the email is working on your WordPress installation itself. Or follow the steps below for some of the more polarizing contact form plugins.

If you are a Kinsta client using HHVM , you can temporarily switch to PHP 7 to test for compatibility issues. You can easily switch to PHP 7 within your MyKinsta dashboard . After testing, you can switch back to HHVM.

For both Kinsta and other host clients, if you're having connection issues you may also need to try an alternate port. Your host could be blocking the port.

Kinsta uses Google Cloud Platform which by default blocks outbound connections on port 25. According to Google, “This outbound SMTP port is blocked due to the high amount of abuse this port is colombia phone number data susceptible to.” In this case, try an alternative port like 2525 . Ports 587 and 465 are open at Kinsta.

3. Your contact form plugin is sending 'fake' emails
If you have performed the test above and your server is configured to send emails, it means there is a problem with the plugin that is sending emails from your WordPress site.


Contact form plugins send emails that are sometimes identified by email clients as fake emails. They are similar to spam emails: email clients will flag them as suspicious.

The reason contact form emails sometimes look fake is that they are sent from a different address than the one added to the From: field in the email you receive.

So if you've set up your contact form to populate the From: field with the email address of the person filling out the form, but the email is actually coming from your WordPress site, then your email client will be suspicious of the email and might flag it as fake.
