We keep getting this error message, can you help?
Message was not executed successfully.
Messenger and Message Type were valid and active, but the messenger send method failed.
The email did not send successfully.
The WordPress wp_mail function is used for sending mails but does not give any useful information when an email fails to send.
It is possible the “to” address ( or “from” address ( is invalid.

Hi there,

EE doesn’t actually send emails itself, it passes them over to wp_mail() which does whatever your server is set up to send the emails.

So the problem your getting is wp_mail() is returning false meaning the email failed to send using the mail server your site it set to use but unfortunately wp_mail() doesn’t return an error we can display.

The quickest way to work around issue with mailservers is to use a transactional email service, we have some listed here:

You sign up to whichever service, install their plugin (which hooks into wp_mail and set it up to use their mail server), add your credentials to the plugin and then test another email.

Another test you can do is install this snippet:

You can add that to a custom functions plugin on your site, we have some documentation on creating one here:

Then the error message you see now should also include some additional details which may help identify the problem, which you can then discuss with your host.
