If you're receiving this error, it means we have detected potential spam content in this email.
If MailChannels blocks your legitimate email message, an error message is generated and included in the non-delivery report you receive from your mail server.
In this delivery report, you will find a link to MailChannels; click this link to view more information.
On the MailChannled report page, you will see a red Not Spam button.
Click this button to log a false positive report. This will correct the spam filter behaviour so that similar messages will not be blocked in future.
Please note that releasing an email doesn't ensure it will be delivered. The receiving server may also have spam filters, which will also block the email for the same reasons.
You should check the content of the email you are sending before trying again.
