Your message wasn't delivered because the recipient's email provider rejected it

Sending an email is usually a quick and efficient way to communicate, but sometimes it can be a bit more complicated than we'd like. One common issue that email users face is receiving an error message that says, "Your message wasn't delivered because the recipient's email provider rejected it."

This error message is usually found in the subject of an email, which is vague and not very informative. Typically, there is an error code associated with a small phrase within the body of the email, specifying the reason for the error.

If you find the error code and phrase, we recommend that you search for them on our BookStack. We might already have a dedicated page for that specific error that can provide you with more detailed information. However, if you don't find what you're looking for, please read more about the common reasons for email rejection on this page.

We hope this points you in the right direction to understand why your email might have been rejected, but if you need further assistance, please don't hesitate to contact our support team. We are always here to help.
