# Why am I seeing an email address rejection message?

If you see a message like this when attempting to send an email:

<figure><img src="/files/2PQNtCFCBqExuZIxkjRo" alt=""><figcaption></figcaption></figure>

This means that the email address you are trying to send the message to is considered inactive by the sending mechanisms. This happens when:

* The email address no longer exists.
* The recipient has reported your previous messages as spam.
* The email address has been blocked as suspicious.

#### What can you do about it?

* If the inactive email address is one of several you want to send the message to, remove it from the mailing list and send the message to the remaining recipients.
* If you believe that none of the above situations occurred and the address was unfairly marked as inactive, you can try to resend the message.
* If the recipient contacts you through another channel, ask them to update their email address.

The appearance of this message is not due to an error on Responso's side, and our support team cannot assist you in resolving this specific issue.
