Undeliverable

The contact’s Internet Service Provider didn’t respond. We’ll keep trying to deliver the email for up to three days. If there’s still no response, we’ll mark it Undeliverable.

Suspended

Email addresses that bounce as Non-Existent multiple times are marked Suspended and we are no longer attempting to send email to them. If you think this is a valid email address, click the menu to the right and choose Unsuspend.

Other

The response from the contact’s Internet Service Provider was not one of the standard codes, so we marked the bounce as Other.

Blocked

The contact’s Internet Service Provider decided not to deliver the email. This is usually due to reputation or content (images, links, text, etc.), or a filter on the recipient’s end.

Non-existent

The contact’s Internet Service Provider didn’t recognize the email address.
