An invalid email occurs when you attempt to send email to an address that is formatted in a manner that does not meet internet email format standards or the email does not exist at the recipient’s mail server. Examples include addresses without the “@” sign or addresses that include certain special characters and/or spaces. This response can come from our own server or the recipient mail server.
A message that is returned to the server that sent it. Bounced emails are either a permanent failure to deliver the email or a temporary failure to deliver the email, based on conditions with the recipient mail server.
Hard Bounces - A hard bounce is an e-mail message that has been returned to the sender because the recipient’s address is invalid. A hard bounce might occur because the domain name doesn’t exist or because the recipient is unknown. If a email is on the bounce list, we will auto drop any future requests to this email address.
Blocked messages (also known as a "soft bounce") will appear under Deliverability Stats under Blocked. A block occurs when an e-mail message gets as far as the recipient’s mail server but is bounced back undelivered before it gets to the intended recipient.
A soft bounce might occur because the recipient’s inbox is full, their mail server is struggling, or if the message content was rejected as spam. Blocks represent temporary problem that can be remedied by either the sender or recipient. Blocked users are not suppressed like those with a hard bounce, future sends to these users will be retried.
Spam Reports are triggered when a customer clicks the spam button or puts your email in their spam folder within their email client such as Yahoo, Outlook or AOL. Spam reports can only be gathered from Internet Service Providers that provide a Feedback loop.
It is important that spam reporter email addresses are permanently removed from your send list even if the customer has previously opted in. Continuing to send to customers that have reported your email as spam can severely affect your deliverability rating.
