Bounces fall into two different categories: soft and hard bounces.
Iterable does not remove soft bounces from your user base. Here are the types of Soft Bounces and their definitions:
SoftBounceGeneral, SoftBounceUndetermined MailBlockGeneral
This is treated as a soft bounce because we cannot determine the exact reason for delivery failure. It could be a non-standard error message, or too vague to be useful.
The connection timed out while trying to deliver the message.
The email server cannot deliver your email because the recipient's inbox is full.
The recipient's email server has blocked your email on the basis that the content resembles spam. This mail block is often triggered by something detected in your email content.
SoftBounceSpamDetected or MailBlockSpamDetected
The ISP has detected content from your email that resembles spam. The trigger can be related to your content, IP address or sending domain that has a poor reputation.
This occurs when an email is sent to a misspelled or outdated email address that is no longer in use. By default, Iterable will automatically unsubscribe these users from the sending message channel.
