| - | ====== Bounces ====== | ||
| - | An email bounce occurs when we attempt to send an email, but the destination mailserver does not accept it. Depending on the type of bounce message we receive, we may log a bounce against the contact. If a contact receives three consecutive bounces, from three separate emails, we will then automatically mark them as a [[bad-address|bad address]]. | ||
| - | |||
| - | In some cases destination mailservers respond with very specific bounce messages, such as "user unknown", which are considered to be severe enough to immediately triggered a bad address flag against the contact. | ||
| - | |||
| - | We do this to help protect your sending reputation. For example, email providers may identify your sending to known bad addresses as spam-like behaviour; to them it closely resembles how spammers operate. For example, spammers might write a script to guess email addresses @yahoo.com. To an email provider, a sender hitting lots of these non-existent email addresses looks very suspicious. | ||
