Hard bounces

See also: Bounce management in Ometria

Hard bounces are emails that bounce and the recipient is identified as invalid. Retrying typically does not work. 

Common reasons for hard bounces include:

• a typo in the email address (e.g. me@gmial.com),
• a deactivated email address (i.e. it no longer exists).

Hard bounces are permanent, and suggest that the email address will never be successfully delivered to, so these contacts are added to the suppression list and emails will not be sent to those addresses again.
