What is a 'Soft Bounce'?
The Soft Bounce message indicates that we were temporarily unable to deliver the email, but may be again in the future. This could be caused by the recipient's inbox being full, email service being temporarily unavailable etc.
What is a 'Hard Bounce'
A Hard Bounce indicates that we are, and will be unable to deliver emails to this address. The domain may be valid, but the email address is not recognised as existing by the email service provider.
