Bounce (hard and soft)
A message from the receiving server saying it couldn't deliver an email. A hard bounce is permanent (the address doesn't exist); a soft bounce is temporary (a full mailbox, or the server is busy).
How this affects you
A hard bounce adds the address to Vaartix's suppression list for every customer, so no one sends to it again. A soft bounce is recorded as delivery_delayed and never suppressed. Both keep the receiving server's reply, word for word, in the email's timeline and webhooks. A team whose bounce rate goes above 4% over 7 days is paused, so clean your list before sending to it.
