You can raise a support ticket to have the rules behind bounce mail management adjusted according to your requirements.
As per default, this is how bounces would be treated:
To turn a subscriber status to Held, mail to that address has to
have bounced 3+ times with at least 15 days between first bounce and
most recent bounce.
The “3 times” and the “15 days” setting can both be modified. Either to less or more restrictive settings.
For each type of bounce you have two options:
- Apply the “X over Y days” logic
- “One and done” - one single bounce turns an address to “Held” status.
The last one is what you need.
