Scheduled

We will add a new substatus in your validation results for email addresses with "valid" and "catch-all" statuses: ai_agent_mailbox

If you use ZB Sub Status values in API workflows, we recommend reviewing any logic that depends on specific substatus values to ensure it accounts for these new additions.

No other changes are required.
