ZeroBounceLearn more about email validation
Ask your agent to interpret validation evidence in the context of the action you plan to take. A useful result separates deliverable, risky, unknown and policy-sensitive cases instead of forcing every address into yes or no.
What does an email validation API actually check?
Validation can assess syntax, domain and mail-server signals, mailbox availability and risk indicators such as disposable or catch-all domains. The exact evidence varies, so ask your agent to explain what the returned status supports and what remains uncertain.
Do not turn unknown into invalid
Catch-all, protected or temporarily unreachable domains may not support a definitive mailbox result. Keep these separate from clearly invalid addresses and decide whether the planned use justifies further review.
Validate close to the time of use
Mailbox and domain states change. For material outreach or account workflows, ask the agent to verify the final deduplicated list shortly before use and preserve the validation time.
Example prompt
This example asks for an interpretable result rather than a binary label.
Example prompt to give your agent
Use Scrollport to validate [EMAIL ADDRESS]. Explain the deliverability status, catch-all or disposable signals, and any uncertainty in plain language. Tell me what the result supports for [INTENDED USE], but do not send a message or treat an unknown result as invalid. Show me the price before the paid run.
