COMMON QUESTIONS
Short answers before you start.
Does verification send an email?
No. Verification evaluates address, domain, and mailbox signals without sending a message.
What does “unknown” mean?
A definitive answer could not be reached. Retry later or route the address for review.
Can I verify lists and new signups?
Yes. The same classification model supports one-off checks, bulk files, and real-time requests.
