Yes. Emails you get from GetProspect, in search, the extension, enrichment, exports or the API, passed our verification when last checked. We do not deliver accept-all addresses, and you do not pay for emails we cannot verify. Verification lowers bounce risk but can't guarantee delivery. An older saved address can also carry a small warning mark; see Email verification statuses.
Emails in the database are re-verified regularly. To see when an address was last checked, open the person's profile and hover the envelope icon next to the email: it shows Verified -
You usually do not need to verify these emails again. For emails from other sources, such as your own lists or another tool, use Email verifier. It is also worth re-checking an old list of your own before a campaign, since people change jobs.
