Email glossary
the words we actually use.
Short definitions for finder, verify, and jobs — so a report does not read like a mystery.
Catch-all
The domain accepts mail for any local-part. Verify cannot prove the person exists; treat as risky.
MX
Mail exchanger DNS records. No MX usually means we will not send or mark as deliverable.
SMTP check
A handshake against the mail server to see if the mailbox can receive. Not a guarantee of a human inbox.
Harvest
Fetching public /about, /team, /contact pages and indexed snippets for mailto and names.
Expand job
Background work after the first finder/search response: more CSE, crawl, or people rows.
Credit
Workspace unit for finder, verify, enrich, and extract. Plan and remaining balance are on Home.
Identity
A sending mailbox you connect (OAuth or SMTP) for outreach and warm-up.
Catch vs unknown
Unknown means the probe did not classify; catch-all means the domain accepts broadly.
