What it returns

Every field the extractor writes to its dataset, with its type, a written description and an example value.

Field	Type	What it holds	Example
email	stringnull	Email address, as published by the source.	hello@example.com
status	stringnull	Outcome recorded for this row.	ok
confidence	stringnull	How confident the Actor is in this result, from 0 to 1. Not a probability of correctness.	<confidence>
reason	stringnull	Why this row carries its status.	row retrieved successfully
domain	stringnull	Domain name, without the scheme.	example.com
isDisposable	booleannull	Whether the domain is a known disposable-address provider.	true
isRoleAccount	booleannull	Whether the address is a shared role mailbox such as info@ or sales@.	true
mailServer	stringnull	Mail server the domain uses.	<mailServer>
suggestedCorrection	stringnull	Likely intended address, when the one given looks mistyped.	<suggestedCorrection>
score	integernull	Score on the Actor's own scale. The scale is stated in the field's own band.	82
scoreBand	stringnull	Band the score falls into, in words.	<scoreBand>
mailProvider	stringnull	Mail provider hosting the domain.	<mailProvider>
isCatchAll	booleannull	Whether the domain accepts mail for any address, which makes single-address verification unreliable.	true
catchAllStatus	stringnull	Whether the domain accepts mail for any address.	<catchAllStatus>
smtpStatus	stringnull	Outcome of the SMTP conversation.	<smtpStatus>
smtpCode	integernull	SMTP response code returned by the server.	0

03 — input

What you give it

Input	Type	Description
emails	arrayrequired	One address per line, or paste a comma-separated list.
onlyStatus	stringoptional	Filter the output. Choose 'valid' to get a clean sending list.
maxItems	integeroptional	Hard limit, strictly enforced. You will never be charged for more.
concurrency	integeroptional	Higher is faster. Lower if your DNS resolver rate-limits.
catchAllCheck	booleanoptional	Probe each domain once to see whether it accepts mail for ANY address. On a catch-all domain a 'valid' verdict proves nothing — this is the single biggest cause of bounced 'verified' lists. Needs outbound port 25, which most cloud hosts block; the result says so plainly when blocked.
smtpCheck	booleanoptional	Ask the mail server directly whether the recipient exists (RCPT TO, no mail sent). The only direct evidence available — but port 25 is blocked on most cloud hosts, and some providers answer misleadingly. Off by default.
