Email verification that returns a graded, calibrated judgement on catch-all domains instead of "unknown".
Addresses to verify. Either plain strings, or objects with email / first_name / last_name / company. Supplying a name column materially improves catch-all accuracy; supplying a company column is what makes the wrong-employer case decidable at all.
Read the rows from an existing dataset instead of the list above.
Column holding the address. Left empty, the usual spellings are detected automatically.
Full name. Left empty, first_name/last_name are detected automatically.
Employer name. Left empty, the usual spellings are detected automatically.
Apify blocks outbound mail ports, so this cannot work on the platform and is off by default. Leaving it off costs you nothing: a catch-all domain is defined by SMTP telling you nothing, and the catch-all scoring was fitted and measured with SMTP disabled. Turn it on only when running this Actor's code yourself somewhere port 25 is open.
Repeated RCPT samples per address to detect servers that answer known recipients at a different speed. Requires SMTP, so it does nothing on Apify; 0 disables it.
Raise it for a cleaner kept set and a lower bounce rate; lower it to keep more.
Raise it to cut more of the list, at the cost of discarding more genuine addresses.
