Pre-filter rows
Apply the workflow to up to 500 rows at a time before a campaign or CRM import.
For teams cleaning large email lists
Pre-filter risky email rows without SMTP probing.
Clean a bounded list before it reaches your sending workflow. The kit uses public DNS and address-pattern signals, keeps an explicit unknown outcome, and does not pretend to prove mailbox deliverability.

Built for list cleanup and triage, not for bypassing mailbox providers or sending mail.
Keep unknown explicit
Catch-all domains, stale MX records, and ambiguous patterns stay unknown instead of becoming false certainty.
Use the Actor if needed
For metered automation, the public Apify Actor is available separately at pay-per-event pricing.
Scope
A safer pre-filter, not a deliverability guarantee.
- No SMTP probing, mailbox login, email sending, or inbox discovery.
- Public DNS and address-pattern signals only; ambiguous results remain unknown.
- No guarantee that an address accepts mail or that a campaign will deliver.
- Self-service kit; individual implementation and list handling are not included.
