If you are deciding what to send to a paid verifier, a useful first pass is to separate four things: syntax/typo, public DNS/MX, disposable signals, and role addresses. Ambiguous rows stay unknown; this is not SMTP probing, mailbox login, sending, or a deliverability guarantee. It is for buyer-owned lists and is bounded to 500 rows per run. I built the starter kit and maker notes here: https://whop.com/checkout/plan_Q...
A privacy-bounded first-pass filter for buyer-provided email lists. Checks syntax, MX, disposable and role-address signals without SMTP probing or mailbox existence checks. Includes the public Apify Actor link and input/output guidance. 500-address limit per run. No guarantee of deliverability, mailbox existence, or inbox placement. Buyer supplies the list and remains responsible for lawful use and permissions.
