Keep Your Lists Clean

The validator performs layered checks to reduce bounces and protect sender reputation.

Checks Performed

• Syntax & RFC — catches typos and invalid characters.
• Domain & MX — confirms the domain exists and accepts mail.
• Mailbox heuristics — optional non‑intrusive SMTP checks where permitted.
• Role/Disposable detection — flags addresses like admin@ or temporary inboxes.

Export clean lists and suppress risky addresses to improve deliverability.
