Verifies email address deliverability by connecting to the recipient's mail server and running an SMTP check without sending any mail. Resolves MX records, performs a RCPT TO handshake, and detects catch-all domains. Accepts single addresses, multiple addresses, or CSV files.
Checks whether an address is deliverable without sending a message, avoiding bounce penalties, credit consumption, or domain reputation impact.
