ABOUT
Verification with transparent confidence.
Russell Verify checks whether email addresses exist and finds business email addresses. It never sends emails to the addresses it checks and never asks for their mailbox passwords. Russell Verify accounts use passwords that are stored only as secure one-way hashes, never in plain text; see the Privacy Policy for how account data is handled.
What the service does
For each address, Russell Verify checks the domain's DNS and mail servers and asks the receiving mail server whether it would accept mail for the address. The conversation stops before any message is sent: no email is ever delivered to the address. For Catch-all and Unknown results it can also look for the exact address on the company's own public website (Public Evidence).
Four honest outcomes
Valid and Invalid require definitive evidence. Catch-all requires a confirmed control test. Unknown protects you from false certainty when mailbox evidence is unavailable. No service can promise perfect mailbox verification.
What we never do
We never send emails to the addresses we check, never ask for their mailbox passwords, and never log in to any mailbox or website. The only emails Russell Verify sends are account emails (verification, password reset and security notices) to the account holder. Account passwords are stored only as secure one-way hashes, never in plain text. See the Privacy Policy for what is stored and for how long.
