Protect Domain Reputation

Unlike others, you won't be charged for unknown results.

We spot catch-all mailboxes where others fail.

Use API, upload CSV or one-shot verification.
We trim spaces, convert domains to lowercase and punycode, and reject malformed addresses, like missing @ symbols or invalid TLDs and other frequent mistakes.
Our system compares domains against popular providers (like gmail.com and outlook.com) to spot and fix subtle errors.
We block throwaway emails
We check addresses against an always-updated disposable email list and flag suspicious domains, like newly registered or “temp mail” providers.
Our system looks up mail server (MX) records and tests connections to ensure the domain can accept messages.
We identify domains that accept any email address (even fake ones), so you can avoid risky sends and hard bounces.
