Email Validation
LiveCatch throwaway inboxes before they cost you.
Validates the address really exists and classifies what kind it is. Disposable domains are the single strongest predictor of free-trial abuse, and the list is refreshed continuously rather than shipped static.
What it detects
- Disposable and temporary providers
- Live MX and mailbox verification
- Role accounts (info@, admin@, support@)
- Homograph and lookalike domains
- Typo correction (did-you-mean)
- Catch-all domain detection
When to use it
At signup to stop trial abuse, and before sending to protect your sending reputation.
Questions
How do you keep up with new disposable providers?
New throwaway services appear constantly, so a static list decays fast. Detection combines a continuously refreshed provider list with structural signals — domain age, MX configuration, and whether the domain behaves like a real mail host or a disposable front end.
What is a homograph email?
An address whose domain reads as a legitimate one but is not — Cyrillic characters standing in for Latin, or fullwidth spellings that fold onto a real ASCII name. They exist to survive a human glance, which is exactly why a machine should catch them.
Is mailbox verification safe to run at signup?
Yes. It is an SMTP-level check that the address would accept mail — no message is sent, and nothing lands in the user's inbox. Some large providers deliberately refuse to answer, in which case the result is reported as unknown rather than guessed.
