Free tools for cleaner inbound
Check a suspicious submission, spot fake and disposable emails, and keep your address away from scrapers. No sign-up.
Form spam checker
Paste a message that came through your contact form, the one you almost called back. See whether it's a real lead, a sales pitch, or spam, and why.
Fake email checker
Paste an email address from a form fill or sign-up. See whether it's malformed, disposable, a free or role inbox, or on a domain that can't receive mail.
Disposable email checker
Find out whether an address comes from a temporary inbox like Mailinator, 10 Minute Mail, or Guerrilla Mail, the kind people use to get past a sign-up form.
Free email domains list
Every free email provider domain we know of, from Gmail and Outlook to regional webmail. Search it, or download it as TXT, CSV, or JSON.
Email obfuscator
Turn an email address into code that people see normally but simple scrapers can't read. Runs entirely in your browser: nothing is sent anywhere.
