Vetto
Claude connectorCommunityCheck signup emails for disposable and dead domains and typos, spot Gmail aliases of the same inbox, and get setup steps to block fake sign…
Vetto helps developers and SaaS founders deal with fake and broken signups. Ask Claude whether an email is real, which of your recent signup domains are throwaway, or how to block them on your stack.
Tools (all read-only):
- check_email: checks one address for invalid syntax, disposable/throwaway domains, domains that cannot receive mail (no working MX), likely typos with a suggested fix (jane@gmial.com -> jane@gmail.com), role addresses, and privacy relays such as Apple Hide My Email, which are allowed because they reach a real inbox.
- check_domains: audits up to 50 email domains at once and says which are disposable or cannot receive mail.
- same_inbox: tells whether two addresses reach the same inbox after Gmail dot, +tag and googlemail.com normalisation, to spot repeat free-trial signups.
- how_to_block: returns setup steps and a guide for Next.js, Supabase, Clerk, Better Auth, Auth.js, Firebase, Laravel, Django or any HTML form.
No account or API key. Email addresses are analysed in memory and not stored.
