Vetto

One script tag on your signup form. Vetto turns jane@gmial.com into a one-click "Did you mean jane@gmail.com?" fix, blocks disposable and dead-domain emails, and flags Gmail alias farms, datacenter/VPN signups and bot bursts used for free-trial abuse. Privacy relays like Apple Hide My Email are allowed, and if Vetto doesn't answer within 800 ms your form submits as usual.

Works on any HTML form: Next.js, Supabase, Webflow, Framer, WordPress. Free on 1 site (1,000 checks/month). Founding Lifetime: $69 once for the first 100 buyers, until Nov 27.
