Emailable

built for real-time, in-form verification

if you're verifying inline at the point of signup, its latency advantage matters more than the small accuracy gap behind the leaders.

emailable is built around real-time single-address checks rather than bulk cleaning, and the product is shaped accordingly. for a signup form where the user is waiting on the response, latency is the whole ballgame — a verifier that takes two seconds gets ripped out regardless of how accurate it is.

the javascript widget for inline form validation is the best implemented of the bunch and handles the awkward cases (user still typing, corporate catch-all, temporary failure) without blocking submission.

the description above is ours, condensed from the ranking. pricing moves — check it on the vendor's own page before you rely on it.

we researched this category against vendors' own pricing pages and licence files. that is where this line comes from — not from the vendor, and not from anything they paid for.
