Email Validator

Validate email syntax, catch disposable and role addresses, and suggest typo fixes - offline and instant.

betaData ValidationAvailable on RapidAPI

RFC-style syntax validation, disposable-domain detection against a bundled curated list, role-address and free-provider flagging, and 'did you mean' typo suggestions for common domain misspellings. Returns a 0-100 quality score with human-readable reasons for every deduction. Fully deterministic and offline - no DNS lookups, no MX queries, no SMTP probing, no live mailbox check. Nothing is stored.
