Email Validator checks whether an email address is real and deliverable — or a disposable, fake, or role-based address that will never convert. It returns a confidence score so you can make data-driven decisions about which addresses to keep.
Each check verifies format, looks up DNS and MX records to confirm the domain can receive mail, detects disposable and temporary providers, flags role-based addresses like info@ and support@, and surfaces any blacklist signals. Bulk mode handles up to 20 addresses in a single call with summary counts so you can clean a list quickly.
What you can do
- validate_email — validate a single address with format check, DNS/MX verification, disposable detection, confidence score, and risk signals
- bulk_validate — validate up to 20 addresses at once with a summary of invalid and disposable counts
- verify_email — run direct mailbox verification through a connected commercial source with status, score, checks, and source metadata
Who it's for
Marketers cleaning email lists, developers validating signup forms, sales teams qualifying CRM data, and anyone who needs to stop bounces before they hurt deliverability.
How to use it
- For a single address, call validate_email — a confidence score below 50 means likely undeliverable.
- For list cleaning, call bulk_validate with an array of up to 20 addresses.
- Filter out any results where disposable is true or confidence is below 50 to keep only high-quality addresses.
Getting started
Call validate_email with any email address. Connect the optional commercial verification source when you need direct mailbox checks.
