## About

## What it does
Email Deliverability Score checks an email address for three common deliverability signals: syntax validity, MX availability, and whether the domain is disposable. Send an `email` string and get back a compact result you can use to decide whether an address is worth storing, sending to, or asking the user to correct.

The response includes the original `email`, a numeric `score` from 0 to 3, the corresponding `level` (`low`, `medium`, or `high`), and `max` for the scale ceiling. It also returns boolean flags for `valid_syntax`, `has_mx`, and `disposable`, so you can inspect the specific reasons behind the score instead of relying on a single label.

Use Email Deliverability Score in signup forms, lead capture flows, CRM hygiene jobs, and onboarding pipelines where early email checks reduce bounce risk and bad data. The output is small and direct, which makes it easy to gate account creation, flag suspicious addresses for review, or route questionable emails into a confirmation step.

If you only need a fast, structured check of an address before sending mail or creating a user record, this endpoint gives you the key signals without extra parsing.
