Abstract Email Validation
Validate and enrich email addresses
Abstract API email validation checks deliverability, MX records, and disposable-domain flags. Free tier with API key from abstractapi.com.
We probe without your API key. A 401/403 auth wall means the server is up — not a full health pass.
