post/email-preflight/v1/check_links2 credits

Resolve every link in the email through url-resolver (SSRF-guarded): final URL, redirect chain, status, final domain. Bot-403/429 = `unverifiable` (honest — not marked broken). Inner-calls url-resolver per link.

Working example

Parameters

The full HTML of the email you are about to send (paste the source). Parsed read-only in a no-network, no-script sandbox.

base_urloptional

Optional base URL: relative links/images in the HTML are resolved against it before checking.
