    A finished check: Email Security and Discoverability scored out of 100 side by side, with every component and its points, from MX, SPF, DKIM and DMARC to crawl access, site plumbing, page metadata, structured data and answer-engine readiness.
    Crawl access in detail: AstraVerify requests the page as Googlebot, Bingbot, OAI-SearchBot, PerplexityBot, ClaudeBot and GPTBot and reports what each one actually received, which catches CDN or firewall blocks that robots.txt does not reveal. Each check can be re-run on its own after a fix.
