Hey Product Hunt I built NetDig after one too many times hitting MXToolbox’s rate limit mid-incident at work. The frustrating thing about DNS and email tools is that the problems they solve are urgent — your email is bouncing, your DNS change isn’t propagating, your SSL cert is misconfigured. The last thing you want is a paywall or a “you’ve used your 5 free lookups today” message. So I built the toolset I actually wanted: ∙ Email header analyzer that traces the full delivery path and shows exactly why an email went to spam ∙ Blacklist checker against 30+ DNSBLs with one-click delist links ∙ DNS Record Builder — select Google Workspace, Microsoft 365, SendGrid, or 25+ other services and get copy-ready records without digging through help docs ∙ SSL chain visualizer that catches missing intermediate certificates (the bug Chrome hides but curl and mobile apps don’t) ∙ DNS propagation checker querying 20+ global resolvers simultaneously Everything free, no account, no rate limits. Would love feedback on what’s missing, what’s broken, and what tools you reach for that aren’t here yet. Happy to answer any questions below​​​​​​​​​​​​​​​​
