Domain Reputation Checker by Truelist - Is your domain blacklisted? Find out in seconds, free

Hey Product Hunt 👋 Corey again, co-founder of Truelist. Here's the thing about domain reputation: it decays silently. Blacklists don't notify you when they list you. A stale SPF include breaks your authentication. Your open rates slide and everyone blames the copy. We built this checker because "why did deliverability drop?" is the most common question we get — and the answer is usually visible in 10 seconds if you know where to look. Enter a domain, and it checks blacklist status across the major lists, parses your SPF and DMARC (and actually grades the configuration, not just "record found"), reviews your mail infrastructure, and hands you a letter grade with specific fixes, prioritized. Fun story from prepping this launch: we ran our own domain through it and got a C — it caught a missing SPF record on truelist.io that we'd somehow never noticed. We fixed it because our own tool told us to. That's about the strongest endorsement I can give it. It's free, no signup. ~800 people a month already find it through Google; today it gets a proper introduction. What did your domain score?
