Hey Product Hunt 👋
I built HeroBounce because I kept running into the same problem in my data work - you'd verify a list, get 30-40% marked as "unknown" on catch-all domains, and have no idea what to do with them. Skip them and lose good leads. Send to them and kill your sender reputation. Every tool I tried just gave up at that point.
So I built something that doesn't give up.
HeroBounce uses a 6-layer validation engine - each layer has its own sub-steps, 40+ checks in total - that actually attempts to resolve catch-all domains using pattern analysis, domain intelligence, and SERP data - resolving over 50% of what other tools return as unknown. It's not magic, it's just not giving up as early as everyone else does.
It's early - we launched a few months ago, have a small but growing user base, and I'm still the one answering support emails. The free plan gives you 100 verifications a month with no card required, which is a good way to see if it works for your use case before committing.
Would love feedback from this community - especially if you've hit the catch-all problem before and found a workaround I haven't thought of yet.
