Folderly

Hey Product Hunt :wave: I'm Vlad, Founder of Folderly. We've spent years helping sales teams fix deliverability problems after they've already killed their sender reputation and the most painful cases are always the same: someone bought 20+ sending domains from a reseller, assumed they were isolated, and found out they weren't when reply rates collapsed. We thought we'd put together a simple tool that could help. Folderly Lens exists because that diagnosis used to require either a consultant or painful manual DNS spelunking. Now you paste your domain/IP list, and in seconds you get a per-asset KILL / REHAB / KEEP verdict backed by live SPF, DMARC, DKIM, MX, rDNS, and blacklist checks. No mailbox access, no API keys, no test sends. We built this for outbound agencies and sales teams running multi-domain estates who need an answer they can actually act on. The first full audit is free, and we've already run it on a 90-domain client estate where we found 17 SURBL-listed domains the team had no idea about. Would love your feedback and if you're running cold outbound, drop your estate in and let us know what the scanner surfaces. :pray:
