MailCull
Clean your email list for $19, not $300
ZeroBounce and NeverBounce charge $300+ and hide everything behind a "valid" label. MailCull does the same job for $19 a month flat, shows you why each email is safe, risky, or dead, and its AI analyst gives you a plain-English read on the close calls. Stop the bounces, protect your sender reputation.

Hi everyone, maker here. Quick story: a friend asked me to help clean a cold email list that kept bouncing. The big tools wanted $300+ to do it, and I figured, why pay that much? It took me a few months to polish, but I built MailCull instead. It does the same job for $9 a month flat. You upload your list and it tells you which addresses are safe to send to and which will bounce, so you can clean it before a campaign and protect your sender reputation. For the tricky ones (catch-all and unknown), an AI analyst gives you a plain-English read so you know whether to keep them, drop them, or send slow. Free to try, no card. A REST API and an MCP server are included too, if you want to verify from your own app or an AI agent. Genuinely want your feedback: for anyone here sending cold email or running newsletters, how do you handle catch-all and unknown addresses today? Do you remove them, segment them, or just send to them slowly? That's the part I keep going back and forth on.
