Nobody posts their reply rates by channel. Here are mine.

Everyone loves to declare a channel dead. Cold email's dead. LinkedIn's dead. Nobody posts real numbers, so it stays a vibes argument.

Here are mine. Same product, same offer — just sent in different places. Across 27,178 conversations:

Reddit — 20.6%
LinkedIn — ~14%
X — ~9%
YouTube — ~6%
Cold email — ~1%

The top channel replies twenty times more than the one most people pour budget into. One reason: on the top four, the person already typed the problem out loud in public. Cold email is you guessing they have it and interrupting on a random Tuesday.

Here's the free part — how I'd mine each one by hand, today, no tool:

Reddit — search your buyer's pain phrases, sort by New, stick to niche subs. the "anyone know a tool for X" posts with 2 comments convert better than the 200-comment ones.

LinkedIn — same phrases in the search bar, set to Latest. comment in public first, DM second. the comment is what makes the DM land.

X — save 3-4 phrase searches, reply in the open. on X the reply is the funnel, not the DM.

YouTube — read the comments on tutorials next to your product. people literally type the feature they wish existed.

Notice the pattern: you're not blasting anyone. You're finding the one person who described your product in their own words and replying like a human. That's the whole reason the top of that list beats the bottom.

I got tired of running all four by hand, so LeadSynth watches them for me — catches the person the moment they post, drafts in my voice, books the call. First leads are free, no card: https://www.leadsynthai.app — but the phrase-search trick costs nothing and works on its own.

Real question for the room: what's your highest-reply channel right now, and your worst? Wondering if the cold-email gap holds across niches.
