I've Been Doing Cold Outreach on X for the Past Few Days. Here's What I've Got

4•timczm•6mo ago
HN like data, here's what I've got:

Accounts scanned: 710 DMs sent: 126 (17.7%) Can’t DM: 584 (82.3%) From those DMs:

Positive replies: 4 (3.2%) Rejected: 1 (0.8%) No response: 121 (96%)

Here’s the process:

. I started by figuring out who my product(which is Snapdemo.io) is for. Then I found some KOLs in that niche and used an API to grab all their followers. That gave me 37k potential leads.

. Next, I used AI to scan bios and guess whether someone might be my Ideal Customer. For each account, I asked AI to tell me:

- Are they ICP? (Yes, No, Not sure) - Why? - What’s their label? (e.g. AI builder, SaaS exec)

. I ran all this through OpenAI’s batch API to save on cost and dev time. Once I had a few thousand ICPs, I skipped the “Not sure” ones since the confirmed ones were enough.

. I made a simple dashboard to track everything, and used a few templates to auto-generate DMs. I also logged which template went to which user, so I could measure performance later.

Without a solid automation tool, and with most users not open to DMs, the whole process took a lot of time.If you’ve done something similar, I’d love to hear your suggestions. And if you’re also a founder, feel free to DM me (X: @timchengb) to exchange ideas.

If no one else does I'll just say thanks for the raw data here.

Mmmmm data!

Thanks for sharing. Have you tried anywhere else like Reddit or LinkedIn? Curious how X measures up.

Also, tried DMing but need to be verified lol
