Reply first, DM second: the X warm-up that gets cold messages opened

In January 2026 X swapped its old recommendation system for a Grok-based model and published it on GitHub. People have been reading it since, and the consistent finding is that replies are the heaviest signal in the ranking. HackerNoon's walk-through puts substantial replies at the top, above reposts with comment, profile clicks and likes.

Take the exact multiplier with a grain of salt. It's one publisher's reading of the code. But the direction is clear, and it matches what founders see: a good reply that the author answers gets seen by their audience, and it gets seen by the author.

When you reply to someone's post, three things happen. They get a notification with your name and face. If the reply is good, they often answer or like it. And some of them click your profile to see who you are.

Now your DM isn't from a stranger. It's from the person who had a sharp take on their launch post yesterday. That's the difference between a message that sits in Requests and one that gets opened.

There's a side effect too. A good reply is public, so other founders in the same thread see it. Some of them click through, some follow you, and a few end up in your DMs before you ever message them. One thoughtful reply can warm up more than one lead.

Everyone on X has met the reply guy. Generic praise under every big post, a link in bio, then a DM pitch. People mute him. Don't be him.

• Add something. A number, a counterpoint, a quick story from your own work. “Great post!” is worth nothing.
• Keep it short. One or two lines beats a paragraph in a reply.
• No links and no pitch in public replies. Ever.
• Reply to their posts, not just the big accounts. The prospect is the author, not the audience.
• Space it out. One or two thoughtful replies over a few days beats five in an hour.

1. 1Day 1: visit their profile, like a recent post, leave one real reply.
2. 2Check that their DMs are open. If not, stop here. Keep replying if they're worth it, but don't force a message.
3. 3Day 2 or later: send a short DM that picks up where the reply left off, or opens with what they're building.
4. 4If quiet: one follow-up with a new angle a few days later.
5. 5If they reply: have a normal conversation. Suggest a call only once there's real interest.

Notice the gap between the reply and the DM. Messaging someone five minutes after your first reply feels like a setup. A day or two later, it feels like a follow-on.

Here's what that follow-on DM can look like when the reply above landed:

It references a real exchange, it doesn't pitch, and it asks a question only he can answer. If he says “me, mostly”, you have a conversation.

And if he never answered your reply at all? That's fine. The reply still did its job: he saw your name. Send the DM anyway, just don't pretend you had a back and forth. Open with what he's building instead.

Every reply and every DM sends people to your profile. That's where they decide if you're worth answering. Clear bio, real photo, a pinned post that shows you know the space, and recent posts that aren't all promotion.

Premium helps here too. PostEverywhere reports Premium accounts get roughly 10x the reach per post, and verified replies tend to rank higher in the thread. If X is a serious channel for you, the subscription usually pays for itself.
