The reply guy strategy on X, without the cringe
Updated
The reply guy strategy means growing by replying to other people's posts instead of waiting for your own to spread. It can work for small accounts because readers of a thread already care about the topic. To keep it useful, reply only where you can add something, and do it by hand on a small number of posts each day.
"Reply guy" started as an insult for someone who shows up uninvited under every post. So the goal is to be the opposite: a person whose name readers are glad to see.
Why replies help, and what they don't do
Replies mostly reach the people in that thread. A filter in X's feed code removes replies from accounts a viewer doesn't follow, under the default settings. So don't expect a reply to spread through strangers' For You feeds.
Your position in the thread also matters. X's conversations page says reply ranking considers whether the original author replied, whether the reader follows you, and whether you have a subscription. You can't control much of that, but you can write something the author wants to answer. Our guide on writing good replies has examples, and we cover the subscription part in is X Premium worth it.
Who to reply to
These are rules of thumb from us, not limits set by X.
- Accounts somewhat larger than yours. Their threads have readers, and your reply has a chance of being seen. On huge accounts, a new reply can get buried fast.
- People your future followers read. A big account outside your field won't send you the right people.
- Authors who reply back. Look through a few of their recent threads before adding them to your list.
- Fresh posts. Early replies have less to compete with, and the author is more likely to still be around.
Keep 20 to 30 of these accounts in a private List, and check it each morning.
Find posts with search
Lists show you people you already know. Search finds questions from people you don't.
X's advanced search page covers words, people, places and dates. You can also type operators directly into the search box. X's help page doesn't list all of them, so they could change. We ran min_faves, min_replies, since:, lang:, -filter:replies and -filter:links on x.com on November 3, 2026, and they returned results. We checked the results for likes, replies and dates, but not every post for links.
Replace the topics with your own:
| To find | Search for |
|---|---|
| Questions in your field | "landing page" "what should I" lang:en -filter:replies |
| Posts with some attention | "cold email" min_faves:5 lang:en -filter:replies |
| Conversations already going | pricing saas min_replies:3 lang:en -filter:replies |
| Discussion, not promotion | "onboarding" min_faves:5 -filter:links -filter:replies |
Choose the Latest tab to see fresh posts. If you don't want to remember the syntax, our X advanced search builder writes these for you and also works on a phone.
How many replies to write
We'd start with three to five good replies a day. There's no proven number. It's just about what one person can do well in 15 minutes.
The hard limit isn't your concern. X's limits page lists 200 replies a day for unverified accounts, but you'd run out of useful things to say long before that. If you notice yourself writing replies that could fit under any post, stop for the day.
What to write
Add one thing the post didn't have:
- a number from your own work
- a counterexample
- a question only someone in that field would ask
- the next step the author left out
Here's an invented example. The post says, "We cut our free trial from 14 days to 7."
- Cringe: "Great insight! Thanks for sharing 🙌"
- Useful: "Did activation move, or just the date people churned? When we tried this, signups held steady, but setup-heavy customers dropped because they needed a second week."
Only write the second kind if it really happened to you. Otherwise ask the question and leave the story out. The reply generator can suggest angles when you're stuck.
How to keep it from looking like spam
- Don't reply to the same person all day. Space it out, and skip posts where you have nothing to add.
- Don't plug your product. Let people find it through your profile, and make sure your bio tells them what they'll get.
- Don't automate it. X's developer guidelines list auto-replies to random users as prohibited, and they say AI-generated replies need prior approval before deployment. That's aimed at apps using X's API, but it's a good guide to what X considers spam.
- Don't join reply pods. X's authenticity policy covers coordinating to inflate engagement.
- Accept it when someone isn't interested. If an author ignores or hides your replies, move on.
How to tell if it's working
Check weekly, since small accounts swing a lot from day to day:
- How many authors replied to you?
- Which replies led to a follow, when you can tell?
- What's your net follower change for the week?
If authors answer you but nobody follows, your profile may be the problem. If nobody answers, try different people, or look closer at what you're adding. Give it a couple of months before you judge it.
Repli builds this into your morning. It finds fresh posts on your topics and drafts replies in your voice, and you decide what to post on X yourself. See the demo for a sample on an invented account.
