Twitter Lists: How to Set Up X Lists for Your Niche
A Twitter List, now called an X List, is a timeline you build yourself. You pick the accounts, and the List shows posts from only those accounts, newest first, with no algorithm deciding what you see. Make one from Lists in your profile menu and keep it private if you don’t want people to know they’re on it. Then pin it, so it sits as a tab next to For you and Following on your home timeline. A List of the accounts in your niche is useful in two ways: you see what those accounts post that does well, and you find the posts worth replying to first. It won’t grow your account on its own; it changes what you read and who you answer.
Below: how to set a List up, three Lists worth having, and how to turn what you read there into posts.
Why read your niche from a List instead of For you?
You open X to see what your niche is talking about. Twenty minutes later you’ve read a fight about something else, three viral posts from accounts you don’t follow and an ad. You didn’t learn what works for accounts your size, and you didn’t reply to anyone who matters to your account.
The cost isn’t only the time. When the feed picks what you read, it also picks what you copy. You end up writing like the loudest accounts on X instead of the ones your buyers follow, and those posts land with nobody you wanted to reach.
A List fixes the input. You decide who’s in it, so everything you read there comes from your niche.
How do you make a List on X?
On the web or in the app:
- Open the menu from your profile picture and tap Lists.
- Tap the new List icon.
- Give it a name and, if you want, a description. Tick Make private to keep it to yourself.
- Search for accounts and tap Add next to each one, then Done.
To add someone later, open their profile, tap the more menu (the three dots) and choose Add/remove from Lists.
To keep it one tap away, open Lists and tap the pin icon next to it. A pinned List shows up as its own tab at the top of your home timeline.
X allows up to 1,000 Lists per account, according to its help page on List limits. You’ll need three.
Should your Lists be private or public?
| Private List | Public List | |
|---|---|---|
| Who can see it | Only you | Anyone, and others can follow it |
| Good for | Competitors, accounts you study, reply targets | A curated List you share as a resource |
| What it signals | Nothing | That you rate these accounts |
Keep the working Lists private, because a List of the accounts you study or want to reply to is a research tool, not an announcement. Make a List public only when the List itself is the thing you’re sharing, like “founders building in public on [your topic]”.
Which Lists should you make to grow on X?
1. Your niche: the accounts your buyers already read
Add 20 to 50 accounts that post about your topic and whose followers look like your buyers. Mix sizes on purpose, because each size teaches something different. A big account’s winning post tells you what the whole niche cares about. A small account’s winning post tells you what works without a big audience, which is closer to your situation.
Read it once a day. Look for posts that clearly did better than that account usually does, not posts with the most likes. A 2,000-follower account that normally gets a handful of replies and suddenly gets fifty has found something worth studying.
2. Reply targets: where your replies get seen
Pick 10 to 20 accounts in your niche that post often and answer their replies. Replying early, with something useful, puts your name in front of their audience, because a reply posted while the post is still getting views is read by more of them. Our reply strategy guide covers what makes a reply worth a click on your profile.
Rotate this List every month or so. Accounts change what they post and who answers them, so if an account never answers replies, or its audience isn’t your buyer, swap it out.
3. People you’ve met: the relationships
Add people who replied to you, bought from you or talk with you in DMs. Your Following feed has too many accounts to keep up with. This List makes sure you don’t miss the posts of the people who already know you.
How do you turn a niche List into posts?
Reading the List is half of it. Once a week, write down what the posts that beat their author’s usual numbers had in common:
- Format: a one-liner, a list, a screenshot, a short story, a hot take.
- Topic: the problem it named, the result it showed.
- First line: the exact words that made someone stop.
Then write your own versions from your own work, not theirs. “Here’s what I shipped this week and what broke” in the format that won is a post. Rewriting someone else’s winner with your name on it isn’t. Our guide to finding what works in your niche on X goes deeper on reading those patterns.
Can you use Lists without spending an hour on X every day?
Yes, if you separate reading from posting. Read the niche List for ten minutes, reply from the reply-targets List, and close the app. Write and schedule your posts in one sitting a few times a week instead of posting live.
That’s what Kalen does from inside Claude, ChatGPT, Cursor or Claude Code. You give him your niche, your keywords and up to 10 reference accounts, which can be the core of your niche List. Every day he reads the niche’s top posts and X trends. Every week he measures each reference account’s posts against that account’s own usual post. That way you see what beat the norm, not just what got the most likes. When you ask your AI for posts, Kalen hands it that briefing and your open slots, your AI writes from your facts, and Kalen scores each draft against what’s working in your niche. After you approve the plan in the chat, he schedules and publishes on X.
Starter is $9/month with 100 credits, Pro $29/month with 700, Ultra $49/month with 1,500; a post is 1 credit, 2 with a link or a first reply. Your first plan starts with 7 days free and its full monthly credits; cancel before the trial ends and nothing is charged. See pricing or connect Kalen to your AI.
FAQ
Do people know when you add them to a List?
Private Lists are visible only to you. On a public List, the accounts on it can see they’ve been added, and anyone can view the List. If you don’t want an account to know, use a private List.
Can you see Lists other people made?
You can view and follow public Lists. Open a profile and look for Lists in the profile menu, or search for a topic and check the Lists results. Following a good public List is a quick way to start your niche List; copy the accounts you want into your own private one.
Do Lists help your posts reach more people?
Not directly. A List changes what you read, not how X ranks your posts. It helps indirectly: you reply where your buyers are, and you write from what’s working in your niche. See how the X algorithm works for the ranking side.
Is a List the same as an X Community?
No. A List is a timeline of accounts you choose, and those accounts post as usual. A Community is a group with its own feed that members post into. Use a List to watch your niche and a Community if you want to post to one.
How many accounts should a niche List have?
Enough to show you a few strong posts each day, few enough to read in ten minutes. For most niches that’s 20 to 50 accounts. If you skim past half of it, it’s too long.
