What Are Lists on X?
A List on X is a custom timeline that shows posts only from the accounts you add to it. You can make Lists public or private, follow other people's public Lists, and pin your favourites to the top of your home screen.
According to X's Lists help page and Lists troubleshooting page, you can have up to 1,000 Lists, each holding up to 5,000 accounts, and a List name can be up to 25 characters.
Example
A marketer builds three private Lists:
- Customers: 40 accounts of people who use their product.
- Peers: 80 marketers they want to swap ideas with.
- Big accounts: 25 large accounts in their niche where a good reply gets seen.
Each morning they open "Big accounts" first and reply to two or three fresh posts.
Why it matters for growth
- Replies on time. Replies posted early on a popular post are more likely to be seen. A List of key accounts helps you get there first.
- A calmer feed. A List cuts out the noise of the For You feed so you can focus on relationships.
- Private Lists stay private. Anyone can view a public List and its members, so keep competitor or prospect Lists private.
