X (Twitter) Limits Explained: Posts, DMs, Follows and More

X caps how much any single account can do in a day: how many posts you can publish, how many direct messages you can send, how many accounts you can follow, even how often you can change your email address. According to X’s help center, the core numbers are 500 DMs per day, 400 follows per day and 4 email changes per hour, plus daily posting limits that X’s own pages describe in more than one way.

Most people never get close to these ceilings. The ones who do are usually heavy repliers, people running giveaways, or anyone automating their account. This guide puts every published limit in one table, is upfront about where X’s documentation contradicts itself, and explains what to do if you hit a wall.

Every published X limit at a glance

All figures come from X’s help center (“About X limits” and the Repost FAQ):

Action	Published limit	Notes
Original posts (unverified accounts)	50 per day	Broken into semi-hourly limits
Replies (unverified accounts)	200 per day	Broken into semi-hourly limits
“Updates”	2,400 per day	Also referenced on the same limits page
Posts incl. reposts	1,000 per day	Mentioned in the Repost FAQ
Direct messages	500 per day
Follows	400 per day	Technical limit
Follows after 5,000	Account-specific	Based on ratios X doesn’t publish
Account email changes	4 per hour

Three rules apply to all of them. Limits count actions from every device and the API, so your phone, the web and any scheduling tool all draw from the same pool. X may temporarily reduce limits during periods of heavy usage. And time-based limits reset once the time period has passed.

The daily post limit: why the numbers don’t agree

This is where most confusion comes from, and it’s worth being honest: X’s own pages don’t give one clean answer.

• The “About X limits” page lists 50 original posts and 200 replies per day for unverified accounts, broken into smaller semi-hourly limits.
• The same page also references a limit of 2,400 updates per day.
• The Repost FAQ says reposts count toward a limit of “1,000 posts per day.”

These figures may apply to different account types or come from different versions of the documentation, but X doesn’t explain how they fit together. So don’t try to reverse-engineer the “real” number. Treat it this way instead:

1. If you’re unverified, assume the 50-post and 200-reply figures apply to you, and that they’re split into half-hour windows.
2. If you’re verified, you may have more room, but X doesn’t publish a separate verified figure on the pages we checked, so don’t plan a strategy that depends on posting hundreds of times a day.
3. Count reposts as posts. The Repost FAQ is explicit that they count toward a daily post limit.

The semi-hourly detail matters more than the daily total. You can be far under 200 replies for the day and still hit a wall if you fire off a burst of replies in a single half hour, which is exactly what happens during live events and reply sprees.

Follow limits and the 5,000 ceiling

Follow limits catch growth-focused accounts more often than any other limit.

• 400 follows per day is the technical maximum for any account.
• After you follow 5,000 accounts, X adds limits specific to your account, based on ratios it doesn’t disclose. In practice, that means your ability to keep following depends on your own follower numbers and behavior, not just a daily count.

X doesn’t publish the ratio, and any exact figure you see quoted elsewhere is a guess. What matters practically: if you’re approaching 5,000 follows and your follower count is much smaller, you’ll likely find further follows blocked. That’s a signal to prune, not to push harder.

A related point: X’s rules on spam and platform manipulation treat aggressive following and follow-unfollow churn as spam behavior. Hitting the follow limit isn’t itself a violation, but the pattern that usually causes it can be.

DM and email limits

• Direct messages: 500 per day. This is plenty for personal use. It becomes relevant for brands answering support DMs at scale or creators doing outreach. If you run customer support through DMs, spread replies across the team’s accounts rather than sending everything from one.
• Email changes: 4 per hour. Rarely an issue, but good to know if you’re troubleshooting account access and trying several addresses in a row.

What happens when you hit a limit

When you reach a limit, X shows an error message that tells you which limit you’ve hit. Nothing else happens to your account: a limit is a speed bump, not a penalty.

What to do:

1. Read the error. It tells you whether it’s posts, follows, DMs or something else.
2. Wait. Time-based limits reset once the period passes. For the semi-hourly post limits, that can be quick; for daily limits, give it the rest of the day.
3. Check your tools. If you didn’t think you posted that much, look at scheduling apps, cross-posting tools or anything else connected to your account through the API. Their actions count too.
4. Don’t try to route around it. Switching devices doesn’t help, because limits cover all devices.

If you’re seeing reach problems rather than error messages, that’s a different issue. See our guide on the X shadowban for what’s actually going on there.

How to stay under X’s limits

A few habits keep almost everyone well clear of the ceilings:

• Pace your posting. Spread posts across the day instead of stacking them. It also tends to work better for reach, since each post gets its own window. Our guide on the best time to post on X helps you pick those windows.
• Batch replies, but not in bursts. Reply sessions of 15–20 minutes spread through the day avoid tripping the semi-hourly limits.
• Use threads for long ideas. One thread is a handful of posts, not a dozen separate ones scattered through your timeline. See how to write a thread on X.
• Don’t follow aggressively. Follow people you actually want to read. Use Lists to track accounts you’re curious about without adding them to your follow count.
• Prune before 5,000. Unfollowing inactive accounts gradually is better than hitting the ratio wall and then mass-unfollowing, which looks like churn.
• Audit connected apps. Remove tools you no longer use; every one with posting access draws from your limits.

Common scenarios and what to do

Scenario	Likely limit	What to do
Live-posting an event, suddenly blocked	Semi-hourly post or reply limit	Slow down and wait for the window to reset
Giveaway replies stop sending	Daily reply limit	Reply to a sample, then post one summary
“Can’t follow more people”	400/day or post-5,000 ratio	Stop for the day; prune inactive follows
Scheduler posts failing	Posts from the API count too	Reduce queued volume
Support DMs failing late in the day	500 DMs/day	Share the load across accounts

Key takeaways

• X publishes limits of 500 DMs/day, 400 follows/day, 4 email changes/hour, and extra follow limits after 5,000 follows.
• Daily post limits are inconsistent across X’s own pages: 50 posts + 200 replies for unverified accounts, 2,400 updates, and 1,000 posts including reposts all appear. Plan for the lowest one that could apply to you.
• Limits include every device and the API, may drop during heavy usage, and reset when the time period ends.
• Hitting a limit isn’t a penalty, but aggressive following is. Pace yourself and you’ll rarely see the error at all. If you’re just starting out, our 30-day plan for growing on X from zero builds these habits in from day one.
