Auto-retweet your own X post

Auto retweet tells PostFast to retweet your own X post some time after it goes out, useful for giving a post a second wave of exposure without having to remember to retweet it yourself.

This is different from the Tweet URL option, which retweets someone else's tweet. See Retweet a tweet on X for that one.

How it works

When you enable Auto retweet and pick a delay, PostFast schedules a retweet of your own published post to run after that delay. You can add more than one schedule (for example, one retweet at 6h and another at 1d) to get multiple waves off a single post.

Enable Auto retweet

1. In the composer, open Post settings → Platform settings and select your X account.
2. Turn on the Auto retweet toggle.
3. Pick one of the preset delays (6h, 12h, 1d, or 7d) or click + Custom time to enter your own.
4. To add more waves, pick another delay; each chip you select becomes an additional retweet schedule for this post.
5. Schedule or post as normal.

Once the original post publishes successfully, PostFast handles the retweets in the background.

What happens on each schedule

For each delay you added, PostFast:

1. Waits until the delay elapses from the original post time.
2. Retweets your post on X.
3. 12 hours later, removes the retweet.

If the original post fails to publish, any auto-retweets attached to it are cancelled, there's nothing for PostFast to retweet.

Tips on picking a delay

• 6h works well for same-day reach in a different timezone.
• 1d is handy for catching followers who missed the first wave.
• 7d is good for evergreen posts you want to resurface after a week.
• Use multiple delays on one post if you want several waves.
