Posts per day
- 200 posts per calendar day (from midnight, your time), on every plan. One post to one group counts as one.
- A run that would go past 200 shows a "Safety limit check" first. If you continue, it posts until it reaches 200 and stops. With no answer in 60 seconds, it cancels.
- A scheduled run that would go past 200 is skipped and shown as missed.
- The same post is not sent to the same group twice within 20 hours.
- Our guidance, not a guarantee: 50 to 100 posts a day for accounts older than a year, about 40 for accounts 6 to 12 months old, fewer for newer accounts. No tool can promise Facebook will never limit an account.
Pacing between posts
At the default pacing, 50 groups take about three to four hours. The run continues on its own while Chrome is open.
- Default: a random pause of about 3 to 6 minutes after every 1 to 3 posts.
- The pause grows with the posts already sent that day: 1.5 times longer from 10 posts, 2.5 times from 30, 4 times from 60 and 6 times from 100.
- Runs to more than 60 groups add a few seconds (about 4 to 7) before every post.
- Your own setting: a wait of 1 to 60 minutes after every 1 to 50 posts, randomized if you choose.
