Limits to sending messages on Facebook

This is about using messages on Facebook. For help with the Messenger app or, visit the Messenger Help Center.
Facebook has limits in place to prevent behavior that others may find annoying or abusive. These limits restrict the rate at which you can use certain features on the site. If you were warned for sending messages too quickly, you'll need to stop this activity temporarily to avoid being blocked from sending messages.
Please keep the following in mind:
  • Make sure to use your authentic name and picture to help the people you're messaging recognize you.
  • Facebook prides itself in protecting the people who use it from spam, and doesn't allow messages promoting or advertising a product, service or opportunity.
  • Unsolicited messages of any kind aren't allowed.
