Spaces

Facebook Messenger limits for businesses

Messenger is one of the stricter channels for automation. Published guidance recommends far lower numbers than for WhatsApp or LinkedIn, and a gradual start. Here are the numbers, and what Spaces enforces.

What the guidance recommends

  • Between 10 and 50 messages a day, and never more than 50.
  • Start at about 15 a day and add about 5 a week.
  • Message people you share mutual connections with.

Messenger only lets you reach someone who has not written to you inside its messaging window, so it works best for answering people who message your business. That is what Spaces is built for.
