  • Tier 1: Send messages to 1K unique Contacts in a rolling 24-hour period.
  • Tier 2:Send messages to 10K unique Contacts in a rolling 24-hour period.
  • Tier 3:Send messages to 100K unique Contacts in a rolling 24-hour period
  • Tier 4:Send messages to unlimited unique Contacts in a rolling 24-hour period

This scale is automatically based on your phone number status, phone number quality rating, and how often you initiate conversations with unique customers.

Increasing Your Limit

Each time you initiate a new conversation with a unique customer Meta “Facebook” will determine if your limit should be increased. This determination is based on the following criteria:

1- your phone number quality rating is Medium or High.

2- in the last 7 days, you have initiated X or more conversations with unique customers.

Examples of Increasing Your Limit

Messaging limit increased from 1K to 10K in 7 days:

You will be able to send 10K per day when you send in the last 7 days > X message.

X = current messaging limit divided by 2

x = 1000/2 = 500

So if you send >500 messages last 7 days you will move to Tier 2 and you can Send messages to 10K unique Contacts in a rolling 24-hour period.

Best practices to improve a high-quality rating

  • Only send messages to users who have opted in to receive messages from your business.
  • Make the messages highly personalized and useful to users. Avoid sending welcome or introductory messages.
  • Be mindful of messaging frequency; avoid sending customers too many messages a day. Be thoughtful of informational messages, optimizing for content and length.
  • Send messages to your clients in their language if you know that.
  • Carefully design multiple templates (OTP – Invoices – Shipment Tracking – Offers) and send the customer the appropriate template that he is waiting for, because there is a customer who wants notification messages and invoices to arrive, but does not wish to receive offers, so he may report the offer and advertisement template, thus negatively affecting the account and the template.
  • Provide the option to unsubscribe through your templates, so that your database is clean and contains only loyal customers.
