Rasayel limits

There is a limit of 10,000 users per campaign. We will prevent you from sending a campaign to more than this number of users.

WhatsApp limits

WhatsApp has messaging limits for each tier your number is on. Business phone numbers are initially limited to 250 business-initiated conversations in a 24-hour moving period, but this limit can be increased to an unlimited number of messages. You can read more about this here. Rasayel, for its part, attempts to work around this by retrying messages that hit these limits 12 hours after the limits are hit.

Impact on the number rating

When sending mass messages like this, you need to make sure of the following points:
  1. The numbers you are sending to are actually valid WhatsApp accounts. If you send messages to invalid WhatsApp accounts (numbers that aren’t on WhatsApp), Meta views this unfavorably and can reduce your number rating
  2. If your contacts do not opt in or report your messages as spam, Meta will reduce your number rating.
