We would want to sent approx. 40K messages per month about 1300 messages per day - pre-scheduled. 1. Is this possible? Also, I read in other comments that whatsapp accounts may get blocked sending out bulk messages. 2. What are the reasons this happens? 3. What would you suggest to avoid this? 4. Do I understand it correctly that when a number is already added as a contact, it avoids getting blocked? 5. Is it possible to only sent out messages and blocked to receive any? 6. And are there any additional costs to take into account for the usercase as explained above? Thank you beforehand!
