A: At this time we don't have the ability to broadcast through Whatsapp because Chat API (Our WhatsApp Integration provider) does not support broadcasts.

We will be integrating with WhatsApp Business API through Twilio soon, which will allow you to do template message (WhatsApp version of broadcasts)

Unfortunately, we cannot allow unlimited contacts. We are a business and do need to keep our servers running for people like you. It would become very difficult for us if we had unlimited contacts.
