An official bulk WhatsApp sender sends high-volume WhatsApp messages through the Meta WhatsApp Business Platform (Cloud API) using pre-approved templates to contacts who opted in, with delivery, read and reply analytics on every campaign.

What official bulk sending costs
Meta bills per template message by category (marketing, utility, authentication). Your BSP adds a platform fee. WappBlaster charges a flat ₹7999 / $200 per year with 0% markup on Meta, so your variable cost is transparent Meta rate card only.
