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.
Official vs unofficial “bulk senders”
| Trait | Official Meta API sender | Unofficial blaster |
|---|---|---|
| Channel | WhatsApp Business Platform | WhatsApp Web / modified APK |
| Templates | Meta-approved IDs | Free-text spam |
| Opt-in | Verifiable consent log | Scraped numbers |
| Scale | Messaging tiers + quality rating | Sudden number ban |
| Analytics | Delivered / read / replied / clicked | “Sent” counter only |
Five components every official bulk sender needs
- WhatsApp Business Account (WABA) tied to your legal business entity.
- Approved templates in marketing, utility or authentication categories.
- Opt-in capture — web forms, checkout, QR, or IVR with timestamp storage.
- Campaign console — segments, schedules, variables, suppress lists.
- Reply handling — shared inbox and optional AI chatbot on inbound messages.
Typical first-month workflow
- Week 1: Business verification, phone number onboarding, display name approval.
- Week 2: Submit 3–5 templates; import opted-in contacts with source tags.
- Week 3: Pilot send to 500 contacts; measure read % and opt-out %.
- Week 4: Scale to full list; connect CRM or Shopify webhooks for triggered sends.
What official bulk sending costs
Meta bills per conversation category (marketing, utility, authentication, service). Your BSP adds a platform fee. WappBlaster charges a flat ₹7,999 / $200 per year with 0% markup on Meta — so your variable cost is transparent Meta rate card only.
