Bulk WhatsApp broadcasts beyond the 256-contact limit
The WhatsApp Business app caps broadcast lists at 256 contacts who must save your number first. Sandeshly sends bulk WhatsApp campaigns to thousands of opted-in contacts — personalised per recipient, scheduled, throttled inside Meta's limits, and tracked message by message.

Live delivery tracking
Sent, delivered, read, replied — per recipient, in real time, with failure reasons and CSV export.
Replies go to your team
Every response lands in the shared inbox, linked to the campaign that triggered it.
Broadcast to thousands — the official way
A bulk WhatsApp campaign on Sandeshly uses Meta-approved message templates sent through the official WhatsApp Business Cloud API from your own verified number. There's no 256-contact broadcast list, no requirement that recipients save your number, and no grey-route tooling that could get you banned.
How a bulk campaign works
Upload your opted-in list (or pick an audience), choose an approved template, map your variables, preview, and send or schedule. Sandeshly throttles the send to stay inside your number's messaging tier, retries transient failures, and streams delivery and read status back to your dashboard live.
Why unofficial bulk senders get numbers banned
Bulk-sender browser extensions and modded apps blast messages through the personal WhatsApp app against its terms of service. Meta detects the pattern — volume, no opt-in, spam reports — and bans the number, often permanently. The official API with opt-in lists and approved templates is the only durable way to send at scale.
Bulk broadcast — frequently asked questions
How many WhatsApp messages can I send in bulk? +
Thousands per day. Meta assigns each number a messaging tier (1K, 10K, 100K, unlimited business-initiated conversations per 24 hours) that grows with volume and quality. Sandeshly paces your sends inside your tier automatically.
Will bulk messaging get my number banned? +
Not on the official API with opted-in contacts and approved templates — that's the sanctioned way to send at scale. Bans happen to unofficial bulk-sender tools that automate the personal app. Sandeshly is built entirely on the official Meta Cloud API.
What does a bulk WhatsApp campaign cost? +
Your platform plan (from ₹999/month) plus Meta's per-conversation fees, which depend on category and country. Sandeshly passes Meta's fees through at actual rates — zero markup — and shows the estimated cost before you send.
Can I personalise bulk messages? +
Yes — every template variable can be filled per recipient from your CSV or contact fields, so each of the thousands of messages reads like it was written for that person.
