WhatsApp Broadcast Campaigns: The Complete Guide for 2026

WhatsApp broadcasts are one of the highest-ROI marketing channels available today. With open rates exceeding 90% (compared to 20% for email), a well-executed broadcast campaign can drive serious revenue for your business. Here's everything you need to know.

What Is a WhatsApp Broadcast?

A WhatsApp broadcast sends a single message to multiple recipients simultaneously. Unlike a group message, each recipient gets a private message — they can't see who else received it, and replies come back to you privately. This makes it ideal for promotional campaigns, product launches, and announcements.

WhatsApp Business API vs. Unofficial API

There are two ways to send broadcasts at scale:

• WhatsApp Cloud API (Official): Meta's official API. Requires approved message templates, supports up to 100,000 recipients per campaign, and includes delivery/read receipts. Best for businesses that want reliability and compliance.
• Unofficial API (Baileys): Uses a linked-device connection (QR-code pairing). No template restrictions, no per-message fees, but carries a small risk of number bans if abused. Best for small businesses testing the waters.

Whaterakt supports both — you can switch between them per number from your workspace settings.

Step 1: Build Your Contact List

You can only broadcast to people who have your number saved in their phone contacts (for the unofficial API) or who have opted in (for the official API). Grow your list by:

• Adding a WhatsApp click-to-chat link to your website and social profiles
• Collecting numbers at checkout with explicit consent
• Using WhatsApp Forms to capture leads
• Running WhatsApp Link campaigns (wa.me links with pre-filled messages)

Step 2: Get Your Template Approved (Cloud API)

If you're using the official API, your broadcast message must use a pre-approved template. Submit templates in the WhatsApp Manager under the MARKETING category. Include a clear opt-out option and avoid spammy language. Approval typically takes 24-48 hours.

Step 3: Segment Your Audience

Don't blast your entire list. Segment by:

• Geographic location (city/region)
• Purchase history (repeat customers vs. first-time)
• Engagement level (active chatters vs. dormant)
• Customer lifecycle stage (prospect, active, churned)

Step 4: Schedule and Send

Send broadcasts during your audience's active hours. For Indian audiences, 11 AM–1 PM and 7 PM–9 PM IST typically see the highest engagement. Whaterakt's campaign scheduler lets you set the exact send time and pace (messages per minute) to avoid rate-limit flags.

Step 5: Measure and Optimize

Track these metrics for every campaign:

• Delivery rate: % of messages successfully delivered
• Read rate: % of delivered messages that were opened
• Reply rate: % of recipients who responded
• Conversion rate: % of recipients who took the desired action (clicked a link, made a purchase)

Best Practices

• Frequency: Don't send more than 2-3 broadcasts per week to the same contact.
• Personalization: Use the recipient's name ({{1}} in templates) to boost engagement.
• Clear CTA: Every broadcast should have one clear call-to-action.
• A/B test: Send two variants to small segments and compare before scaling.
• Respect opt-outs: Always honor unsubscribe requests immediately.
