What are WhatsApp bulk messages?

WhatsApp bulk messages, also known as WhatsApp broadcasts, allow you to send a single message to multiple recipients at once, making it easy to share promotions, newsletters, updates and reminders.


This helps keep your brand top of mind, drive repeat engagement and ensure timely communication with your customers.


By reaching them directly on WhatsApp, you can boost conversions, reduce missed opportunities and build loyalty with minimal effort.

Bulk messages on WhatsApp Business App vs API

Not all bulk messages are the same—WhatsApp Business App and WhatsApp Business API have different capabilities and rules.


For businesses that need more than basic bulk messaging, WhatsApp API enables scalable broadcasts, automation and detailed audience segmentation.

WhatsApp bulk messages vs click to WhatsApp ads: When to use which

Unlike SMS or email blasts, you can’t send bulk messages to just anyone over WhatsApp API. 


Meta enforces strict rules to protect users from spam and violating its guidelines can lead to account restrictions or bans. 


Instead, businesses looking to reach cold or new audiences can grow their customer base with click to WhatsApp ads.

These ads are shared on Meta channels like Instagram and Facebook, driving prospects who click on them directly into a WhatsApp chat with you.


Only then can you re-engage these contacts with WhatsApp bulk messages and nurture them to convert or buy again.

How to send WhatsApp bulk messages

Since WhatsApp API does not have a frontend interface to send or receive messages, you will need to connect it to a messaging platform like respond.io. Then, you’re ready to broadcast at scale.

Step 1: Choose your audience

Import and segment opted-in contacts based on traits like purchase history, location, membership tier or language for targeted messaging.

Step 2: Create a broadcast campaign

Select a Meta-approved WhatsApp template. Broadcast to Messenger, Telegram and more simultaneously for maximum reach on respond.io.

Step 3: Send and track performance

Personalize messages with relevant details. Then, schedule delivery and track metrics for future optimization.

How much do WhatsApp bulk messages cost?

WhatsApp API is a cost-effective channel for broadcasts and marketing—if you use the right messaging platform.

Meta fees: Conversation-based pricing depends on the type of conversation.


WhatsApp Business Solution Provider fees: Some WhatsApp BSPs impose setup fees, maintenance fees or message markups. On respond.io, pay only what Meta charges you.
