WhatsApp is a great program for business promotion and marketing. It streamlines and personalizes customer communications and has a high engagement rate among users.
WhatsApp is good for messaging customers individually. But if you really want to maximize your business's time and resources, consider sending bulk messages.
Bulk messaging helps you connect with customers on a larger scale. You can send an unlimited number of characters, photos, videos, and other media, customize messages for each user, and send private messages to multiple recipients at the same time.
So, what exactly goes into bulk messaging on WhatsApp? Where do you begin?
Let's find out.

What is a WhatsApp Bulk Message?
WhatsApp bulk messages are sent to many recipients at the same time.
Instead of individually contacting each customer — which takes hours of your time — you can:
- Add your recipients to a list
- Type up one message
- Send it to everyone with one click
Users receive your bulk message as a private message. (They can't see who else is on the recipient list).
Even better, there's no limit to the number of recipients of a bulk message. And with WhatsApp API, even those who haven't saved your WhatsApp number get notified.
WhatsApp Bulk Messaging for SMEs & Enterprises
WhatsApp bulk messaging was initially only available to consumers. But now, businesses use it for their outbound marketing initiatives.
Many businesses prefer WhatsApp over other communication channels because of its quickness and simplicity.
WhatsApp has a few bulk messaging options for different types of companies:
- Mid-sized businesses and enterprises with significantly larger customer bases can choose WhatsApp Business API
- The API enables bulk messages
- However, it requires you to use WhatsApp's message templates for mass messaging
- SMEs can use the WhatsApp Business app
- The app broadcasts to 256 customers

Factors to Consider Before Sending Bulk Messages on WhatsApp
WhatsApp uses phone number tiers, status, and quality ratings to safeguard its users from spam and improve bulk communications.
Your specific bulk message capabilities depend on the following factors:
Phone Number Tiers
WhatsApp API establishes phone number tiers. This dictates how many recipients you can send bulk messages to.
So, if you're in a higher tier, you're allowed to communicate with more individuals in a rolling 24-hour period.
The result: You grow your audience and improve marketing/sales.
How Do You Upgrade Your Whatsapp Phone Number Tier?
To boost your phone number tier, send twice the number of messages permitted for your tier in seven days.
Here's an image to help you understand the process:

Phone Number Rating & Status
Customers give you a quality rating based on your messages over the last seven days.
Your quality rating falls into three categories:
- Green — High quality
- Yellow — Medium quality
- Red — Low quality
Why is this important?
Well, your quality rating determines your phone number's status. And your status dictates your sending capacity.
What Causes a Low Rating?
Your phone number's rating decreases any time it's reported or blocked. Being repeatedly reported/blocked gives you the lowest quality rating.
Your rating may also go down if you exceed your messaging limit.
What Happens if Your Quality Rating Is Low?
When your phone number reaches low quality (due to being reported/blocked), your status changes from "Connected" to "Flagged."
- While Flagged, you can't raise your phone number tier
You have seven days to improve your quality rating:
- If your rating improves to high or medium quality — your status returns to Connected, and your messaging limit tier remains unaffected
- If your rating doesn't improve — your status returns to Connected but with a limited messaging capacity
If your rating decreases because you surpassed your messaging limits, your status becomes "Restricted." Being Restricted limits your messaging capabilities:
- You can't send any messages in the first 24 hours
- You can't send WhatsApp bulk messages to newly created Unique Contacts
- You can only respond to conversations initiated by customers
How Do You Avoid Low Ratings?
Send only high-quality WhatsApp bulk messages to maintain a good quality rating. Providing great customer service via WhatsApp lets you continue to send messages freely.
