Want to send 1000 WhatsApp messages online without manually messaging every contact?
You can send 1000 WhatsApp messages at once using the official WhatsApp Business API, provided your account has sufficient messaging capacity and your recipients have opted in to receive messages from your business.
With AiSensy, an official WhatsApp API-based platform, you can upload your contact list, create an approved WhatsApp message template, select your audience and launch a bulk WhatsApp campaign from one dashboard. You can also track message delivery and identify failed messages.
In this guide, we will show you how to send 1000 WhatsApp messages at once, compare the available methods, explain the costs and walk you through the entire process step by step.
Can I Send 1000 WhatsApp Messages at Once?
Yes, you can send 1000 WhatsApp messages at once, but the method you choose matters.
If you are using the regular WhatsApp Business App, classic broadcast lists have limitations that make large campaigns difficult to manage. For businesses that need to message hundreds or thousands of opted-in customers, the WhatsApp Business Platform offers a more practical solution.
WhatsApp Broadcast List vs WhatsApp Business Platform
| Feature | Classic WhatsApp Broadcast List | WhatsApp Business Platform via AiSensy |
|---|---|---|
| Audience | Up to 256 contacts per classic list | Depends on your current account messaging allowance |
| Saved contacts | Recipients generally need to save your number | No requirement for recipients to save your number, but opt-in is required |
| Campaign management | Multiple lists and manual handling | Contact imports, approved templates, audience filters and reporting |
| Cost | Depends on the app feature and availability | Applicable WhatsApp message charges plus provider plan or fees |
Which method should you choose?
For occasional updates to a small group of customers, a classic WhatsApp broadcast list may be sufficient.
But if you want to send 1000 WhatsApp messages online, personalize campaigns and monitor delivery, using the official WhatsApp Business Platform through AiSensy is a better fit.
Note: WhatsApp also offers newer Business App broadcasting features in some markets and accounts. Their availability, limits and pricing may differ from classic broadcast lists.

If your limit is insufficient, complete the applicable KYC or business verification process through AiSensy, if eligible.
Follow our WhatsApp KYC verification guide for more details.
Note: Messaging limits and upgrades depend on Meta's eligibility requirements and aren't guaranteed.
Step 4: Activate an Eligible AiSensy Plan
Choose the most suitable AiSensy plan or trial that supports WhatsApp broadcasting. You can also check the available features and applicable charges on our pricing page.
Step 5: Create a WhatsApp Message Template
Once all the above steps are followed, now you need to create a WhatsApp template message, the message that you will be sending to your users on WhatsApp.
In order to do so, you can open the Template Messages section in AiSensy and create your message.
In your WhatsApp Template Message, you can add text, media, personalization variables or CTA buttons as needed.
Step 6: Import Your WhatsApp Contacts
Prepare a CSV file containing your customers' WhatsApp numbers with the correct country codes.
Make sure your contacts have opted in, remove duplicates and upload the contacts to AiSensy.
Step 7: Recharge Your WhatsApp Conversation Credits
Check your available WhatsApp Conversation Credits (WCC) and recharge if needed.

Step 8: Select Your Audience and Create a Campaign
Open the Campaigns section in AiSensy and create a new WhatsApp broadcast.
Select your uploaded contacts, choose an approved message template and fill in the campaign details.

Once verified, launch your campaign or schedule it for later if your plan supports scheduling.
Step 10: Track Your WhatsApp Campaign Performance
Open Campaign Analytics in AiSensy to monitor sent, delivered, read, replied-to and failed messages.
Review delivery failures and use the available insights to improve your future campaigns.
How Much Does It Cost to Send 1000 WhatsApp Messages?
The cost of sending 1000 WhatsApp messages depends on the message category, recipient country and the platform you use.
For example, if you're sending a promotional offer to 1000 customers in India using AiSensy, the marketing message rate is ₹1.09 per delivered message.
Here's how the cost works:
| Details | Cost |
|---|---|
| Message category | Marketing |
| Number of recipients | 1000 |
| Rate per delivered message | ₹1.09 |
| Total message charges if all 1000 messages are delivered | ₹1,090 |
This ₹1,090 example covers the marketing message charges only. Your AiSensy subscription, applicable fees and taxes may be additional.
WhatsApp charges for applicable delivered messages, not simply for uploading 1000 contacts or attempting a campaign. If fewer messages are delivered, the message charges may be lower.
Rates also vary by recipient country and message category. You can check the latest charges on the AiSensy Pricing page.
Can You Send 1000 WhatsApp Messages for Free?
You can create a free AiSensy account and explore the available WhatsApp Business Platform features. However, sending 1000 marketing messages isn't automatically free.
Marketing broadcasts are subject to applicable message charges, and broadcasting access depends on your plan or trial.
The monthly free service-message allowance is separate from marketing broadcasts. It does not mean that businesses can send 1000 promotional messages for free.
Why Are Some WhatsApp Messages Not Delivered?
Even when you use the official WhatsApp Business Platform, not every message is guaranteed to reach its recipient.
Here are some common reasons a WhatsApp broadcast may fail:
- Incorrect phone numbers
- Messaging limit restrictions
- Template issues
- Insufficient message balance
- Recipient eligibility
- Account quality or policy restrictions
What Should You Do If a Campaign Fails?
Open your campaign analytics and review the failed-message count and available error information.
Check the affected contacts, message template, sender status and account balance before deciding whether another attempt is appropriate.
Avoid repeatedly retrying messages without identifying the reason for failure.
For future campaigns, maintain a clean, opted-in contact list and monitor delivery performance regularly.
