Sending bulk WhatsApp messages can help you reach many customers quickly. But if you want your campaign to work well, you must track the right performance indicators. These KPIs show how your messages behave after you send them and help you understand where improvements are needed. Let us look at the most important KPIs and how they can guide your campaigns.

Delivery Rate
Delivery rate tells you how many of your messages reached the user successfully. If the number is low, it may be because the contact list has invalid numbers or the receiver has blocked the business account. By checking this KPI regularly, you can find problems with the audience list and take corrective steps.
Read Rate
Once a message is delivered, the next factor you must watch is the read rate. It shows how many people opened and viewed your message. A high read rate tells you that the contact list is active and the users are interested in receiving your updates. If this number drops, try changing the message format or the timing of your campaign.
Response Rate
Response rate helps you check how many users replied to your bulk WhatsApp messages. It directly reflects the level of engagement. If people respond, the message copy is working well. If the response is low, try improving your call to action or simplifying the message content. Sometimes even changing the greeting or structure can improve this rate.
Click Through Rate
If you share links in your messages, click through rate becomes a very important KPI. It tells you how many people tapped on the link and visited your page. When this number is strong, your content is clear and helpful to the reader. If you find that clicks are low, you may have to change the button copy or the placement of the link.
Conversion Rate
This KPI reveals how many users completed the action you expected after clicking the link. It can be a purchase, booking, registration or any other target. Conversion rate gives you a complete picture of how your campaign performed after the user moved past the message. If this rate is poor, the issue might be on the landing page or the offer itself.
Unsubscribe Rate
Although WhatsApp does not show a direct unsubscribe option, users can block your number or mark it as spam. A rise in this activity reflects dissatisfaction. If this number goes up, you must change the frequency or simplify the content. Sending too many messages or using pushy language can drive users away.
Cost Per Message and Cost Per Conversion
These KPIs help you understand the financial side of your campaign. Cost per message gives you a clear picture of how much each message costs. Cost per conversion tells you how much you spend to get one completed action. By tracking these KPIs, you can manage your marketing budget effectively and plan future campaigns with better accuracy.
Message Delivery Time
This KPI tells you how long it takes for the message to reach users. Slow delivery can affect response and read rates. If the delivery time increases, check whether the campaign has too many messages in a single batch or if there are issues with the service provider.
Final Thoughts
Tracking these KPIs will help you understand how your bulk WhatsApp messages perform from start to finish. Each KPI points to a different aspect of your campaign. When you monitor them regularly and make changes based on the results, your WhatsApp marketing will steadily improve and deliver better outcomes.
