WhatsApp ensures a secure and quick delivery of messages on the platform. However, users may experience delivery issues occasionally with some messages.

Users often report delays in message delivery, which can occur due to several technical reasons and in-app glitches. Therefore, it is essential to understand why it happens to effectively handle it.

In this post, we will first discuss the causes and then the various techniques you can use to address the WhatsApp message not delivered issue.

Part 1. What Causes WhatsApp Messages Not to be Delivered?

WhatsApp messages are normally delivered immediately after they are sent. However, some messages experience delayed or failed delivery due to various issues between sender and receiver.

Let’s have a look at each side individually:

Reasons from the Sender’s Side

You block the receiver: When you block a contact on WhatsApp, you don’t receive any messages or calls from their end. Similarly, any messages you send them are not delivered.

Your network is not working well: WhatsApp messages need a strong network connection for delivery. In case of network connection issues, your messages don’t get delivered right away. A weak or unstable network often leads to delayed delivery.

Software issues or bugs: Technical glitches, outdated software, or buggy beta builds can hinder your message delivery on WhatsApp. These issues are hard to identify and require thorough assessment.

Corrupt WhatsApp Issues: Some WhatsApp updates or version incompatibilities may affect your message delivery.

Device Problems: Any fault in your device can also cause WhatsApp message delivery issues.

Reasons from the Receiver’s Side

The Receiver Blocks You: Your message will not get delivered if the receiver has blocked you. To check if the receiver has blocked you, check if his availability is visible online. Next, check if you can see his last seen timestamp. If there is a single tick for long, you can call that contact and see if the person attends the call. If you are unable to see the last seen status and profile updates, you get a single tick on the sent messages, and you receive no response on the call, it likely indicates that the receiver has blocked you.

The Receiver’s Phone is Turned Off: When you send messages to a receiver whose phone is powered off, he can’t receive your messages. Until that receiver switches the phone on, your message will not be delivered. You will just see a single tick with your message until the receiver turns on the phone.

The Internet of the Receiver is Disabled: WhatsApp messages are sent over an Internet connection. Without network access, the receiver cannot receive the messages you send. So, until they turn on their internet, your messages display a single tick.  

The Receiver Uninstalled WhatsApp: If the receiver has uninstalled WhatsApp or deactivated the account, all the messages that you send don’t get delivered. However, there is no way to check if the receiver has deleted the account other than asking directly.

Note: It is important to understand that you can only control your own device and WhatsApp account. You can’t manage the activities on the receiver’s end. Therefore, we have covered some effective techniques in the next section to fix WhatsApp messages not delivered problems that occur on your side.
