If you block someone on WhatsApp, they will not be able to send you messages. This is because blocking effectively ends all communication between the two parties.

If you block someone on WhatsApp, can they send you messages - in detail?

When you block a contact on WhatsApp, the primary effect is that the blocked user will no longer be able to send you messages or see your online status and profile picture. This action effectively cuts off communication from their side. Here's a detailed breakdown of what happens:

  1. Message Sending: Once a user is blocked, any messages they attempt to send to you will fail to deliver. They won’t receive any error notification indicating that the message was undelivered; it simply won't reach your inbox. This ensures that you are not disturbed by unwanted communications.
  2. Status and Profile Updates: The blocked user won’t be able to see your last seen status, online status, or any changes you make to your profile picture. Similarly, you won't receive updates about their status or profile picture. This mutual blocking of visibility helps maintain privacy on both sides.
  3. Calls: Blocking a contact also prevents them from calling you via WhatsApp. Any call attempt made by the blocked user will be unsuccessful and they won’t receive any indication that the call failed to connect.
  4. Group Interactions: If you are both part of a group, the blocked user can still send messages within the group, and you will receive them. However, if you remove the blocked user from all groups, they won't be able to join back without your explicit permission.
  5. Visibility in Contacts List: The blocked contact won’t disappear from your contacts list but will no longer show up as a contact within WhatsApp. This distinction helps you maintain an organized contacts list while ensuring that the blocked user is restricted from initiating any form of communication with you.
  6. Reversibility: It's important to note that blocking a contact on WhatsApp is reversible. You can unblock the contact at any time if you decide to re-establish communication. Once unblocked, all previous restrictions will be lifted and normal communication channels will be restored.

In summary, blocking someone on WhatsApp effectively prevents them from sending messages or making calls directly to your account. This feature is designed to protect users from unwanted interactions while maintaining the flexibility to re-establish contact if desired.
