If I block a contact on WhatsApp, will they still receive messages from me - briefly?

When you block a contact on WhatsApp, they will not receive any of your messages or calls. The block effectively prevents all communication between you and the blocked user.

If I block a contact on WhatsApp, will they still receive messages from me - in detail?

Blocking a contact on WhatsApp is an effective way to prevent unwanted interactions and notifications from that specific user. However, the act of blocking does not affect the delivery of messages you send prior to implementing the block. Here's a detailed breakdown of what happens when you block a contact:

  1. No New Messages: Once you block a contact on WhatsApp, they will no longer be able to send you any new messages or calls. This means that their attempts to communicate with you will fail, and they won't receive any delivery notifications indicating that their message has been read or received.
  2. No Delivery Notification for Blocked User: If the blocked contact tries to send a message after you have blocked them, WhatsApp will not deliver that message to your phone. As a result, the sender will see only one checkmark (indicating that the message was sent but not delivered), and they won't receive any read receipts or delivery notifications.
  3. Messages Sent Before Blocking: It is important to note that blocking a contact does not retroactively affect messages that were sent before the block was implemented. Any messages sent by you to the blocked contact prior to the block will still be delivered and visible to them, as WhatsApp does not alter or recall previously sent messages upon blocking someone.
  4. Your Visibility: When you block a contact, your status updates, profile picture changes, and any other information you share on your status won't be visible to the blocked user anymore. They will no longer see any updates from your account.
  5. Group Dynamics: If you and the blocked contact are part of the same WhatsApp group, they will still be able to see your messages within that group until they are removed or leave the group themselves. However, if you remove them from the group, they won't be able to view any future messages sent by you in that group.

In summary, blocking a contact on WhatsApp effectively stops new communications from that user but does not prevent the delivery of messages sent before the block was implemented. It is a powerful feature for managing unwanted interactions while maintaining control over your messaging environment.
