No, the contact will not be notified if you unblock them on WhatsApp. You can safely unblock someone without them knowing.

If I unblock a contact in WhatsApp, will the subscriber see it - in detail?

When you unblock a contact on WhatsApp, the subscriber will not be automatically notified that they have been unblocked. WhatsApp prioritizes user privacy and has designed its system to ensure that such actions remain discreet. This means that if you had previously blocked someone and then decide to unblock them, they will not receive a notification or any indication that their status with you has changed.

However, there are some nuances to consider:

  1. Message Delivery: After unblocking, you can send messages to the contact as usual. The contact will receive these messages normally, without any indication that they were previously blocked.
  2. Status Updates: If your status updates (like profile picture changes or "About" section edits) are set to be visible to everyone, the unblocked contact will see these updates just like any other contact on your list.
  3. Mutual Blocks: If both you and the contact had blocked each other, unblocking them will not automatically add them back to your contacts list or show their messages in your chat history. You would need to manually add them again as a new contact or wait for them to initiate a conversation.
  4. Last Seen: The "last seen" feature will only update if you have viewed the contact's profile after unblocking them. If you haven't done this, they won’t see any change in your "last seen" status.

In summary, while WhatsApp ensures that the act of unblocking remains private, it is important to be aware of how other features might indirectly reveal changes in your contact list or interactions.
