Will the contact see that I unblocked them in WhatsApp - briefly?
No, a contact will not be notified if you unblock them on WhatsApp. Once you've unblocked someone, you can view their last seen status and any messages they send to you, but there is no notification or alert sent to the contact indicating that they have been unblocked.
Will the contact see that I unblocked them in WhatsApp - in detail?
When a user blocks someone on WhatsApp, all communication between the two parties is effectively halted. However, if you decide to unblock this person, it's natural to wonder whether they will be notified of your action. The detailed answer to this question is multifaceted and depends on several factors.
Firstly, WhatsApp does not send a specific notification to the user when they are unblocked by another contact. This means that if you decide to lift the block, the other person will not receive an alert or message informing them of your decision. The unblocking process is designed to be discreet, preserving the privacy and autonomy of both parties involved.
Secondly, while there may not be a direct notification, certain changes in the communication status might hint at the unblocking. For instance, if you had previously blocked someone, messages sent by that person would not reach your phone and would remain undelivered. Once you unblock them, those pending messages will start to arrive in your chat history. This could potentially alert the other user that something has changed, but it is not a definitive indication of having been unblocked.
Additionally, if you attempt to initiate contact with the person after unblocking them—such as sending a message or making a call—they will be able to see your status and any recent changes in your profile picture or about section. This visibility could also serve as an indirect clue that communication barriers have been lifted.
In summary, while WhatsApp does not provide explicit notifications for unblocking actions, certain shifts in message delivery and visibility of user status can subtly indicate a change in communication status. It is always wise to be mindful of these nuances when deciding whether to unblock someone on the platform.
