If I block someone in WhatsApp and then unblock them, will their messages arrive - briefly?

If you block someone on WhatsApp and subsequently unblock them, any new messages they send after being unblocked will be delivered to your device. However, it is important to note that messages sent while you had the person blocked will not arrive in your chat history.

If I block someone in WhatsApp and then unblock them, will their messages arrive - in detail?

When you block a contact on WhatsApp, any messages they send to you will not be delivered until the block is lifted. This is because WhatsApp treats blocked contacts differently than regular users. Here's what happens in detail:

  1. Blocking Process: When you block someone on WhatsApp, their messages are no longer sent to your phone. Instead, they remain undelivered on WhatsApp's servers. The sender will see a single check mark (which indicates that the message was sent), but it won’t turn into two check marks (indicating delivery) or change to blue ticks (confirming read receipt).
  2. Unblocking Process: If you decide to unblock this contact, WhatsApp will attempt to deliver all undelivered messages that were sent during the block period. However, there are a few conditions to consider:

    • Message Limit: WhatsApp imposes limits on how many undelivered messages can be stored and delivered after unblocking. Typically, this limit is around 30 days for text messages and media files. Messages older than this period will not be delivered once the block is lifted.
    • Message Format: Only text messages and certain types of media (like images and videos) are queued up for delivery after unblocking. Other message formats, such as voice notes or documents, may not be stored and could be lost if sent during the block period.
  3. User Notification: The person you blocked will not receive a notification that they have been unblocked. They will simply start receiving your messages again as if nothing had happened.
  4. Group Chats: If the blocked contact is part of a group chat, their messages sent to the group during the block period will also be queued for delivery once you unblock them. However, similar message limits and format conditions apply here as well.

In summary, if you block someone on WhatsApp and then decide to unblock them, any messages they sent during the block period will attempt to be delivered. However, this process is subject to certain limitations and conditions outlined above. It's always a good idea to consider these factors when deciding whether or not to block a contact.
