If you block a contact in WhatsApp, will they see that the messages have been sent - briefly?
When you block a contact on WhatsApp, they will not be able to see if you've read their messages or if your status has changed. This is because the block prevents any communication between you and the blocked contact.
If you block a contact in WhatsApp, will they see that the messages have been sent - in detail?
When you block a contact on WhatsApp, several changes occur in your communication with them. One of the key aspects is the visibility of message delivery statuses.
Firstly, it's important to understand that blocking a contact doesn't retroactively change the delivery status of messages sent before the block was initiated. If you have blocked someone after they have seen your messages, those messages will still show as delivered in their chat history. However, any new messages you send after blocking them will not display a "Sent" or "Delivered" status for you.
For the recipient, when they try to contact you after being blocked, WhatsApp won't notify them that their messages were sent but not delivered. Instead, they might see only one checkmark (indicating message sent) and no second checkmark (indicating message delivered). This is a common indicator for users that their message might not have reached the recipient due to various reasons such as network issues or the recipient having changed their phone number.
Additionally, if you block someone, they will not be able to see your last seen status, online status, or any changes to your profile picture. They can still call you, but the call won't go through and they will receive a message stating that the caller is unavailable.
In summary, while blocking a contact on WhatsApp does affect the visibility of message delivery statuses for future messages, it doesn’t change the delivery status of previously sent messages. The recipient might notice some irregularities in their communication with you but won't be explicitly notified that they have been blocked.
