If I delete a contact in WhatsApp, can they still write to me - briefly?
When you delete a contact from your phone's address book, it does not affect their ability to send messages to you on WhatsApp. However, the message will appear as coming from an unknown number or contact.
If I delete a contact in WhatsApp, can they still write to me - in detail?
Deleting a contact from your WhatsApp does not prevent them from sending you messages. When you delete a contact, it simply removes their information and the chat history from your device. However, the conversation remains on WhatsApp's servers, allowing the other person to continue messaging you as if nothing has changed.
This is because WhatsApp uses phone numbers as unique identifiers for each user rather than relying solely on contact names or information stored in your device’s address book. When someone sends you a message through WhatsApp, it is routed using the phone number associated with your account. Therefore, even if you have deleted their contact details from your phone, their messages will still be delivered to your WhatsApp inbox based on the phone number they are sending the message to.
Additionally, deleting a contact does not block them. If you wish to stop receiving messages from someone, you would need to use WhatsApp’s blocking feature. Blocking a user prevents them from seeing your online status, reading receipts, or any changes made to your profile picture. It also stops their messages from reaching your inbox.
In summary, while deleting a contact removes their information and chat history from your device, it does not inhibit them from sending you messages on WhatsApp. If you want to prevent someone from messaging you, consider using the blocking feature provided by the application.
