How to delete messages

How can i delete old messages in my THS inbox ? Answers from owners who answered negatively or from sitters who applied and my own messages?
What is the différence between archived messages and not archived?

Hi @Provence.

At the moment there is no way to completely delete messages from the website you can only archive them. This means they will be moved to the archive folder so your inbox can be more organised, with the most recent applications and messages from other members in the inbox.
Archived messages are ones you no longer need, like unsuccessful applications, old sits etc.

Hope that helps.
