I don’t think it’s possible & is really annoying because it would be extremely useful. It can’t be too hard to add as a function, and it has been discussed before. If you have a conversation with a home owner in your in box and decide it’s not for you, you can move it to the archive. But scrolling through sits that don’t match criteria can’t be marked up so we don’t see them again. Another housesitting website has a smiley face or frown that can be clicked on….
Here’s a former discussion on the forum that may be of interest:
However, watch the website as I’ve received an email asking if I’d test the new Inbox. Apparently “managing applicants and applications is about to get a whole lot easier….”
so hopefully permanently deleting sits that aren’t on our radar will be one of the improvements! We can only hope!
