How do I send my property to the portals?

First of all, the property would need to be live:

To send the individual property to the portals, you would click the 'Marketing Alerts' tab on the right-hand side and then 'Export All':

To run your feeds for all properties, you would go to the 'Marketing' tab at the top > tick to highlight all portals > click 'Select' then 'Run':

The system will also automatically synchronise your live property listings (i.e. those which are "on the market") with the portals each night.
