In step 7 of the Mailing
wizard, the aggregated sort can be entered. This means that the mailing
wizard can filter out all guests who are listed in the system but who
have not stayed in the hotel, e.g. for an aggregated sorting on the total
nights.
The same applies to the other sorting options. This sorting can also be executed in ascending order. One can proceed to Step 8 of the mailing wizard after the aggregated sorting options have been entered. This can be done by clicking on the black right arrow.
