Thank you ShrawanSaxena,I checked the thread and I found it was
interesting for other functionality we might use. But what we need for
now is to know if it's possible to download a file (csv, txt, ...)
containing a list of the recipients (eg. emails) and the deliveries
opened by each of them. Consider that our campaigns are sent mostly to
the same customer base, so we want to know who are "the best and the
worst openers". Thanks PREVIEW
