Prefer phone/secondarily text always, as said above, can't be arsed with AW profiles with no phone no etc, move on to the next
Phone/text I find easier, avoids potential prob of unanswered emails, esp if you are looking for soonest/same day punt, also easier to establish what's on offer/discuss requirements/scenario/outfits to be worn/location etc
My opinion anyway, altho I'm a bit of an old fogey, I go back to the days of phone box cards for my original punts!
Best of luck
