Just got off the phone - it was really simple and quick (I think I was on the phone for less than 10 mins total)
Called the number and mentioned the e-mail and they took my information and then transferred me to a sales rep. He asked me if I had ever stayed on property and if so where, if I had any upcoming trips booked and how often we visit WDW. Then went over the details at a very high level: Minimum buy-in ($17,600), what that gets you (100 points - about 4-8 nights a year with it), annual dues ($6.19/point/year), and a few facts (no blackout dates, can use towards cruise, have 4,000 non-Disney properties you can use it at, etc.). And then said he already processed sending out the gift card (would take 2-4 weeks) and was sending some other info.
that's it - no pressure at all, didn't even ask me if I was interested/thinking about it/anything
