I can actually see the benefit of not having your info on email listing updates....it's very non threatening if it's just the listing. Does not make them feel like they're being pressured/sold into working with somebody in particular. Yet when it comes time to click they end up likely to click on your showing/inquiry buttons....

I would not be surprised if this is as or more effective for conversion and loyalty to your listing updates.

combine with a carefully thought out drip campaign that has mega useful/helpful original articles that do not overwhelm the buyer in terms of frequency and it could be the perfect combo to maintain a functional relationship for the epiphany marketing experience.
