No other realty eflyer offers a built-in poll question feature.
On MondoFlyers, your poll question is prominently displayed in the upper-right corner of your email flyer, so even if you do not have a question per-se, it's a superb way to spotlight 2 or 3 key selling points of your listing.
And the total responses are included on your delivery report.
Don't ask the "obvious". Asking "Do you have a buyer for this home?" will get little if any response. Ask about specific features, instead, to get them thinking about those benefits.
