At ShowMojo, we have spent a lot of time trying to strike the right balance on communication with prospects

Most often, prospect complaints about too much messaging stem from Dynamic Prospect Nurturing emails that go out too often. This happens because the Cross-Marketing Location, Rent and Bedrooms settings on an account are too broad. 

If you live in New York, for example, you don't want to receive notifications about a new rental 10 miles away. Also, if you're looking for a two bedroom, you don't want notifications about a studio apartment that's gone not he market.

If prospects are complaining about too many messages, the first thing to do it review and adjust these ranges in the Other Places You Might Like section on the Gallery and Branding Settings page.
