Here in Miami, we have some of the most stringent building codes in the United States owing to the frequency at which we experience tropical cyclones.

A helicopter pilot on the Santa Monica Airport Tower frequency cautioned he was heading out over the water to chase a stolen lifeguard boat.

For example they said no pests, but selected no testing had been done, they didn't know how old the septic tank was, when it was last pumped, or the frequency, and didn't know age of roof. 

I think success in longer term direct mail campaigns is more about consistency in communication than mailing frequency tactics.Probates are the one lead type where I've seen people be successful by changing the frequency.

I've had reasonable success with these methods working the same list (currently have 2 deals underway and many more mild-medium leads in the funnel).I'm wondering what everyone does in terms of a long-term marketing mix, namely frequency and method of contact.

On the other axis you have a probability/frequency scale ( how likely is this thing to occur?

The signal transmits a much shorter distance due to higher frequency and shorter wavelengths than previous technology.

In doing that the frequency of situations like this will be greatly reduced.

Based on your reply, seems to me that you are under the impression that you have to "hire" and pay the core team on certain frequency...which is not the case, even though they obviously don't work for free.

What is the preferred method/frequency of communication?
