It varies with the client. 

Hi Will -- it depends.  Some more than others.  Some not at all.  I could do better at staying in touch with face-to-face and phone calls instead of more passive delivery methods.  I'm not a big phone marketing person.

Not as often as we should.

Monthly to quarterly, depending on their known situation.

Not enough Will, I should do it more often

A+'s  monthly ( I naturally talk with these folks).

A's    Bi-monthly

B's    Bi-monthly stretches to Quarterly due to quantity.

C's    Quarterly stretches to semi annually due to quantity.

Calls are part of my daily Power Hours of Prospecting.

At least quarterly.

"What? I'm supposed to call my past clients!"

Not as often as I should.

Will Hamm - not all of them are A+. They are called more often than those who are B clients. 

Buffini & Company has a simple definition of A+ client - one who is your advocate and has given you multiple referrals.

Will - Not often enough. This is something that I am working on.

varies with the client, but at least a couple of times a year.  Well except for the 3 people that I was glad to see go in my career.

They get cards about 5-6 times a year, I call them about 3 times a year.

I usually don't call my past clients.

Each client is different but there is a contact each month with a news letter.
