Response Processing Center review: life insurance

I received a flyer from:

Response Processing Center
PO Box 3015
Indianapolis, Indiana 46209-9302

It read in part,

2019 Benefit Information Enclosed for Nevada Residents Only
Open immediately - Do Not Delay

I do not want to receive anymore mail from this entity. If I do not receive written communications from them, within 90 days, to suspend all further correspondence, I will be forced to contact my attorney, W J Thomas Ferguson of Seattle, Washington and issue a Cease and Desist Order from the court.
