Send Mark a physical postcard — printed on heavy cardstock and mailed by USPS to the Wisconsin State Capitol. State legislators hear from far fewer constituents than Congress does, so a single card carries real weight.

Capitol Mailing Address
State Senator Mark Spreitzer
Wisconsin State Capitol
Madison, WI 53702
Mail to Wisconsin legislators is delivered to Wisconsin State Capitol in Madison, where legislative staff log and route constituent correspondence. State capitols receive a fraction of the mail volume that Congress does, and unlike mail to Washington D.C. it is not irradiated — so a card addressed here arrives faster and competes with far less.
