No, there is not a bulk email list available for Minnesota legislators. While email is an effective way to contact your representative or senator, it is best to address your concerns to the legislators that represent you.
Every member of the Legislature has an email address based on the member's name. For example, Representative Jane Doe's email address is firstname.lastname@example.org. Senator John Doe's email address is email@example.com.
To find out a specific member's email address, you can look several places. The House and Senate websites have pages for each member that includes his or her email address (Members of the House of Representatives and Minnesota Senators). The Official Directory of the Minnesota Legislature (often referred to as "the red book") and the Members Directory ("the green book") contain contact information, including email addresses, for all legislators. To receive a free copy of the red or green book, or to ask a member's email address, call either House Public Information Services at 651-296-2146 or Senate Information at 651-296-0504.
