How to Target the Right Legislators with Your Advocacy Mailing Campaign

Many organizations conduct grassroots advocacy campaigns to mobilize their members. If you’ve ever had to organize a mass mailing campaign, you know how much of a headache it can be to match each constituent with the right local, state, and federal legislators. Finding information for elected officials is surprisingly hard, especially when you need to do it for hundreds or thousands of addresses. Using a manual lookup service could take days or even weeks to do this.

Our new District Match tool cuts time down to minutes. District Match allows you to easily match bulk spreadsheets of addresses to our extensive database of elected official contact info.

Here is a step-by-step tutorial (with screenshots) on how to target the right legislators with your next advocacy mailing campaign. For a shorter version, check out our infographic on 10 Steps to Target Legislators with Your Advocacy Campaign.
