Muster is a great overall value. It provides us with everything we need in strategic grassroots advocacy software. Muster takes it to the next level by better informing our Congressional engagements, providing us analysis on which districts receive our correspondence. This allows us to tailor our messaging and make in-roads with members whom we may not have had prior relationships with.
We selected Muster to replace a different grassroots advocacy platform. While we are not using it to its full capabilities, we like that, as we contemplate future software acquisitions, Muster is flexible and expandable to meet potential future needs. It allows us to mobilize our members to contact their elected officials with clear, consistent messaging and an uncomplicated and user-friendly experience for administrators and users.
After using a number of other grassroots platforms and being dissatisfied with their high costs or poor service, Cigar Rights of America started working with Muster in hopes of getting a serviceable product at a reasonable price, and they have truly exceeded our expectations!
Muster offers more flexibility with powerful features that drive value for organizations looking to impact public policy.
