Very helpful customer service; responsive, helpful, and professional. Muster offers excellent services, like the "circle back" feature, which allows us to re-send an alert, but only to those who did not respond the first time, meaning that our advocates will not be inundated with emails

Muster ist einfach zu verwenden und der Kundenservice ist schnell und freundlich.

Muster provides us with excellent campaign setup capabilities for our advocacy campaigns. We can email our list or reference a URL in separate email system and it automatically sends the email to the right Member of Congress.
