Muster has been great to work with and made our efforts to engage our members in advocacy efforts simple and straightforward.

The product is streamlined and easy to use. The team at Muster is customer service driven and great to work with.

Looking forward to Muster version 2.0 and the new functionality it will provide.

We were able to give grass roots an easy way to reach their reps - it was so easy that our action center was shared by several allied organizations to their followers.

Easy to use. Meets our needs for advocacy and geocoding people to their correct rep.

Doesn't measure twitter activity. Can set up action center for Twitter, but software doesn't currently have ability to measure tweets generated.

Using Muster has increased our reach on issues that matter most to our members. Our members find it easy to click through the prompts and customize their message to legislators, and they are able to easily share the Action Alerts among their networks as well.

Muster is an effective tool for engaging our association membership to participate in advocacy activities and engage their elected officials. With a few simple clicks, it makes it easy for people in our network to reach out and advocate.

There is not a way to modify the text in the messages we send to legislators—ie, bolding certain phrases, italicizing legislation, or bulletin key takeaways. This is disappointing that the letter the legislator receives is not eye-catching in that way, where they can easily pull out the key features of the message.

We began using Muster in its early days as a tool for us to build a grassroots advocacy organization. Before Muster, we used MailChimp, which is great for sending email, but it doesn't provide the key functionality of calling your list to specific, political action and then tracking the outcomes. Muster was absolutely critical to our success when, last year, our city council passed the final vote to begin building rapid transit infrastructure for our city. Now, as our organization grows and matures, Muster's features allow us to keep our supporters engaged and keep our officials on the right track.

Muster is great for the following reasons: Excellent underlying data that makes segmentation and targeting your list simple. The team is fantastic at supporting their product. Sending quick updates is easy.

Muster could be better if: More integrations Greater ability to customize emails Organization-facing mobile apps for managing lists, signups, calls to action.

User-friendly with an easy to use interface. Economical - well suited for a growing organization. Very responsive team, actively seeking feedback and making changes to suit our campaign.

Data organization can be tricky. Large numbers of contacts can slow down the interface.
