Easy Way to Mobilize Your Grassroots to Tell their Reps Their Opinion

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.

What they liked
  • Easy to use
  • Meets our needs for advocacy and geocoding people to their correct rep
Room for improvement
  • Doesn't measure twitter activity
  • Can set up action center for Twitter, but software doesn't currently have ability to measure tweets generated
Switched From

P2A wasn't working on all phones; we had a hard time collecting cell phone numbers; we have more email addresses. Also more costly.

Why they chose it

"The right mix of options vs. price for what we were looking to do: impact policy through grassroots action."

Effective Advocacy Tool

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.

What they liked
  • 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
Room for improvement
  • 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

Muster wins!

Verified reviewer

What they liked
  • Muster allows us to succeed where Mailchimp failed
  • We have appealed to our members to contact their representatives in the past
  • Now that Muster has made that nearly automatic, we see that members are now taking action
  • And liking the experience
  • More than changing the course of discussion in the legislature, Muster has given our members the ability to get to know their delegates, and for their delegates to get to know them
  • Linking up constituents with their representatives is fundamental to our democratic way of governance
  • Not only is Muster an easy to use package, but the staff is friendly and responsive to queries
  • We have used Muster as an integrated solution, combining it with MailChimp, with Facebook, and with Twitter
  • And according to our growing membership this integrated approach is working
  • While we are working with Muster to make the software experience even more useful, we have no hesitation in recommending this particular package for anyone's advocacy software needs

Easy way to mobilize our members

Great experience! Great customer service.

What they liked
  • Ease of use and the personalized customer service
  • The guys at Muster always respond quickly and get the job done well
Room for improvement
  • Updating contacts can sometimes be a pain
  • It would be great if somehow we could integrate information on users of this software with our database in a seamless way
  • That may have more to do with our database than with Muster

Muster is a Must-have

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.

What they liked
  • 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
Room for improvement

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

Political Action is Easier

We are a professional association working to pass state legislation and this is the first political action software we have used. So, far it has been going very well and the learning curve for the system is very modest. As we build our database of contacts, we're also gaining confidence in our ability to efficiently and effectively mobilize our members to contact key legislators at just the right time.

What they liked
  • Muster is very easy to use and the ability to identify contacts by legislative district is extremely helpful
  • The ability to create Calls to Action with accompanying message templates looks very promising and will get much more use as we get closer to the upcoming legislative session
Room for improvement
  • While this system will identify contacts by legislative district, it doesn't currently identify the legislative district of an individual contact
  • We understand that is likely to be added in the future and will be much appreciated
Why they chose it

"Ease of use. Personal contact and customer service. Price point."

We needed a simple and straightforward 'contact your legislator' tool. We got that and more.

We increased our grassroots lobbying presence from practically non-existent to one of the most active groups in the state of Iowa. We also grew our activist network 4-fold, with the help of a lot of online ads that drove new activists to the action page.

What they liked
  • It's very simple, you can begin using it almost immediately after signing up, and you can track and monitor every email/letter/phone call you produce
  • We signed up thinking we would only use the email action tool to get members of our organization more involved in grassroots lobbying
  • Instead, we used every tool available and grew our activist network 4-fold (with the help of a lot of online advertising to drive people to the action page)
Room for improvement
  • When you create a new email action for users to click on and contact their lawmakers you can edit the landing page (which describes the purpose of the action and some talking points) but not the form letter
  • So if you want to freshen up a form letter you have to create a new email action
  • This was just a minor inconvenience

Enables Advocacy Engagement with Members at a Reasonable Rate

A positive experience. It's less expensive than some of the other options out there and it gave us what we needed to increase advocacy engagement with our members.

What they liked
  • It gives us the ability to engage with our members making it easy for them to contact state representatives and officials about issues important to our industry
  • The interface was simple and not too complicated as well
Room for improvement
  • It has limits
  • There's a need to recreate the campaign when you want to resend
  • In some cases, there's also an issue with proper district borders as it pulls from map coordinates and they can sometimes be slightly off
  • For example, I'm right on the border with another district so it didn't display my own district properly
  • This isn't a common problem but it does happen sometimes and they're working on it
