Muster Advocacy Software Terms of Service

Effective May 11, 2023

This is a legally binding agreement, and these Terms of Service govern your use of the Muster service (the “Service”) by Meridien Media, LLC (“Muster” or “we” or “our” or “us”). Your use of the Service is conditioned on acceptance of these terms.

Your use of the Service is subject to our Privacy Policy, which may be amended, and the terms and conditions in other agreements between you and Muster, and applicable agreements with related third parties.

If you do not accept these Terms, or later retract your agreement, you agree to stop accessing or using the Service by any means and through any channel(s). Any rejection of these Terms in whole or in part voids all service agreements or reliance interests with respect to Muster.

In the event of a conflict between these Terms and other relevant contracts or policies, the conflict shall be resolved in favor of the terms that more specifically address the particular question in controversy.

We reserve the right to change these Terms, or privacy policy, and other terms and conditions. When we make changes, we will ask you to accept or reject the changes. If you do not accept the changes, you agree that we may discontinue your access to the site and the Service. You agree that any such discontinuation will be without harm or prejudice to you. This Agreement or its latest version is in effect when you accept it, and remains in effect for so long as you access, use, or in any way use the Service. In all cases, your continued use is subject to these Terms’s terms.

All use of the Service is subject to these Terms, including this “Use Policy.” There may be penalties for violating the Use Policy up to the termination of your access to the Service, termination of your account, and legal action. Each term of the Use Policy expressly also applies to the use of the Service by your Users.

The Service may only be used for lawful purposes. You cannot post, transmit, promote, distribute, store, or otherwise use the Service or any content that could subject you or us to any liability. You may not use the Service in any way that would violate any law or regulation, including laws that govern the distribution of e-mail.

Prohibited conduct includes advertising or promoting any illegal activity; using false statements to obtain, or attempt to obtain, account information or other private information from other persons, including other Service users; and posting content that defames, abuses, or threatens harm to another person.

The determination of whether your conduct or content is objectionable or problematic shall be made by Muster, in its discretion. Examples of conduct or content that violates these terms include, but are not limited to, the uploading, input, or distribution of any material or communications that are pornographic, vulgar, or otherwise obscene; content or conduct that is racially or ethnically offensive; and harassing, abusing, threatening, or stalking any other person, whether or not such conduct constitutes a crime or is subject to civil liability.

The complete list and descriptions for all services offered is posted on Muster’s website ( We reserve the right to modify our services from time to time.

Identification of Muster

Muster has the right to insert its name, an image, and/or a link at the bottom of each e-mail, webpage, or other communication or medium related to the Service. We may also include a tagline or other short statement indicating that Muster provides the services that distributed a given communication (e.g., “Powered by Muster”), or a Muster logo.

You agree not to use information, materials, or other content that are protected by copyright, trademark, trade secret, non-disclosure or confidentiality agreements, or other intellectual property protections without the express written consent of the owner.


You may send bulk e-mail, text messages, and faxes, but you may not send unsolicited communications (“spam”) by these means or any other means, to any recipient that has not affirmatively opted-in to receiving such communications from you. In addition to the requirements and limitations of these Terms, you must comply with all applicable laws and regulations governing the transmission of e-mail, including but not limited to the federal Controlling the Assault of Non-Solicited Pornography and Marketing Act (CAN-SPAM Act) and Telephone Consumer Protection Act (TCPA).

You must maintain a record of your consent to use and messaging opt-in for each e-mail address and telephone number that you or your Users enter into the Service. You must provide all such Audit Information requested by Muster within ten (10) calendar days from the date of Muster’s request.

We reserve the right at all times to limit or terminate your access to messaging functions of the Service, temporarily or permanently, in response to complaints or if we observe a volume of messaging activity that suggests a lack of such compliance or that might lead to deliverability problems for you, for us, or for any other users of the Service.

You cannot use the Service, software, or hardware in a way that compromises the security of the Service or unreasonably disrupts the normal use or operation of the Service.

You agree to protect all usernames, passwords, and all other login or access information usable to access any part of the Service using a high degree of diligence and care. You cannot allow any person other than your employees or other authorized agents to view or access password-areas of the Service. You must immediately notify Muster if you believe that any password or other access data may have been compromised or that the Service has become otherwise available to unauthorized third parties.

Anyone with whom you share you log-in information will be considered by us to be authorized to use your Account and the Services. You agree to inform all such users of your account that they are bound by these terms. Muster accepts no responsibility or liability of any kind for any unauthorized access or use of your Account, and all such unauthorized use will be at client’s sole risk and liability.

Only those users and authorized representatives according to the account management data provided by you are entitled to contact Muster for customer support.

Anti Spam Policy

We take anti-spam seriously. Spam generated by one client can have a negative impact on all, so it is important that your emails remain compliant.
As stated earlier in our Terms of Service, spam is prohibited. Below are the limits we use to determine whether an email is compliant. By sending an email, you are agreeing to abide by these limits.

     Email Limits
     Hard bounces = 5% (1 in 20)
     Unsubscribes = 5% (1 in 20)
     Spam reports = 0.1% (1 in 1,000)

Exceeding any of these limits may result in the immediate suspension of your email delivery. Any direct complaints to our support specialists may also result in the immediate suspension of your email delivery.

Audit Right

In the event of a request by one of your contacts, one of our technical services vendors, a government agency, contract partner, or from Muster itself, Muster may require, and you agree to provide within ten (10) business days of Muster’s request, records of all opt-in, opt-out, unsubscribe, or other related contact preference communications and records related each of your contacts.

Marks and Intellectual Property

You acknowledge that Muster is the sole owner of its trademarks and brand assets, and that other marks are the property of their respective owners. You agree that you will not use any mark, photo, image, logo, textual work, icons, software, or other privately owned asset or intangible property (“Work”) for any purpose without the prior express written consent of its owner. Muster grants its users a non-exclusive, limited, right to use and access its software as necessary to use the Service. All other rights in copyright and other intellectual property rights, including but not limited to any Work are reserved, and are the property of Muster or its licensors.


For our pricing, please see our offerings, service levels, and pricing at our plans and pricing page: If you opt to include add-on services for which we coordinate with third parties, you will be responsible to pay such fees as part of the overall cost of your services. We will disclose to you the best pricing information we have from such third parties, but you agree that we do not control third-party pricing. You understand and agree that prices are subject to change.


You agree to use at a high degree of diligence and care to protect Muster’s non-public information obtained pursuant to or as a result of your use of the Service. You may not use, disseminate, or disclose our non-public information or that of any other user of the Service, to any third-party, for any purpose other than performing the obligations or receiving the benefits of the Service, or as required by law, permitted by these Terms.

Muster’s non-public information and all of its intellectual property will remain the sole property of Muster regardless of your access, use, and/or knowledge of any of it.

Content You Upload and Use

You represent and agree, on behalf of yourself and all other users of your account, that you have and will continue to have rights to upload, use, copy, and distribute any and all content that you upload, use, copy, and distribute in connection with the Service.

We will back up the data that you have stored on the Service on a regular basis. Although we make every effort to ensure your data will be available for restoration, we do not guarantee it. It is your responsibility to back up your own data to ensure recoverability.

Delivery of messages

Muster enables communication(s) to legislative, member lists, and other targets of online advocacy via e-mail, text messaging, USPS mail, twitter, patch-through phone calls, and fax. While messages will most often be delivered immediately, we reserve the right to delay, throttle, or send in batch format. In rare cases, faxes may be sent when all e-mail attempts have failed.

Muster reserves the right to only attempt to send direct constituent communications; messages from advocates outside an elected official district may not be processed.

Muster may dedupe multiple advocate submissions within short time frames, within the same campaign, or not send duplicate messages. 

Muster reserves the right to drop a delivery when all required information is not present content.

Muster reserves the right to halt advocate messages not from real people, in the real world. Suspension of your service will occur if Muster has evidence of such activity.


We may integrate with third party data, messaging, hosting, and other cloud-based services. Some of these integrations will be invisible to you, while others may require you to establish and maintain your own accounts with these providers, and your acceptance of those independent services, costs, and terms of service will be a condition of your use of any functions of the Service that are related to such integration partners. We have no control over nor responsibility for the terms, costs, functions, or relationships with such other providers. Our integrated functions with these third parties may change over time, but may include such functions such as calendars and scheduling, messaging, web hosting, location data services, payment processing, streaming media, financial reporting, third-party logins, social media posts, advertising networks, and other functions relating to the Service and your business. By using the Service, you authorize the connection between Muster and each such third party, as well as the sharing of data with each such third-party integration partner, and you accept the risk associated with the transmission and sharing of data and software connections with each such integration partner. You agree to authorize within Muster and/or each third-party app or web site the data connections that are necessary, and to re-authorize such data connections from time to time as prompted by Muster or any integration partner.

Export Regulations

You warrant that you will comply with all domestic and international export laws, regulations, and other controls that apply to the distribution, development, users, and use of the Service, including the U.S Department of Commerce’s Export Administration Regulations, programs of the U.S. Treasury Department’s Office of Foreign Assets Control, and all other applicable laws, regulations, and protocols.

It is your responsibility to know and to follow the rules in the countries in which you operate and to which you direct your activities and into which you send any form of communication through the Service.

Enforcement by Muster

Muster may enforce these Terms at our discretion, and we reserve the right to make the determination with that discretion as to whether your conduct or content violates these Terms or otherwise places undue burdens on the Service or other users, or creates excessive risk for Muster. Our failure to enforce these Terms shall not constitute a waiver of any conduct by you or any others that precedes such failure. Our election of a remedy or remedies does not require the exclusion of any other remedies.

We may immediately take any or all of the following enforcement actions:

Suspend Access. Muster may suspend your access to and operation of the Service, except that in the case of a failure to comply with the Payment Terms, Muster has the option to either

Impose late fees or other fees pursuant to our pricing policies, or to compensate Muster for costs of any non-compliance with these Terms or other harmful behaviors by you

Suspend your access to and operation of the Service
