Terms of Service

Last updated: 06/16/2026

These Terms of Service ("Terms") govern your access to and use of the Signilio platform, including our website, application, APIs, and related services (the "Services"), operated by Signilio LLC ("Signilio," "we," "us," or "our"). By creating an account or using the Services, you confirm that you are at least 18 years old, that you have authority to bind your business to these Terms, and that you agree to them. If you do not agree, do not use the Services.

Authority to bind

If you accept these Terms or use the Services on behalf of a business or other entity, you represent and warrant that you have the authority to bind that entity, and "you" refers to both you and that entity. If you do not have that authority, you must not accept these Terms or use the Services, and if you do, you accept these Terms in your individual capacity and are personally responsible for all obligations under them, including all fees, charges, fines, and indemnification obligations.

Your account

You are responsible for all activity under your account. Keep your credentials secure and do not share access with unauthorized people.

  • Provide accurate registration information and keep it current
  • You are responsible for ensuring any users you grant access comply with these Terms
  • Notify us immediately at admin@signilio.com if you believe your account is compromised

Acceptable use

Signilio is a platform for legitimate, consent-based business messaging. Your use is governed by our Acceptable Use Policy and Messaging Compliance Policy, which are incorporated into these Terms by reference. In summary, you must only message recipients who have consented, honor opt-outs immediately, identify yourself accurately, comply with the TCPA, CAN-SPAM, CTIA guidelines, A2P 10DLC requirements, and all applicable laws, and not send prohibited content. Violations are grounds for suspension or termination.

Consent and recipient data

You represent and warrant that every recipient you message through the Services has provided valid consent to receive your communications as required by applicable law, and that you maintain verifiable proof of that consent (including the date, time, method, and content of opt-in) and will provide it to us upon request. You are solely responsible for the lawfulness of your messaging and for your relationship with your contacts. Signilio acts as a technical platform; we do not originate your messages or independently verify your consent records.

You are the sender; Signilio is a conduit

Signilio provides the technical platform that transmits messages you create and send. You — not Signilio — are the sender and originator of all messages sent through your account. You determine the recipients, the content, the timing, and the basis on which each recipient is contacted. You are solely responsible for compliance with all applicable laws governing your messages, including the Telephone Consumer Protection Act (TCPA), CAN-SPAM, state messaging laws, CTIA guidelines, and carrier requirements, and for maintaining and producing valid proof of consent for every recipient. Signilio does not originate your messages, does not control your recipient lists or content, and does not independently verify your consent. You agree that any liability arising from messages sent through your account rests with you, and you will indemnify Signilio for any claim arising from your messages or your failure to comply with applicable law, as set out in the Indemnification section.

A2P 10DLC and business registration

Business SMS sent over 10-digit long codes in the US must be registered with The Campaign Registry through carrier channels. This is a CTIA and carrier requirement, not a Signilio policy. When you submit information for brand or campaign registration — including business legal name, EIN, website, and use-case details — you represent and warrant that all such information is accurate, truthful, and that you are authorized to submit it. Signilio facilitates submission to upstream providers and carriers but does not independently verify EIN ownership or business identity, and relies on the information you provide.

You acknowledge that inaccurate or unauthorized registration information may result in campaign rejection, brand suspension, carrier blocking, or penalties, and that Signilio is not liable for any such consequences. You agree to indemnify and hold Signilio harmless from any claims, penalties, or losses arising from inaccurate, fraudulent, or unauthorized registration information you submit. We may request documentation verifying your business or EIN at any time and may suspend messaging until it is provided.

Vetting and high-risk use

We may review any account, brand, campaign, or message traffic at any time. We may require additional vetting for, restrict, suspend, or terminate any sender or use case that we determine — in our sole discretion — presents legal, regulatory, carrier, or reputational risk, or that generates elevated complaint or filtering rates. Approval of an account or campaign is not a determination that your messaging is lawful; that responsibility remains yours.

Billing

How billing works. The Services are billed on a usage basis. Each message segment you send is charged at the rate published on our pricing page (a segment is 160 characters; longer messages use multiple segments). If your account uses a prepaid balance, charges are deducted from that balance as messages are sent; you are responsible for maintaining sufficient funds. Phone numbers and 10DLC campaign registrations carry recurring monthly fees, passed through at cost, billed in advance and continuing until cancelled. You authorize us to charge your payment method on file for all amounts due, including recurring fees and applicable taxes. We will make pricing available on our website and provide notice of changes as required by law.

The Services are billed on a usage basis at the pricing then published or otherwise agreed in writing.

  • Usage charges. You are charged per message sent through the Services at the applicable rate.
  • Prepaid balance. Your account may operate on a prepaid balance ("wallet"). You add funds, and message and related charges are deducted as incurred. It is your responsibility to maintain a sufficient balance; the Services may be unable to send messages if your balance is insufficient.
  • Passthrough costs. Phone number provisioning and 10DLC registration are billed as passthrough costs at what we are charged by carriers or the registry. These are compliance/infrastructure costs, not platform fees, and are subject to change by those third parties.
  • Payment. You authorize us to charge your payment method on file for amounts due, including applicable taxes. Prices may change; we will provide notice as required by law.
  • Failed or insufficient payment. We may suspend the Services for unpaid balances. Persistent non-payment may result in termination and referral to collections.

Recurring fees and auto-renewal. Phone number and 10DLC campaign fees are recurring monthly charges that automatically renew each billing period until you cancel the associated number or campaign. You may cancel a recurring item at any time through your account or by contacting admin@signilio.com; cancellation takes effect at the end of the current billing period, and the current period's fee is non-refundable. We do not charge a separate platform subscription fee.

Carrier fines, penalties, and surcharges

Wireless carriers and upstream providers may assess fines, penalties, surcharges, or other charges in connection with messaging traffic — including, without limitation, charges for violations of carrier rules, A2P 10DLC requirements, opt-in/opt-out obligations, prohibited content, or unregistered or non-compliant traffic. You are solely responsible for any such fine, penalty, surcharge, or charge that arises from or is attributable to your messaging, your content, your recipients, or your compliance failures. You authorize us to charge these amounts to your payment method or prepaid balance, or to invoice you for them, and you agree to pay them in full. These charges are assessed by third parties, may be imposed after the underlying messages are sent, are subject to change, and are non-refundable. This obligation is in addition to, and does not limit, your indemnification obligations under these Terms.

Refunds

Amounts spent on messages already processed and submitted for delivery are non-refundable. Passthrough costs (numbers, 10DLC registration) are non-refundable, as they represent amounts paid to third parties. Prepaid balances are non-refundable except where required by law.

No chargebacks; financial responsibility

Charges for delivered messages and provisioned services are final. By using the Services, you agree:

  • You will not initiate a chargeback or payment dispute for any successfully processed and fulfilled transaction.
  • If you believe a charge is in error, you will first contact us at admin@signilio.com to resolve it in good faith before pursuing any external dispute.

Initiating a chargeback in violation of this section is a material breach of these Terms. We may immediately suspend or terminate your account, and you agree to be financially responsible for: the full original transaction amount; any chargeback or administrative fees we incur; all reasonable legal, court, and collection costs we incur to enforce this provision; and any additional losses caused by the dispute. This provision protects against abuse and reflects that message charges fund real, immediately-incurred third-party delivery costs.

Intellectual property

The Services — including all software, design, features, and branding — are owned by Signilio. These Terms grant you a limited, non-exclusive, non-transferable, revocable license to use the Services while your account is active and in compliance. You own the content of the messages you send and the data in your account, and you grant us a limited license to process, store, and transmit that content as necessary to provide the Services. We may use aggregated, de-identified usage data to improve the Services; such data does not identify you or your message content.

Termination

By you: You may close your account at any time. You remain responsible for charges incurred before closure. Data handling follows our Privacy Policy.

By us: We may suspend or terminate your account for violation of these Terms or our policies, non-payment, carrier termination of your traffic, fraud or misrepresentation, any activity that endangers the deliverability or reputation of the platform or other senders, or legal requirement. For non-egregious first-time issues we will typically give you an opportunity to remediate; serious violations (including prohibited content, ignoring opt-outs, or fraud) may result in immediate termination without notice. Prepaid amounts are non-refundable on termination for cause.

Disclaimers

THE SERVICES ARE PROVIDED "AS IS" AND "AS AVAILABLE." WE MAKE NO WARRANTIES, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. We do not warrant uninterrupted or error-free operation, specific delivery rates, or specific results. SMS delivery depends on carriers and is subject to carrier decisions, filtering, and policy changes outside our control.

Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, SIGNILIO'S TOTAL LIABILITY FOR ANY CLAIM ARISING OUT OF OR RELATING TO THESE TERMS OR THE SERVICES SHALL NOT EXCEED THE AMOUNT YOU PAID US IN THE THREE (3) MONTHS PRECEDING THE CLAIM. IN NO EVENT SHALL WE BE LIABLE FOR INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL, OR PUNITIVE DAMAGES, INCLUDING LOSS OF PROFITS, REVENUE, OR DATA.

Indemnification

You agree to defend, indemnify, and hold harmless Signilio and its officers, employees, and agents from any claims, damages, losses, liabilities, and expenses (including reasonable attorneys' fees) arising from: your use of the Services; your messages or content; your violation of these Terms or applicable law; your consent or registration representations; or your violation of any third party's rights.

Governing law and disputes

These Terms are governed by the laws of the State of Wyoming, without regard to conflict-of-law principles. The parties will first attempt to resolve any dispute informally for at least thirty (30) days after written notice. If unresolved, disputes will be settled by binding arbitration on an individual basis under the rules of the American Arbitration Association. You and Signilio waive any right to a jury trial and to participate in a class action. Claims seeking to protect intellectual property and requests for injunctive relief are excepted and may be brought in the state or federal courts located in Wyoming.

Changes

We may update these Terms. We will provide notice of material changes as required by law. Continued use after the effective date constitutes acceptance.
