By accessing or using the SigSpan platform ("Service"), operated by Infrastructure and Integration Group (IIG), you agree to be bound by these Terms of Service ("Terms"). If you do not agree to these Terms, do not use the Service.
SigSpan provides an email-to-text (email-to-SMS) bridge platform that converts incoming email alerts into text message (SMS) notifications delivered to designated phone numbers. The Service is designed exclusively for transactional, non-promotional business communications such as IT system alerts, server and infrastructure monitoring notifications, and on-call team alerting. The Service is not intended or permitted for marketing, promotional, advertising, affiliate marketing, lead generation, or other solicitation messaging, and any such use is prohibited.
To use the Service, you must create an account. You agree to:
New accounts receive a 15-day free trial with full access to all platform features. The trial includes up to 25 text messages, 5 phone numbers and 2 recipient groups. No credit card is required to start a trial. A trial does not convert to a paid account automatically: to continue sending alerts after the trial, you must add a payment method or be approved for invoice billing. Trial extensions may be requested by contacting us at admin@sigspan.com.
SigSpan uses tiered, pay-as-you-go pricing with no monthly platform fees:
You are billed monthly, after the end of each billing period, for the SMS messages actually sent during that period.
Automatic payment. Unless your account has been approved for invoice billing, you pay by credit or debit card or by US bank account (ACH debit). The payment method on file is charged automatically for each billing period. You can change your payment method at any time from your account.
Invoice billing. Business customers may request invoice billing, which we approve at our discretion. Approved accounts receive an invoice by email each month, and payment is due within the payment terms shown on the invoice. Invoices can be paid online by card or US bank account, or by bank transfer using the details on the invoice. If your organization requires a purchase order, you are responsible for giving us a current purchase order number; we will reference it on your invoices.
Late or failed payment. If an automatic payment fails or an invoice is not paid by its due date, we will notify you by email and alert delivery continues for 14 days. If the balance is still unpaid after 14 days, alert delivery is paused until it is paid. You remain responsible for charges for messages already sent.
Usage limits. You can limit how many alerts are texted per hour or per day, and how many identical alerts are texted within a set time, from your account. Alerts held back by these settings are not texted and are not billed. You are responsible for choosing settings that suit your needs, including the risk that an alert held back by your settings is not delivered.
You agree to use the Service only for lawful purposes. You may not:
Program description. SigSpan delivers transactional, service-related text messages (SMS) - IT system alerts, server and infrastructure monitoring notifications, and on-call team alerts - that originate from the systems you connect to the Service. SigSpan does not send marketing, promotional, advertising, affiliate marketing, or lead-generation messages, and such use is prohibited.
Message frequency. Message frequency varies and depends on the volume of alerts generated by your connected systems. Message and data rates may apply.
Opt-out and help. Recipients may opt out at any time by replying STOP; no further messages will be sent to that number. Reply HELP for assistance, or contact admin@sigspan.com. SigSpan automatically processes STOP and opt-out requests, and messages will not be delivered to numbers that have opted out. Mobile carriers are not liable for delayed or undelivered messages.
Your TCPA responsibilities. SigSpan provides tools to support compliance with the Telephone Consumer Protection Act (TCPA), but you are responsible for:
Recipient phone numbers and SMS opt-in and consent data are used solely to deliver the Service and are never shared with third parties or affiliates for marketing or promotional purposes. See our Privacy Policy for details.
We strive to maintain high availability of the Service but do not guarantee uninterrupted access. The Service may be temporarily unavailable due to maintenance, updates, or circumstances beyond our control. We will make reasonable efforts to provide advance notice of planned downtime. The Service is intended as a supplementary alerting mechanism and should not be relied upon as the sole means of monitoring critical infrastructure or systems.
Your use of the Service is also governed by our Privacy Policy, which describes how we collect, use, and protect your data. By using the Service, you consent to the data practices described in the Privacy Policy.
The Service, including its design, features, and documentation, is the property of Infrastructure and Integration Group (IIG). You retain ownership of the content you transmit through the Service. You grant us a limited license to process your content solely for the purpose of providing the Service.
To the maximum extent permitted by law, SigSpan and IIG shall not be liable for any indirect, incidental, special, consequential, or punitive damages, including but not limited to loss of profits, data, or business opportunities, or damages resulting from missed, delayed, or undelivered alert notifications, even if SigSpan has been advised of the possibility of such damages, arising from your use of the Service. Our total aggregate liability shall not exceed the greater of: (a) the total fees paid by Customer in the three (3) months immediately preceding the claim, or (b) five hundred dollars ($500.00).
You agree to indemnify and hold harmless SigSpan, IIG, and their officers, employees, and agents from any claims, damages, or expenses arising from your use of the Service, your violation of these Terms, or your violation of any applicable law or regulation, including TCPA.
You may stop using the Service at any time. Since there are no monthly fees or contracts, you will only be billed for messages already sent, including on a final bill or invoice after you stop. We may suspend or terminate your access to the Service if you violate these Terms or engage in activity that harms the Service or other users. We will provide reasonable notice before termination unless immediate action is required to prevent harm.
We may update these Terms from time to time. We will notify you of material changes by posting the updated Terms on this page with a revised "Last updated" date. Continued use of the Service after changes constitutes acceptance of the updated Terms.
These Terms are governed by the laws of the State of Colorado. Any dispute that cannot be resolved through good-faith negotiation within thirty (30) days shall be submitted to binding arbitration administered by JAMS under its Streamlined Arbitration Rules, with proceedings conducted in Archuleta County, Colorado. You and IIG waive the right to a jury trial and to participate in any class action proceeding.
