These Terms of Service ("Terms") govern access to and use of the AntiSpamSMS website at antispamsms.com and related SMS platform services (collectively, the "Services"). By accessing the site or using the Services, you agree to these Terms. If you are entering into these Terms on behalf of a company, you represent that you have authority to bind that company.
AntiSpamSMS provides USA-focused SMS capabilities that may include bulk messaging, OTP verification, two-way messaging, APIs, anti-spam tooling, and marketing campaign features. Features available to you depend on your plan, configuration, and any order or quote accepted by email. We may update features over time to improve deliverability, security, or compliance support.
You must be at least 18 years old and able to form a binding contract under applicable United States law. You are responsible for maintaining the confidentiality of account credentials and for all activity under your account. Notify us promptly at hello@antispamsms.com if you suspect unauthorized access.
You agree to use the Services only for lawful, consented messaging. Without limitation, you must not:
We may suspend or terminate traffic that creates elevated spam complaints, carrier filtering risk, or legal exposure.
You are solely responsible for the content of messages you send and for compliance with applicable laws and industry guidelines, including but not limited to the Telephone Consumer Protection Act (TCPA), CAN-SPAM where relevant to related email, state privacy laws, carrier codes of conduct, and campaign registration requirements associated with A2P/10DLC programs. AntiSpamSMS may provide educational guidance and tooling, but such materials are not legal advice.
You must honor opt-out requests promptly, include required disclosures for marketing traffic, and maintain records of consent. You agree not to send marketing content labeled or routed as purely transactional OTP or alert traffic.
You retain ownership of message content, contact lists, and other materials you submit ("Customer Content"). You grant AntiSpamSMS a limited license to host, process, transmit, and display Customer Content solely to provide and improve the Services, prevent abuse, and comply with law. You represent that you have all rights necessary to submit Customer Content and to message the phone numbers you upload.
Fees are described in your quote, order form, or account plan. Usage-based charges (for example, per-message fees) may apply based on volume, destination, and message type. Unless otherwise stated, fees are in U.S. dollars and exclusive of taxes. You are responsible for applicable taxes other than taxes based on our net income. Late unpaid amounts may result in suspension.
We may modify or discontinue features with reasonable notice when practical. Beta or preview features are provided as-is and may be changed or withdrawn at any time.
SMS delivery depends on telecommunications carriers and intermediaries outside our exclusive control. Delivery times and success rates can vary. We do not guarantee that every message will be accepted by every handset or carrier.
Each party may receive non-public information from the other. The receiving party will use reasonable care to protect such information and use it only for performing under these Terms, except where disclosure is required by law.
AntiSpamSMS and its licensors own the platform, branding, documentation, and site content (excluding Customer Content). These Terms do not transfer ownership of our intellectual property. You may not copy, reverse engineer, or resell the Services except as expressly permitted in writing.
Our collection and use of personal information is described in the Privacy Policy at privacy.html. By using the Services, you acknowledge that policy.
THE SERVICES ARE PROVIDED "AS IS" AND "AS AVAILABLE." TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE DISCLAIM WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. WE DO NOT WARRANT UNINTERRUPTED OR ERROR-FREE OPERATION OR THAT THE SERVICES WILL MEET ALL OF YOUR COMPLIANCE OBLIGATIONS WITHOUT YOUR OWN POLICIES AND CONTROLS.
TO THE MAXIMUM EXTENT PERMITTED BY LAW, ANTISPAMSMS WILL NOT BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, REVENUE, DATA, OR GOODWILL. OUR AGGREGATE LIABILITY ARISING OUT OF THESE TERMS WILL NOT EXCEED THE AMOUNTS PAID BY YOU TO ANTISPAMSMS FOR THE SERVICES IN THE TWELVE (12) MONTHS BEFORE THE CLAIM.
You will defend and indemnify AntiSpamSMS against claims arising from your Customer Content, messaging practices, alleged lack of consent, or violation of these Terms or applicable law.
You may stop using the Services at any time. We may suspend or terminate access for non-payment, abuse, legal risk, or material breach. Upon termination, your right to use the Services ends, though provisions that by nature should survive (including fees owed, IP, disclaimers, and limitations) will survive.
You represent that you are not prohibited from receiving services under U.S. export control or sanctions laws and will not use the Services in violation of those laws.
These Terms are governed by the laws of the United States and the State of Delaware, without regard to conflict-of-law principles, except where mandatory consumer protections apply. Courts located in the United States will have exclusive jurisdiction, subject to applicable law.
We may update these Terms by posting a revised version on this page and updating the "Last updated" date. Continued use after changes become effective constitutes acceptance of the revised Terms.
Questions about these Terms may be sent to hello@antispamsms.com. We do not publish telephone numbers or physical mailing addresses on this site.
