This provision establishes a unilateral amendment mechanism under which Twilio can modify agreement terms with 30 days notice, and the customer's continued use of services constitutes binding acceptance of those modifications. The carve-out for law, regulation, or telecommunications provider-driven changes permits immediate or shorter-notice modifications in those circumstances.
Interpretive note: The enforceability of continued-use acceptance for material contractual changes varies by jurisdiction, particularly in the EU where unfair contract terms frameworks and GDPR consent requirements may constrain how changes to data processing terms take effect.
The updated terms establish a binding arbitration requirement for users domiciled or registered in Mexico, replacing prior dispute resolution procedures. Under the revised Section 10.5, Mexico-domiciled users must first engage in good faith negotiations with Segment for up to 30 days, and if unresolved, disputes proceed to binding arbitration administered by the Centro de Arbitraje de México (CAM) in Mexico City before a sole arbitrator, with both parties splitting arbitration costs. Additionally, the agreement now explicitly carves out Mexico's Federal Consumer Protection Law (Ley Federal de Protección al Consumidor), stating it does not apply to this commercial agreement. Mexico users also face a new obligation to comply with anti-money laundering and anti-corruption requirements under applicable Mexican law.
View change record →Segment's updated terms now apply Japan-specific dispute resolution, verification, and tax requirements to customers domiciled or registered in Japan. The agreement now states that arbitration proceedings for Japanese customers will take place in Mexico City, Japan (implied Tokyo venue under the new Japan section), conducted in English. Japanese customers may be required to submit government-issued ID documents and complete verification processes as required under applicable Japanese law, including the Act on Prevention of Transfer of Criminal Proceeds and the Telecommunications Business Act. All fees are payable in Japanese Yen, and taxes will include Japanese consumption tax. Intellectual property rights now incorporate Japanese Copyright Act provisions. You can review the specific verification requirements by contacting Segment or reviewing the applicable service section.

"Twilio may update the terms of this Agreement from time to time. Twilio will provide you with written notice of any material updates at least thirty (30) days prior to the date the updated version of this Agreement is effective, unless such material updates result from changes in laws, regulations, or requirements from telecommunications providers. The current, up to date version of this Agreement will be available at https://www.twilio.com/legal/tos . Notices for material updates to the terms of this Agreement will be given in accordance with Section 9.5 (Notices). Following such notice, your continued use of the Services on or after the date the updated version of this Agreement is effective and binding, as indicated at the top of this Agreement, constitutes your acceptance of the updated version of this Agreement. The updated version of this Agreement supersedes all prior versions. If you do not agree to the updated version of this Agreement, you must stop using the Services immediately.Excerpt from Segment's Terms of Service
REGULATORY LANDSCAPE: Unilateral amendment clauses governed by continued-use acceptance are common in commercial SaaS agreements and are generally enforceable in US jurisdictions when adequate notice is provided. In the EU, such clauses may be subject to scrutiny under unfair contract terms frameworks, particularly where changes materially alter the economic balance of the agreement. The 30-day notice period, with exceptions for regulatory and carrier-driven changes, may or may not satisfy notice adequacy standards in specific jurisdictions. GOVERNANCE EXPOSURE: Medium. The exception for telecommunications provider-driven changes permits Twilio to modify material terms without the standard 30-day notice period. For customers whose operations depend on specific service configurations or pricing structures, this creates uncertainty about the scope of changes that may take effect on short notice. JURISDICTION FLAGS: EU customers should evaluate whether the continued-use acceptance mechanism satisfies GDPR consent requirements for any data processing changes introduced through agreement updates, as GDPR requires freely given, specific, informed, and unambiguous consent for data processing that cannot be implied from continued commercial use. UK customers should evaluate the same consideration under UK GDPR. CONTRACT AND VENDOR IMPLICATIONS: Procurement teams should establish internal processes to monitor the Twilio legal terms page and evaluate material updates before their effective dates. The 30-day notice window provides a limited but defined period to assess and respond to changes before they become binding. COMPLIANCE CONSIDERATIONS: Legal and compliance teams should implement a systematic review process for Twilio agreement updates, particularly for changes driven by telecommunications provider requirements that may take effect without the standard 30-day notice period. Data processing changes introduced through agreement updates may require evaluation against GDPR or CCPA obligations.
