To use certain Services, you must create an Abelo account and provide accurate, complete and current information.

  • obtaining and maintaining all required consents and permissions;

  • maintaining appropriate records of consent where required;

  • ensuring that your campaigns and communications comply with applicable laws;

  • ensuring that your use of integrations and customer data is lawful.


Abelo provides the technology and infrastructure through which you send communications. Unless expressly agreed otherwise, you remain responsible for the substance, legality and purpose of those communications.


Additional requirements relating to prohibited content, consent, spam, messaging practices and technical abuse are set out in the Abelo AUP.


6. Customer and End-User Data


6.1 Your Data


For purposes of these Terms, "Customer Data" means information, content, personal data, customer records, product information, order information, campaign content and other data that you upload, transmit, synchronize or otherwise make available to Abelo through your use of the Services.


As between you and Abelo, you retain your rights in Customer Data.


You grant Abelo a limited, non-exclusive right to host, store, reproduce, transmit, process and otherwise use Customer Data solely as necessary to provide, maintain and secure the Services, comply with your documented instructions, and comply with applicable law. Where Abelo processes personal data on your behalf as a data processor, such processing is subject to the applicable Data Processing Agreement. Abelo may use aggregated or anonymized information that does not identify you or any individual to analyze, improve and develop the Services.


6.2 End-Customer Data


Where you use Abelo to process personal data relating to your customers, users or other recipients, you are responsible for ensuring that you have an appropriate legal basis and all required permissions for collecting and processing that data and for instructing Abelo to process it.


Where applicable, Abelo processes such personal data on your behalf as a data processor and only in accordance with your documented instructions, subject to the applicable Data Processing Agreement and applicable law.


Our Privacy Policy explains how Abelo processes personal data and distinguishes between situations where Abelo acts as a controller and situations where Abelo acts as a processor.


6.3 Data Accuracy


You are responsible for the accuracy, quality and legality of Customer Data that you upload or synchronize with Abelo.


You must not upload or synchronize data that you are not legally entitled to process or provide to Abelo.


6.4 Third-Party Integrations


Where you connect Abelo to Shopify, WooCommerce, or another supported third-party service, you authorize Abelo to access and process the information made available through that integration for the purpose of providing the Services.


Your use of third-party services remains subject to the relevant third party's terms and policies.

7. Messaging Channels and Third-Party Providers


Abelo relies on third-party messaging networks, telecommunications operators, technology providers and channel providers to deliver certain communications.


Depending on the channel and service configuration, these may include Viber, SMS carriers, WhatsApp and other messaging or infrastructure providers.

Message delivery may depend on factors outside Abelo's control, including:


  • recipient device availability;

  • network connectivity;

  • telecommunications operators;

  • channel policies;

  • recipient account status;

  • spam or fraud controls;

  • content restrictions;

  • sender verification;

  • delivery windows or validity periods; and

  • technical failures affecting third-party infrastructure.


Accordingly, Abelo does not guarantee that every message will be delivered, seen, clicked or otherwise received by its intended recipient.


Where SMS fallback or another fallback mechanism is enabled, the fallback service remains subject to the applicable channel availability, configuration and fees. Where SMS fallback is enabled by the Customer, any message that cannot be delivered through the primary messaging channel (such as Viber) and is subsequently routed via SMS will be billed at the applicable SMS rates set out in the Customer's rate card. The Customer is solely responsible for configuring and managing fallback rules to monitor and control its messaging expenditure.


8. API and Developer Services


Where Abelo provides APIs, SDKs, webhooks or other developer functionality, you must use them in accordance with the applicable technical documentation, rate limits and security requirements.


You must not:

  • expose private API credentials publicly;

  • use API credentials in unauthorized client-side applications;

  • circumvent rate limits or security controls;

  • attempt to gain unauthorized access to Abelo systems;

  • interfere with the operation of the APIs;

  • reverse engineer the Services except where expressly permitted by applicable law; or

  • use the APIs to create a competing service based on Abelo's proprietary technology, except where expressly authorized.


We may impose or modify reasonable technical limits, rate limits or usage restrictions to protect the Platform and its users.


9. Subscription Plans, Fees and Credits


9.1 Subscription


Access to certain Abelo Services requires an active subscription or commercial agreement.


Your subscription plan determines the features, usage limits, included credits and other conditions applicable to your account.


9.2 Messaging and Usage Charges


Certain Services may be charged based on messaging volume, credits, orders, usage, subscription level or other metrics specified in your applicable pricing plan or commercial agreement.


Applicable prices are those displayed in your Abelo account, stated in an order or commercial agreement, or otherwise communicated to you by Abelo.


9.3 Credits and Prepaid Balance


Where Abelo utilizes prepaid credits or a wallet balance, the Customer must maintain an adequate balance in its account to dispatch communications.


Prepaid credits and wallet balances may be used solely for the Services and purposes authorized by Abelo. Unless expressly agreed otherwise in a written commercial agreement, prepaid wallet balances and unused credits are non-transferable, have no cash redemption value, and are non-refundable upon voluntary termination or cancellation by the Customer, but remain available for messaging use through the effective termination date.


9.4 Taxes and Invoicing


Fees are exclusive of applicable value-added tax (VAT) and other statutory charges unless expressly stated otherwise.


You are responsible for paying all applicable VAT, sales taxes, or other governmental assessments associated with your use of the Services. Customers established in Greece or the European Union must provide accurate and complete corporate billing information, including company legal name, business activity, VAT identification number (ΑΦΜ), and competent Tax Office (ΔΟΥ), for the issuance of statutory electronic invoices in compliance with Greek tax legislation and the Independent Authority for Public Revenue (AADE / myDATA requirements).


9.5 Payment and Top-Ups


You agree to pay all amounts due in accordance with your subscription plan or commercial agreement.


Balance top-ups may be completed via bank wire transfer or other payment methods approved by Abelo. If any payment is overdue, we may suspend or restrict access to paid Services after providing reasonable notice where required by applicable law or your commercial agreement.


10. Changes to Pricing and Services


We may modify our pricing, plans, features or Services from time to time.


Where a change materially affects an existing paid subscription, we will provide reasonable advance notice where required.


Changes may take effect immediately where they are necessary to comply with applicable law, third-party channel requirements, security requirements, prevent fraud or abuse, or address technical or operational risks.


Your continued use of the Services following the effective date of a change constitutes acceptance of the revised terms, unless applicable law requires another form of acceptance.


11. Intellectual Property


11.1 Abelo Intellectual Property


The Platform, including its software, source code, object code, architecture, interfaces, APIs, documentation, designs, trademarks, logos, workflows, databases, features and other proprietary materials, is owned by or licensed to Trebbble S.A.


Except for the limited right to use the Services under these Terms, no intellectual property rights are transferred to you.


11.2 License to Use the Services


Subject to these Terms and your payment of applicable fees, Abelo grants you a limited, non-exclusive, non-transferable and revocable right to access and use the Services during the applicable subscription period.


You may not sublicense, resell, lease, distribute or otherwise commercially exploit the Platform unless expressly authorized by Abelo.


11.3 Feedback


If you provide suggestions, ideas or feedback regarding the Services, you grant Abelo the right to use that feedback without restriction or compensation, provided that such use does not disclose your Confidential Information.


12. Confidentiality


Each party may receive confidential information from the other party in connection with the Services.


The receiving party agrees to:


  • use Confidential Information only for purposes related to the business relationship;

  • protect it using reasonable measures; and

  • disclose it only to employees, contractors or professional advisers who need to know it and are subject to appropriate confidentiality obligations.


Confidential Information does not include information that:


  • is publicly available without breach of these Terms;

  • was already lawfully known to the receiving party;

  • is independently developed without use of the other party's Confidential Information; or

  • is lawfully received from a third party without confidentiality obligations.


A party may disclose Confidential Information where required by law, regulation or valid legal process, provided that it gives notice where legally permitted.


13. Availability and Service Changes


We aim to provide reliable and secure Services, but the Services are provided on an "as available" basis.


We do not guarantee uninterrupted or error-free operation.


The Services may occasionally be unavailable due to:


  • scheduled maintenance;

  • emergency maintenance;

  • telecommunications or internet failures;

  • third-party provider outages;

  • channel restrictions;

  • cyberattacks or security incidents;

  • force majeure events; or

  • other circumstances outside our reasonable control.


We may modify, update, suspend or discontinue features of the Services where reasonably necessary for operational, technical, legal, security or commercial reasons.

14. Suspension, Cancellation and Termination


14.1 Cancellation by the Customer


Subject to Section 14.2, any minimum commitment set out in an applicable commercial agreement, and any other service-specific terms agreed in writing, the Customer may terminate its use of the Abelo Platform at any time without any termination fee.


To terminate the Services at the end of a calendar month, and subject to any applicable minimum commitment, the Customer must provide Abelo with written notice at least five (5) calendar days before the end of that month.


For example, if the Customer wishes to terminate the Services effective 31 October, Abelo must receive the termination notice no later than 26 October.


If notice is received less than five (5) calendar days before the end of the month, termination will take effect at the end of the following calendar month, unless Abelo agrees otherwise in writing.


No early termination fee, cancellation fee, or other termination charge will apply solely as a result of the Customer terminating its use of the Abelo Platform.


Any fees or charges accrued up to the effective termination date remain payable.


14.2 Viber Business Messaging — Minimum Commitment and Termination


Notwithstanding Section 14.1, the minimum commitment for the Viber Business Messaging service is two (2) calendar months from the date on which the Viber service is activated for the Customer.


During the minimum two-month commitment period, the Customer may not terminate the Viber Business Messaging service with an effective termination date earlier than the end of the minimum commitment period, unless otherwise agreed in writing by Abelo.


Following completion of the minimum two-month commitment period, the Customer may terminate its use of Viber Business Messages at any time without any termination or cancellation fee.


To terminate the Viber Business Messaging service at the end of a calendar month, the Customer must provide Abelo with written notice at least five (5) calendar days before the end of that month.


For example, if the Customer's minimum commitment period has been completed and wishes to terminate Viber Business Messaging effective 31 October, Abelo must receive the termination notice no later than 26 October.


If notice is received less than five (5) calendar days before the end of the month, termination will take effect at the end of the following calendar month, unless Abelo agrees otherwise in writing.


No separate Viber termination fee, cancellation fee, or early termination fee will apply after completion of the minimum two-month commitment period.


Any fees or charges incurred up to the effective termination date remain payable.


Termination of Viber Business Messaging does not automatically terminate the Customer's other Abelo Services, unless the Customer expressly requests termination of the entire Abelo account or the applicable commercial agreement provides otherwise.


14.3 Effect of Cancellation


On the effective termination date:


  • the Customer's access to the terminated Services will cease;

  • the Customer will no longer be able to send messages through the terminated channel or Services;

  • any outstanding amounts incurred before the effective termination date remain payable; and

  • Customer Data will be handled in accordance with the Abelo Privacy Policy and, where applicable, the Data Processing Agreement.


Unless otherwise required by applicable law or expressly agreed in writing, fees already paid for a period before the effective termination date are non-refundable.


14.4 Suspension by Abelo


Abelo may suspend or restrict access to some or all of the Services where reasonably necessary, including if:


  • the Customer breaches these Terms or the Acceptable Use Policy;

  • the Customer's account presents a security or fraud risk;

  • the Customer's messaging activity threatens the reputation or deliverability of Abelo or a messaging provider;

  • the Customer fails to pay amounts due;

  • the Customer uses the Services unlawfully;

  • a third-party messaging provider requires suspension;

  • Abelo is required to do so by law or a competent authority; or

  • continued access creates a material risk to Abelo, its infrastructure, its messaging partners, or other customers.


Where reasonably practicable, Abelo will notify the Customer of the reason for suspension and provide an opportunity to remedy the issue.


Immediate suspension may occur where reasonably necessary to prevent fraud, abuse, security threats, unlawful activity, or material harm to Abelo, its customers, recipients, or third parties.


14.5 Termination by Abelo


Abelo may terminate the Customer's access to the Services if the Customer materially breaches these Terms, the Acceptable Use Policy, or another applicable agreement and fails to remedy the breach within a reasonable period after receiving notice, unless immediate termination is permitted or reasonably necessary under these Terms.


14.6 Termination by a Messaging Provider


Viber or another third-party messaging provider may independently suspend or terminate access to its messaging services.


Abelo is not responsible for termination or suspension imposed directly by a third-party messaging provider where such action results from the provider's policies, regulatory requirements, network controls, or other circumstances outside Abelo's reasonable control.


15. Acceptable Use Policy


Your use of Abelo is also subject to the Abelo Acceptable Use Policy.


The AUP contains additional requirements concerning:


  • marketing consent;

  • prohibited lists and data sources;

  • spam;

  • prohibited industries and content;

  • messaging compliance;

  • security;

  • technical abuse;

  • regulatory requirements; and

  • enforcement and suspension.


A violation of the AUP constitutes a violation of these Terms.


The current AUP is available at:

https://abelo.ai/legal/acceptable-use-policy


16. Privacy and Data Protection


Your use of Abelo is also subject to the Abelo Privacy Policy.


The Privacy Policy explains how we collect, use, store, disclose and protect personal data and distinguishes between data for which Abelo acts as a controller and data processed on behalf of customers.


The current Privacy Policy is available at:

https://abelo.ai/legal/privacy-policy


Where Abelo processes personal data on behalf of the Customer as a data processor, such processing is governed by the Abelo Data Processing Agreement ("DPA"), which is incorporated into and forms an integral part of these Terms.


The current DPA is available at:

https://abelo.ai/legal/dpa


17. Disclaimers


To the maximum extent permitted by applicable law, the Services are provided "as is" and "as available".

  • your violation of applicable privacy, marketing or telecommunications laws;

  • your Customer Data; or

  • your infringement of third-party rights.


We will provide reasonable notice of any claim for which indemnification is sought and reasonable cooperation in defending the claim.


20. Force Majeure

Neither party will be liable for failure or delay in performing its obligations where such failure or delay results from circumstances beyond its reasonable control.


Such events may include, without limitation:


  • natural disasters;

  • fire or flood;

  • war or terrorism;

  • civil unrest;

  • governmental actions;

  • telecommunications or internet failures;

  • power outages;

The affected party will use reasonable efforts to mitigate the effects of the event and resume performance as soon as reasonably practicable.


21. Third-Party Services


Abelo may integrate with or depend upon third-party services, platforms and providers.


These may include e-commerce platforms, messaging networks, telecommunications operators, payment providers, cloud infrastructure providers, analytics services and other technology providers.


Your use of third-party services may be subject to separate terms and policies.


Abelo is not responsible for the availability, functionality, security or policies of third-party services that are outside our reasonable control.


22. Changes to These Terms


We may update these Terms from time to time to reflect changes to our Services, technology, business practices or legal requirements.


When we make material changes, we will update the "Last Updated" date and, where appropriate, notify you through the Platform, email or another reasonable communication channel.


Unless otherwise specified, the revised Terms become effective when published.

Service-related communications are not marketing communications and may be sent even if you have opted out of promotional communications.

You are responsible for keeping your account email address and contact information current.


24. Assignment


You may not assign or transfer your rights or obligations under these Terms without our prior written consent, except where the transfer occurs as part of a merger, acquisition or sale of substantially all of your assets.


We may assign or transfer these Terms to an affiliate or in connection with a merger, acquisition, corporate reorganization or sale of all or substantially all of our assets.


25. Severability


If any provision of these Terms is found to be invalid, illegal or unenforceable, that provision will be interpreted or modified to the minimum extent necessary to make it enforceable, where permitted by law.


The remaining provisions will remain in full force and effect.


26. No Waiver


Failure by either party to enforce any provision of these Terms does not constitute a waiver of that provision or of the right to enforce it later.


27. Entire Agreement


These Terms, together with any applicable commercial agreement, DPA, AUP and Privacy Policy, constitute the agreement between you and Abelo regarding your use of the Services and supersede prior understandings concerning the same subject matter, except where a written agreement expressly provides otherwise.

These Terms and the relationship between you and Trebbble S.A. are governed by and interpreted in accordance with the laws of Greece and applicable European Union law.


Before initiating legal proceedings, the parties will make reasonable efforts to resolve any dispute amicably.
