Esendex Australia: 2 Cents per SMS Promotion Terms and Conditions

These promotion terms and conditions (the “Promotion Terms“) govern the “2 Cents per SMS” promotional offer (the “Promotion“) made available by Esendex Australia Pty Limited ACN 113 596 580 of Level 21, 55 Collins Street, Melbourne VIC 3000, Australia (“Esendex“, “we“, “us” or “our“).

By participating in the Promotion, you (the “Customer“, “you” or “your“) accept these Promotion Terms. The Promotion Terms are supplemental to, and must be read together with, the Esendex Terms of Service available at https://enhancedsupport.esendex.co.uk/terms-of-service/ (the “Terms of Service“) and all documents incorporated into them, including the Acceptable Use Policy and Data Processing Agreement. Capitalised terms used but not defined in these Promotion Terms have the meaning given to them in the Terms of Service.

In the event of any inconsistency between these Promotion Terms and the Terms of Service, these Promotion Terms prevail to the extent of the inconsistency, but only in respect of the Promotion.

1.              THE PROMOTION

1.1. The Promotion entitles an Eligible Customer to a promotional rate of AUD 0.02 per SMS message part (with each part of a multi-part SMS charged separately) for SMS sent to Australian numbers through the Connect API during the Promotional Period (the “Promotional Rate“).

1.2. The Promotional Rate applies only to SMS sent by the Customer to Australian numbers. SMS sent to any other numbers are charged at the applicable Tariff displayed in the Platform.

1.3. The Promotional Rate is exclusive of GST and any other taxes, duties, levies or similar governmental charges, which are payable by the Customer at the applicable rate.

2.              ELIGIBILITY

2.1. To qualify for the Promotion, a Customer must satisfy all of the following conditions (an “Eligible Customer“):

(a) the Customer must be a new customer that has not held an Esendex account at any time in the 365 days immediately preceding the date on which it opens its account for the purpose of the Promotion;

(b) the Customer must be a Connect API customer and must send the relevant SMS through the Connect API;

(c) the SMS must be sent to Australian numbers; and

(d) the Customer must send its first live (paid) SMS on or before 17:00 (AEDT) on 15 December 2026 (the “Qualifying Date“).

2.2. The Promotion is available to business customers only and is not available to consumers acquiring the Services wholly or predominantly for personal, domestic or household use or consumption.

2.3. Each Customer may participate in the Promotion once. The Promotion may not be used in conjunction with any other offer, discount or negotiated rate unless we agree otherwise in writing.

3.              PROMOTIONAL PERIOD AND REVERSION

3.1. The “Promotional Period” is the period of 90 consecutive days commencing on the date on which the Eligible Customer sends its first live (paid) SMS, on or before the Qualifying Date.

3.2. The Promotional Rate applies only during the Promotional Period. At the end of the Promotional Period, the Customer’s account will automatically revert to the rate set out in the Customer’s signed contract or order form with Esendex to apply after the Promotional Period, subject to the terms of that contract or order form (including any pricing that depends on the Customer’s SMS volumes) (the “Standard Rate“).

3.3. The Promotional Rate applies only to SMS sent during the Promotional Period, irrespective of delivery, non-delivery or receipt by the intended recipient, in accordance with the Terms of Service.

4.              OFFER AVAILABILITY

4.1. The Promotion is open from 26 October 2026 until the Qualifying Date. A Customer that does not send its first live (paid) SMS by the Qualifying Date is not eligible for the Promotion.

4.2. (a) General and regulatory changes: We may vary, suspend, extend or withdraw the Promotion, or amend these Promotion Terms, at any time, including where necessary to comply with any applicable law or regulatory requirement. Any such change will be published on the campaign landing page and will not affect the Promotional Rate already applying to an Eligible Customer for the remainder of its current Promotional Period, unless the variation, suspension or withdrawal is required to ensure compliance with applicable law or regulatory requirements.

(b) Customer breach and misuse: We may immediately withdraw the Promotional Rate and apply the Standard Rate (or suspend or terminate access to the Services in accordance with the Terms of Service) if we reasonably determine that the Customer has breached the Terms of Service or the Acceptable Use Policy, or has engaged in activity that is fraudulent, constitutes Artificial Inflation of Traffic (AIT) or otherwise misuses the Services.

5.              GENERAL

5.1. Participation in the Promotion is subject to the Customer satisfying our KYC Process and account verification requirements, and to the Customer’s compliance with the Terms of Service and the Acceptable Use Policy.

5.2. Nothing in these Promotion Terms excludes, restricts or modifies any consumer guarantee, right or remedy conferred on the Customer by the Australian Consumer Law (Schedule 2 of the Competition and Consumer Act 2010 (Cth)) or any other applicable law that cannot be excluded, restricted or modified by agreement.

5.3. These Promotion Terms are governed by and are to be construed in accordance with the laws of Victoria, Australia. Each party irrevocably submits to the exclusive jurisdiction of the courts of Victoria and courts of appeal from them for determining any dispute arising out of or in connection with the Promotion.
