Spend less.Deliver with proof.

MarketHK is a messaging and authentication operations platform developed by iGears Technology Limited, supporting Email, WhatsApp, SMS and TOTP. Its philosophy is "save where you can, deliver where you must": select configured channels by purpose, consent, recipient capability and cost, then record each attempt. Actual delivery depends on carriers, mailbox providers, Meta, devices and networks, so the platform does not guarantee a particular delivery rate or time.

You can manage channels, consent, approvals, cost and delivery states in one workspace. The platform can select a suitable lower-cost channel and handle fallback under configured rules, but it cannot guarantee third-party delivery. Uses include:

• Routing and fallback: Routes among Email, WhatsApp and SMS under configured policy, then handles fallback after an applicable failure result.
• Identity Verification Upgrade: Replaces traditional SMS OTP with low-cost, highly secure TOTP.
• Centralized Management and Reconciliation: Manage all channels through one backend and use the Unified Ledger to centrally view sending volumes and performance reports.
• Compliance and security controls: Manage opt-in / opt-out records, suppression and pre-send approvals. These tools support compliance work but do not replace the customer's legal responsibility.

Before sending, the routing engine selects a channel from recipient touchpoints, consent status, message type and an administrator-configured policy. Fallback starts only after a result that the policy treats as failed or timed out. Each real attempt may incur provider charges, and delayed provider receipts can still create overlapping attempts. MarketHK records the path, state and known cost in the ledger so teams can reconcile and improve it.

MarketHK provides tools and project assistance for continuing Hong Kong messaging and privacy requirements:

• OFCA SMS Sender Registration Scheme: The scheme launched in December 2023. MarketHK can help inventory Sender IDs and prepare application, test and cutover materials; eligibility, timing and final approval remain with OFCA or the relevant provider.
• PDPO direct-marketing requirements: The platform can centralize opt-in / opt-out, suppression and sending records for customer compliance workflows and review. Legal compliance still depends on list source, purpose, consent and actual operations.

TOTP (Time-based One-Time Password) is an authentication technology based on RFC 6238. Codes are generated locally on the device, generally update every 30 seconds and do not need to travel over a telecom network. MarketHK supports this implementation flow:

• TOTP API integration: A customer system uses a scoped workspace API key for enrol, confirm, challenge and verify endpoints. Integration effort depends on the customer's system.
• Third-party Authenticator: Users scan an enrolment QR code and generate codes in compatible apps such as Google, Microsoft, 1Password or Bitwarden Authenticator.

There are two main reasons:

• Cost Reduction: TOTP verification codes are generated locally by the device and do not go through the telecom network, making the telecom cost for this portion close to zero.
• Security: SMS can be intercepted at the telecom layer, while TOTP adheres to the RFC 6238 international standard, offering higher security.

The positioning and division of labor among the three are different:

• International CPaaS (e.g., Twilio): Primarily sells communication channels; customers must develop their own routing logic.
• WhatsApp Specialized Platform (e.g., SleekFlow): Focuses on conversation flow.
• MarketHK: Features a built-in cross-channel routing engine (Email, SMS, and WhatsApp Business), built-in TOTP authentication API, and provides support and managed services from a local Hong Kong team.

MarketHK retains a Direct Send flow so a user can specify recipients and a channel. Actual sending remains subject to workspace roles, plan quotas, consent and suppression, template approval, provider readiness and any applicable approval requirement.

Savings depend on message purpose, available recipient touchpoints, channel prices, failure and retry rates, and high-risk cases that must retain SMS. MarketHK can build a baseline and migration estimate from your actual data; a quotation or estimate does not guarantee a particular saving.

You can send the following two major types of WhatsApp messages through MarketHK:

• Utility, Marketing, and Authentication categories: These messages require adding a WhatsApp message template in the MarketHK backend in advance and submitting it automatically for Meta review. Once approved, you can select the template for bulk sending or notifications in the "Direct Send" or "Campaign" functions.
• Service category: The MarketHK backend has a built-in WhatsApp Business inbox. When a customer actively sends the first message, businesses can reply directly within the 24-hour conversation window without prior template submission to Meta for review. After 24 hours, the conversation window automatically closes, and a pre-approved template must be used to proactively contact the customer again.
