Comprehensive Push Notification Telemetry Audit

Service Overview & Target Audience

The Comprehensive Push Notification Telemetry Audit is tailored for mobile product engineering leads, telemetry architects, and growth infrastructure teams managing native iOS (Swift/Objective-C) and Android (Kotlin/Java) apps with over 500,000 monthly push dispatches.

If your marketing or backend teams observe persistent discrepancies between gateway “send” confirmations, client-side banner displays, and user open actions, this audit establishes verifiable telemetry across every layer of the notification lifecycle.

What the Flagship Audit Delivers

By the conclusion of the 10-day audit, your engineering organization receives:

1. Client-Side Notification Extension Code Audit: Complete review of iOS UNNotificationServiceExtension and Android FirebaseMessagingService implementations, isolating memory limits, execution time-outs, and unhandled silent failures.
2. End-to-End Acknowledgment Telemetry Spec: A hardened, lightweight protocol specification allowing devices to report background reception before user interaction occurs.
3. Attribution Discrepancy Matrix: A clear diagnostic breakdown distinguishing direct notification opens, interactive notification action button taps, and influenced 24-hour conversion sessions.
4. Gateway Configuration & Priority Review: Inspection of APNs headers (apns-push-type, apns-priority, apns-expiration) and FCM options (priority: high, direct_boot_ok, data-only vs. notification payloads).
5. Actionable Pull Request (PR) Prototypes: Ready-to-merge code branches demonstrating optimized extension lifecycle management and background telemetry flush routines.

Included vs. Excluded Scope

Included in Scope

• Source code analysis of mobile push handling modules and extensions.
• Inspection of payload JSON schemas and custom deep link routing logic.
• Live device packet inspection across physical test devices (iOS 16-18, Android 12-15).
• Audit of backend webhook ingestion endpoints for receipt telemetry.
• Direct delivery latency testing under battery-saving and Doze modes.
• Delivery of comprehensive 35+ page diagnostic report and architectural recommendations.
• Two 90-minute technical review sessions with your lead engineers.

Excluded from Scope

• Rewriting full backend messaging brokers or database storage layers.
• Purchasing or reselling proprietary marketing automation software licenses.
• Managing active advertising or promotional messaging campaigns.
• Direct customer support management for end-user notification complaints.
