I went straight for engagement metrics and kind of forgot to anchor on what 'success' even means for a channel like SMS.

Suggested Approach

Start by clarifying the goal of the SMS feature—likely to increase user engagement and business outcomes—then define success metrics across the funnel: adoption, usage, and impact. Structure your answer around a metrics framework that ties directly to Intercom's business model and customer value.

Pro tip: Differentiate between leading indicators (e.g., SMS send rate) and lagging indicators (e.g., retention lift), and emphasize that the ultimate measure is whether SMS drives incremental business value for Intercom's customers, not just usage.

1. Clarify the feature's goal and target users

Confirm that the SMS feature aims to help businesses engage users via text, and identify primary users (businesses) and end users (their customers).

2. Define success metrics across the funnel

Map metrics to adoption (e.g., % of eligible businesses enabling SMS), engagement (e.g., messages sent, open/response rates), and outcomes (e.g., conversion, retention, CSAT).

3. Prioritize metrics by business impact

Select a North Star metric (e.g., incremental revenue per business using SMS) and supporting metrics that reflect both customer and Intercom value.

4. Establish measurement methodology

Use A/B testing or holdout groups to isolate SMS impact, and track cohort-based retention and expansion revenue for adopters vs. non-adopters.

5. Iterate and set targets

Define benchmarks and targets, monitor leading indicators, and plan to refine metrics as the feature matures and more data becomes available.

Key Points to Mention

  • Adoption rate: percentage of businesses that enable and actively use SMS
  • Engagement metrics: messages sent per business, delivery rate, response rate, and click-through rate
  • Business outcomes: conversion lift, retention improvement, and customer satisfaction (CSAT/NPS) for businesses using SMS
  • Intercom's business impact: expansion revenue, churn reduction, and upsell opportunities from SMS adopters
  • Incremental value: compare SMS users to a control group to ensure metrics are not just correlation
  • Guardrail metrics: opt-out rate, spam complaints, and cost per message to ensure sustainable growth
