Turn survey responses into Amplitude events and user properties for sharper behavioral analysis
Amplitude is the product analytics tool where many teams already live — funnels, retention, cohort analysis, experimentation. Survey data added to that mix makes every analysis richer: instead of looking at what users did, you can now ask the tool what users said and did. Connecting Responsly to Amplitude sends survey submissions as first-class events and user properties, ready for any analysis the team runs.
Where Amplitude + Responsly shines
Onboarding funnels split by self-reported intent
A post-onboarding survey captures primary use case. Funnels for ‘completed setup → reached activation’ can now split by use case, revealing where each segment drops off and where to improve. Generic onboarding becomes intent-specific.
NPS bands across every report
Writing nps_band (promoter / passive / detractor) as a user property means every retention curve, feature-adoption chart, and funnel can split by NPS. Differences surface immediately: promoters retain at 85%, detractors at 42%. That single chart justifies CX investment for a year.
Feature-request cohorts tied to actual usage
A feature-request survey writes the requested feature to a user property. Amplitude can then ask: are requesters power users or newcomers struggling to find existing features? The answer shapes prioritization.
Retention split by self-reported churn risk
A churn-risk survey near renewal marks users with renewal_intent. Retention charts over the next 60 days quickly validate whether the self-reported risk matched reality — and the prediction accuracy improves the survey’s usefulness.
Experiment targeting from survey answers
Amplitude Experiment uses the survey-derived user properties for experiment targeting. Ship the new feature only to users who said they want it; measure lift on that cohort specifically.
Connecting Responsly to Amplitude
- Copy your project API key from Amplitude’s settings.
- Paste it into Responsly’s Amplitude integration.
- Configure event name and properties per survey. Default:
Survey Completedwith answer properties. - Decide on user-property writes. Structured scores and segmentation-relevant fields.
- Set identify strategy —
user_id, email, ordevice_idconsistent with your existing Amplitude setup. - Test with a sample response and verify in Amplitude’s Live View.
Practices that keep Amplitude clean
Structured answers as user properties; free-text on events. User properties drive cohorts — keep them low-cardinality and meaningful.
Consistent event names. Survey Completed with survey_name as a property beats a dozen different event names.
Watch cardinality and cost. High-volume micro-surveys add event volume. Aggregate or filter if pricing becomes a concern.
Mirror to a warehouse. Amplitude is great for exploration; warehouse storage via reverse-ETL keeps long-term analyses possible. The Segment integration handles both simultaneously.
Close the loop with product. Survey insights should drive product decisions tracked in Amplitude. Document the connection between survey finding and feature shipped — it keeps the program funded. See our voice of customer guide for a framework to structure that loop across teams.
Behavior data plus customer voice in the same tool
Connect Responsly to Amplitude and every survey response joins the behavioral data your team already analyzes. Funnels, retention, cohorts, and experiments all get smarter — not because a new tool entered the stack, but because the existing one finally sees what users actually said.
