AI Voice Agent for User Reactivation — DeepAgent
Do you have registered users who never activated? With VEGA, reopen conversations, understand blockers, and turn zeros into opportunities. Want to see how?
You have hundreds of people registered for your product who have never actually used it. They aren't cold leads: they've already raised their hand. They simply stopped at the first step. In four days, we entrusted VEGA, our AI voice agent for user reactivation, with 1,416 call attempts targeting this exact segment: 285 real conversations, 33 reopened paths to a support demo, and — crucially — a precise map of the reasons why activation gets stuck. ## TL;DR - 1,416 attempts in 4 days on registered but inactive users; 285 conversations, 33 positive outcomes. - Conversations with positive outcomes 3.4× longer than average: voice uncovers the “whys.” - Bottleneck: reachability. No-answers and voicemails for 79.7% of attempts. - Improvements: time slots, recency, number quality, recall strategy (max 7 attempts). - Extra output: 8 onboarding friction points to guide roadmap, messaging, and segmentation. ## The Client and PLG Context Once again, the case study is us: DeepAgent, a platform for creating and deploying AI voice and chat agents. Like any self-serve product, the critical point is the gap between registration and the first agent created. Those who pass that step stay; those who don't rarely return. To avoid editorial overlap: this case is about product-led growth for already registered users who have not completed activation. For inbound lead qualification, see [the dedicated case study](/agente-vocale-ai-qualifica-lead-caso-studio/). For outbound pre-qualification on cold lists, see the [Fincontinuo case study](/agente-vocale-ai-prequalifica-outbound-fincontinuo-caso-studio/). ## The Challenge: Failed Activation is a Silent Problem Someone who registers and doesn't activate showed interest at a specific moment, perhaps weeks ago. A follow-up email to this segment performs poorly precisely because it's a channel already ignored. Analytics tells you where they stopped, not why: technical difficulties, product misunderstanding, or changed priorities all look exactly the same on a dashboard. And the volume makes manual calls impractical: calling thousands of registrants for two minutes each is unsustainable. This is why recovering registered but inactive users often remains a good intention left unexecuted. ## VEGA's Operational Flow An AI voice agent for user reactivation starts with a concrete signal in the product. The flow used from March 24th to 27th: 1) Cluster identification: Registered users who haven't yet created their first agent. 2) First outbound contact: VEGA verifies identity, introduces itself, and asks for a few minutes. 3) Initial motivation: What prompted registration and what use case was being considered. 4) Blockage identification: Technical difficulties, incomplete understanding, time constraints, changed priorities, or lost interest. 5) Support proposal: A 15-minute walkthrough with the team to unblock configuration. 6) Availability and contact details: Day, time slot, and (if needed) email confirmation/correction. 7) Handoff and recall: Positive outcome = progression towards re-contact or demo; up to 7 recall attempts for those not reached.  ## Results: 1,416 Attempts, 285 Conversations, 33 Reopened Paths | Metric | Value | |---|---| | Call attempts (March 24–27) | 1,416 | | Completed conversations | 285 · 20.1% of attempts | | Positive outcomes (recontact / demo started) | 33 | | Success rate on actual conversations | 11.6% — 1 outcome per 8.6 conversations | | Success rate on total attempts | 2.3% — 1 outcome per 42.9 attempts | | Conversation minutes | 377.7 · 6.3 hours | | Average completed conversation duration | ~44 seconds | | Average positive outcome conversation duration | ~149 seconds (2'29") | The most interesting signal isn't a percentage, it's a ratio: conversations that end well last over three times the average. Forty-four seconds is the time it takes for a “no, thanks.” Two and a half minutes is the time it takes for someone to explain where they got stuck. The call isn't a reminder: it's a diagnosis.  ## Daily Trend: Conversion Holds, Volume Doesn't | Day | Attempts | Conversations | Positive Outcomes | Success | |---|---|---|---|---| | March 24 | 74 | 28 | 4 | 14.3% | | March 25 | 365 | 101 | 11 | 10.9% | | March 26 | 568 | 125 | 14 | 11.2% | | March 27 | 409 | 31 | 4 | 12.9% | March 26 concentrates maximum volumes and outcomes, but the key data point is stability: between 10.9% and 14.3% success on conversations every day. The quality of conversation does not degrade with scale — a clear difference compared to a human team under load. ## The Bottleneck: Reachability Out of 1,416 attempts, 749 were no-answers and 379 ended in voicemail: together, these account for 79.7% of attempts. The limit isn't persuasion; it's getting the phone to ring at the right time. Where to act in a SaaS product reactivation campaign: - Time slots and days with high response rates. - Recency of the segment (call sooner, not weeks later). - Quality of numbers and demographic verification. - Recall strategy (cadence, maximum number, windows). With the same conversion rate on conversations, increasing contactability from 20% to 30% proportionately boosts outcomes.  ## Insights That Change the Product The 285 conversations produced what analytics cannot: users' own words. Eight recurring themes, useful for mapping onboarding friction and failed activation: - Technical onboarding difficulties (errors/obstacles in the first agent creation). - Need for operational guidance (assisted step-by-step setup). - Time and priorities (request for a callback later). - Product understanding (models, voice and chat use cases). - Perceived value and trust (maturity of AI voice agents). - Demos and appointments (slots, confirmations, email updates). - Disinterest and outdated registrations (don't remember or chose something else). - Unmanageable contacts (voicemails, no answers, interrupted calls). Operational translation: the first two points guide the roadmap; the fifth, messaging; the seventh, segmentation. Not assumptions, but hundreds of recorded conversations. ## Impacts on Funnel, Costs, and Method - Funnel: 33 reopened paths from a segment that, without voice, was worth zero by definition. - Costs: 1,416 attempts in 4 days and 6.3 hours of talk time; impossible for a human team to sustain for free, unactivated users. - Product: the eight emerging blockers improve the activation of all future registrants. Methodological note: by “positive outcome” we mean goal_met=true (advancement towards re-contact or demo). This does not imply a verified meeting on the calendar for this period: no uniquely attributable bookings were found, nor were they inferred. ## Conclusion From March 24th to 27th, VEGA transformed a dormant segment into 33 opportunities and a wealth of actionable insights. For these users, voice is doubly valuable: it reactivates and it explains. Want to test the same flow on your product? Request a demo and try VEGA in real-time.

We select the cluster with the highest intent: registered users who have not completed the first key event (e.g., agent creation). We cross-reference recency, origin, and product data to prioritize those most likely to become active again. This makes it more effective to recover registered but inactive users without wasting calls. ### What is the typical ROI of an AI voice reactivation campaign? It depends on contactability and the value of the unlocked step. In this SaaS product reactivation campaign: 20.1% conversations from attempts, 11.6% successes from conversations, and 2.3% from attempts. The true ROI also includes the insights that reduce friction and increase future activation. ### How does VEGA integrate with my stack and product data? VEGA connects to CRM and data layers (onboarding events) to identify who to call, personalize the conversation, and log outcomes. Insights are tagged by theme, allowing you to measure onboarding friction and failed activation over time and align your roadmap, messaging, and segmentation. ### Why use voice instead of email or asynchronous chat? Voice reduces ambiguity and friction: you gain context in minutes, not days. Here, conversations with positive outcomes lasted 3.4× the average, a sign of genuine engagement. An AI voice agent scales without quality degradation, while emails and chat suffer from low response rates in already silent segments. ### How long does it take to launch and what internal resources are needed? Typically 1–2 weeks: segment definition, script, and objectives; CRM/calendar integration; testing and go-live with recalls. A product/CRM owner and a sales or success representative are needed for manual handoffs. VEGA manages automation, reporting, and team handoffs.
