Lifecycle automation. The right message, at the right moment.
Behaviour-triggered lifecycle sequences across email, SMS, and in-app — personalized, adaptive, and continuously improving. Agents craft the messaging, select the timing, and iterate based on engagement signals. Hellyeah’s AI-native growth infrastructure connects lifecycle triggers, content generation, and send-time optimization into one autonomous system.
What is AI lifecycle automation?
Lifecycle automation is the practice of sending targeted messages to users based on their actual behaviour — which features they use, where they drop off, how engaged they are — rather than a fixed drip schedule that treats every user the same way.
Traditional drip tools execute predefined sequences: sign up on Monday, get email 1 Tuesday, email 2 Friday, email 3 the following Tuesday. AI lifecycle agents pursue outcomes: activate this user, retain this customer, convert this trial. They select the message, timing, and channel that the data says will work best for this specific person right now.
Hellyeah’s Forge platform provides the execution layer: behaviour-triggered flows across email, SMS, and in-app that personalize at the individual level and iterate based on engagement signals — without a sequence manager or template queue.
- ✕Fixed time-based sequences for all users
- ✕Segment-level personalization at best

- ✕Single channel — typically email only
- ✕No real-time response to behaviour changes
- ✓Behaviour-triggered flows responding to real user actions
- ✓Individual-level personalization — content, timing, channel
- ✓Agents rewrite and iterate sequences automatically
- ✓Email, SMS, and in-app — channel selected per message
- ✓Real-time trigger logic reacts to behaviour as it happens
From behaviour event to personalized message in four steps.
Connect your product analytics and CRM, define your lifecycle goals, and agents handle everything — trigger logic, personalized message generation, channel selection, and continuous optimization.
Event Trigger
Connect your product analytics and CRM. Define the behaviour events that trigger lifecycle flows — feature activation, trial day 7 without conversion, 14 days of inactivity, or any custom signal your data layer captures.
Audience Segmentation
Agents segment users dynamically based on plan, usage depth, intent signals, and CRM attributes — ensuring every user receives messaging calibrated to their specific context, not a broad segment bucket.
Message Generation
Agents generate personalized message content for each user — subject lines, body copy, CTA — following your brand voice guidelines and adapting tone and focus to the individual's journey stage. You approve before any new sequence goes live.
Optimize and Iterate
Agents measure engagement and downstream conversion for every message sent, rewrite underperforming variants, and adjust send timing to match individual engagement windows — compounding performance improvement without manual A/B test management.

Five lifecycle moments. One agent layer.
Hellyeah's lifecycle agents cover every critical moment in the customer journey — from onboarding to conversion to long-term retention — across all channels.
Onboarding Sequences
Agents design and execute behaviour-triggered onboarding journeys — detecting activation milestones, identifying users at risk of dropping off, and sending personalized nudges across email, SMS, and in-app at exactly the right moment in the user's journey.
Win-back Campaigns
Agents identify churned or at-risk users from CRM and product signals, generate personalized re-engagement messages tailored to each user's previous usage pattern, and send them via the channel most likely to get a response — without a manual segment build.
Product Adoption Nurture
Agents monitor feature adoption signals and send targeted guidance to users who haven't discovered high-value features. Message content is generated based on the user's current usage depth and the specific feature they're missing — not a one-size nurture sequence.
Trial-to-Paid Conversion
Agents track trial engagement signals — sessions, features activated, team invites sent, integrations connected — and send conversion-optimized messages at the moments of highest intent. Agents select whether to include a discount offer based on individual intent score, not blanket policy.
Re-engagement Flows
Agents detect user inactivity before it becomes churn, trigger re-engagement sequences calibrated to the user's previous engagement patterns, and measure downstream reactivation — continuously improving the timing and content of re-engagement without manual updates.
Three layers. One growth engine.
Hellyeah's lifecycle automation stack combines three platforms that work together — giving you an AI-native messaging engine that personalizes, triggers, and iterates across every channel from a single command layer.
The AI marketing agent that accepts lifecycle goals via CLI, SDK, or WhatsApp and orchestrates the full trigger, personalization, and send pipeline across email, SMS, and in-app.
Autonomous growth systems that handle trigger logic, audience segmentation, message generation, channel selection, and engagement signal processing — running continuously without human intervention.
Real-time user intelligence and attribution. Agents use Mutation's signals to segment accurately, detect intent changes, and measure the downstream impact of every lifecycle message on revenue.
Built for teams that care about retention.
AI lifecycle automation works for teams running email-heavy campaigns and product-led growth teams relying on in-app signals — the agents adapt to your data layer and channels.
Lifecycle marketers
Stop managing sequences manually. Agents handle trigger logic, message generation, and performance iteration — you focus on strategy and the moments that matter most in your customer journey.
CRM managers
Get individual-level personalization without a data engineering project. Agents connect to your CRM, ingest behaviour signals, and create personalized flows that adapt as users change.
Product-led growth teams
Activate more trial users and improve trial-to-paid conversion without adding headcount. Agents detect intent signals and intervene with the right message before users churn.
Consumer apps and e-commerce brands use Hellyeah’s consumer tech marketing automation to run lifecycle and paid channels from one agent layer.
Lifecycle automation, answered.
Everything you need to know before deploying autonomous lifecycle automation agents at your company.
What is lifecycle marketing automation?
Lifecycle marketing automation is the practice of sending the right message to the right person at the right moment in their customer journey — triggered by their actual behaviour, not a fixed time delay. Traditional drip sequences send everyone the same messages on a fixed schedule. Lifecycle automation responds to what a user actually does: which features they activate, where they drop off, what they buy, and when they go quiet. AI agents take this further by personalizing message content, timing, and channel selection dynamically for each user rather than applying segment-level rules.
How does AI lifecycle automation differ from traditional email automation?
Traditional email automation follows predefined rules and time-based sequences — if a user signs up, send email 1 on day 0, email 2 on day 3, email 3 on day 7. Everyone gets the same content on the same schedule. AI lifecycle agents observe individual behaviour signals — feature usage, session depth, plan type, support history — and generate personalized messages for each user, selecting the optimal timing and channel. Agents also iterate message content based on open rates, click-through rates, and downstream conversion — without requiring a human to rewrite sequences.
Which channels does lifecycle automation support?
Hellyeah's lifecycle agents operate across email, SMS, and in-app push notifications. Channel selection is automated — agents choose the channel most likely to reach the user effectively based on their engagement history and the message type. A high-urgency win-back message might go via SMS; an onboarding tip goes via in-app; a renewal reminder goes via email. You can configure channel preferences and exclusions per user segment or at the account level.
Which CRM and marketing tools does Hellyeah integrate with?
Hellyeah's lifecycle agents integrate with Salesforce, HubSpot, Intercom, Braze, Customer.io, Klaviyo, Segment, and other major CRM and CDP platforms via API. Behaviour signals flow from your product analytics (Amplitude, Mixpanel, PostHog) and your CRM into the agent layer, which uses them for trigger logic and personalization. You don't need to replace your existing tools — agents orchestrate across them.
How deep does personalization go?
Agents personalize at the individual level — not just segment-level substitution like first name or company. Personalization includes message tone (formal vs casual based on user context), content focus (which feature to highlight based on usage history), offer inclusion (whether to include a discount based on intent signals), and send time (based on the user's historical engagement window). As agents accumulate engagement data, personalization fidelity improves continuously.
How does Hellyeah handle compliance — unsubscribes, GDPR, and CAN-SPAM?
Hellyeah agents respect unsubscribe preferences, suppression lists, and opt-out signals in real time across all channels. GDPR compliance is enforced at the data layer — agents only access and process user data for the purposes you've configured, with full audit logging of every data access and message send event. CAN-SPAM and CASL compliance (unsubscribe links, sender identification, postal addresses) is automatically included in all outbound email. Suppression list sync with your CRM and ESP runs continuously.
How long does it take to set up the first lifecycle flow?
Most teams have their first behaviour-triggered flow live within 24–48 hours of connecting their product analytics and CRM. You define the trigger event (e.g., user completes onboarding step 2 without reaching step 3), the goal (e.g., activate the user within 7 days), and your brand voice guidelines. Agents generate the message sequence, you approve, and it goes live. No template queue, no engineering sprint, no campaign builder drag-and-drop.
How do agents learn and improve over time?
Agents observe engagement signals — open rates, click-through rates, reply rates, downstream conversion events — for every message they send. Underperforming message variants are rewritten and tested against the current winner. Timing adjustments are made based on when individual users actually engage. Agents also learn from cohort patterns — if a particular user persona consistently converts better with shorter messages sent earlier in the trial, that learning is applied across similar users automatically.
