# Lifecycle email campaigns

> Draft nurture, re-engagement, and onboarding sequences in your brand voice at the moments that matter.

Lifecycle email is the workhorse of B2B marketing — and the place that scales worst with headcount. A lifecycle Agent drafts the sequences that match each segment, lifecycle stage, and trigger so you can run more campaigns without copying templates into Google Docs.

## When this pays off

<CardGroup cols={2}>
  <Card title="Lifecycle is templated" icon="files">
    You're copy-pasting "Welcome Series v3" docs between every product launch instead of running per-launch sequences.
  </Card>

  <Card title="Trigger moments are missed" icon="bell-slash">
    Trial ending, contract renewing, feature unused — these moments deserve sequences and currently get nothing.
  </Card>

  <Card title="Brand voice drift" icon="comments">
    Different team members write each campaign and the voice has slipped across them.
  </Card>

  <Card title="Re-engagement is overdue" icon="hourglass">
    A dormant-list re-engagement campaign keeps getting deprioritized because the copy work is the bottleneck.
  </Card>
</CardGroup>

## The shape of this use case

A lifecycle Agent takes a segment + trigger and returns a multi-step email sequence in your voice.

<CardGroup cols={2}>
  <Card title="Inputs" icon="arrow-right-to-bracket">
    Segment definition, lifecycle stage, triggering event, campaign goal.
  </Card>

  <Card title="Sources" icon="globe">
    Brand voice docs, past-campaign copy, persona definitions, product positioning, your marketing automation platform.
  </Card>

  <Card title="Output" icon="file-lines">
    A drafted sequence — subject lines, body copy, send timing, CTA per step — ready for review.
  </Card>

  <Card title="Delivery" icon="paper-plane">
    Drafted into [HubSpot](/integrations/popular-integrations/hubspot) or [Marketo](/integrations/popular-integrations/marketo) for review, written to a doc for marketing approval, queued in your ESP.
  </Card>

## Where to start

Two ways in, depending on whether you want something running today or built to your exact spec.

<CardGroup cols={2}>
  <Card title="Clone a pre-built Agent" icon="copy">
    Open the **[Email Marketing Strategist](https://marketplace.relevanceai.com/listing/28783038-03f0-4aec-9c76-4b28452b6e33)**. More in the [Marketplace](/get-started/marketplace/introduction).
  </Card>

  <Card title="Build your own" icon="hammer">
    Start from scratch in the [builder](/build/introduction), or by describing it in Claude Code or Cursor with [Programmatic GTM](/get-started/core-concepts/programmatic-gtm).
  </Card>
</CardGroup>

Either way, these are prompts your team can use on day one:

* *"Draft a 4-step welcome series for new free-trial users in HubSpot — friendly tone, focus on activating the dashboard feature."*
* *"Write a re-engagement sequence for trial users who haven't logged in for 30 days."*
* *"Give me a 3-touch renewal sequence for accounts in the 90-day renewal window."*

## Where to take it

Once it's running, deepen it in three moves:

<CardGroup cols={3}>
  <Card title="Give it a playbook" icon="book">
    Shape it with a [prompt](/build/agents/build-your-agent/prompt), your brand voice in [Knowledge](/build/knowledge/create-knowledge), and [Bulk Schedule](/build/agents/give-your-agent-tasks/bulk-schedule).
  </Card>

  <Card title="Automate it on signals" icon="bolt">
    Wrap it in a [workflow](/build/workforces/create-a-workforce) that fires on a [trigger](/build/agents/build-your-agent/triggers).
  </Card>

  <Card title="Let it improve" icon="arrows-rotate">
    Feed opens, clicks, and conversion back into the Agent's [evals](/build/agents/build-your-agent/evals) so drafts track what converts.
  </Card>
</CardGroup>

## Common pitfalls

<AccordionGroup>
  <Accordion title="Sequences that all sound the same" icon="clone">
    Without persona-specific Knowledge, every sequence reads like a watered-down version of the welcome email. Upload distinct persona docs and force the prompt to reference them.
  </Accordion>

  <Accordion title="Trigger drift" icon="route">
    The HubSpot trigger fires on the wrong field and the sequence drafts the wrong campaign. Gate triggers tightly and review what actually causes them to fire in week one.
  </Accordion>

  <Accordion title="Brand-voice regressions" icon="clock-rotate-left">
    A prompt tweak changes tone everywhere. Use [evals](/build/agents/build-your-agent/evals) on a few canonical drafts to catch drift before it ships to subscribers.
  </Accordion>

  <Accordion title="Auto-sending without review" icon="paper-plane">
    Tempting to skip marketing approval and queue directly. Don't — one bad subject line in production costs trust. Gate L3 with a Slack approval until you've watched it run for a quarter.
