# Build a multi-channel marketing automation platform

Segments, flows, and campaign attribution — one blueprint that covers Klaviyo, Mailchimp, and ActiveCampaign-style automation.

## In brief

- **Category:** Marketing automation
- **Build from:** Modules, workflows, and the page editor
- **Extend with:** Your container when you outgrow the visual tools

## Data model

Build these as [modules and custom fields](../builder-guide/menus-user-types.html)  — no schema migration, no code required to add a field or a relationship:

- Contacts and consent records
- Audience segments
- Custom events
- Campaigns
- Automation flows with wait and branch steps
- Email/SMS templates
- Frequency-limit rules
- Conversion and attribution records

## Pages

Compose these in the [page editor](../builder-guide/page-editor.html)  from data-bound blocks, or start from a template pack and customize from there:

- Segment builder
- Flow designer
- Campaign performance dashboard
- Attribution report

## Automation: an event-triggered automation flow

Model this as a [workflow](../builder-guide/workflows.html)  — each bullet is naturally one step, run automatically on the trigger:

1. A custom event fires (purchase, cart abandonment, signup)
2. The contact enters the matching flow
3. Branching and wait steps execute on schedule
4. Frequency limits are checked before every send
5. Conversions attribute back to the originating campaign

## Market and pricing

Read these as directional

Market sizes and competitor prices move constantly, and published figures vary widely by source and methodology. Treat the numbers below as order-of-magnitude orientation for deciding what to build — not as researched inputs for a pitch deck or a pricing page. Verify current figures before either.

| Segment | Marketing automation |
| --- | --- |
| Market size (directional) | Roughly $6–12B, with pricing conventionally driven by contact list size rather than seats. |
| Who actually buys | E-commerce brands and B2B marketing teams |
| Where incumbents price | Marketing automation platforms scale from about $30/mo at small list sizes into thousands per month at scale. |
| Suggested entry pricing | **$50–500+/mo scaling with contact volume** |

## Building in more value

Where the margin actually lives — the upgrades and add-ons worth designing in from the start rather than bolting on later:

- Contact-volume pricing is the category standard and scales automatically with customer success
- SMS as a metered add-on with margin on every message
- Deliverability tooling and dedicated sending as a premium tier
- Revenue attribution reporting — the feature that justifies the whole spend to a CFO
- Vertical playbook packs (e-commerce, SaaS onboarding, events)

## The BuildWithHQ angle

The platform orchestrates the logic — segments, flows, attribution, frequency limits — while delivery runs through connected providers (SendGrid, Mailgun, Postmark, Amazon SES, Twilio, or others) via [API connections](../builder-guide/external-api-connections.html). You own the intelligence layer; you don't need to become a mail transfer agent to ship it.
