Certified Customer.io partner agency
Product-led SaaS and consumer brands with technical marketing teams who want a workflow-first lifecycle platform with deep developer surfaces.
What we ship on Customer.io
Capabilities.
Production-grade Customer.io work, not theoretical knowledge. Each line below maps to programs we've shipped — across the platform's actual surface area, not the marketing site's.
Implementation
Workflow architecture.
Triggered, scheduled, and broadcast Workflows orchestrated across email, SMS, push, in-app, and webhook channels with attribute-based branching.
Personalization
Liquid + Collections.
Liquid templating with Collections-based dynamic content. Webhook steps for live API personalization.
AI
LLM Actions + Claude Cowork.
Native LLM Action steps inside Workflows. Claude Cowork integration for AI-assisted marketing operations (the Anthropic partnership).
Data
Data Pipelines (CDP).
Customer.io's CDP product — events, profiles, traits, integrations. Wired to Snowflake, BigQuery, or Segment depending on source.
Objects model
Multi-entity relationships.
Beyond person-level: workspace, account, order, subscription. Multi-entity targeting for B2B SaaS and complex consumer products.
Migration
Iterable / legacy → Customer.io.
Migrations from legacy ESPs into Customer.io with event taxonomy mapped, Workflows rebuilt, and Collections populated from your warehouse.

FAQ
Questions we hear.
Is BRCG a certified Customer.io partner?
Yes. BRCG is a certified Customer.io partner agency. We have shipped Customer.io programs for SaaS and product-led consumer brands where technical marketing teams need deep developer surfaces.
How long does a Customer.io implementation take?
A greenfield Customer.io implementation typically takes 6–10 weeks: 1–2 weeks for attribute model + Objects setup, 3–5 weeks for Workflow builds, 2–3 weeks for Data Pipelines wired up. Migrations from Iterable, Mailchimp, or HubSpot add 3–5 weeks.
What's the difference between Customer.io and Iterable?
Customer.io is more workflow-first and developer-friendly with deeper webhook and API surfaces. Iterable has stronger native cross-channel orchestration (especially embedded messaging) and aggregate reporting. Both are certified BRCG partners — we'll tell you honestly which fits.
Does BRCG implement LLM Actions and Claude Cowork?
Yes. BRCG implements Customer.io's native LLM Action workflow steps and the Claude Cowork integration (the Anthropic partnership). We use them for content generation, decisioning, and AI-assisted marketing ops.
What size companies work best on Customer.io?
Customer.io fits SaaS and product-led consumer brands from Series A through Series C with technical marketing teams. Above ~$100M ARR with enterprise multi-channel orchestration needs, Braze or Iterable usually fit better. Below Series A, the workflow complexity is often overkill.
