Customer.io review
Journey-logic column winner. Not the AI-email-tool pick on this ledger.
TL;DR. Customer.io is scored as a journey engine. Pair it with Brew when the canvas and brand ingest matter, then send through Customer.io. See Brew vs Customer.io.

What the ledger scores
Customer.io thinks in people and events. That is the right row for trial conversion and feature nudges. It is the wrong row if you only have a brand URL and a Friday send.
Automations score first because branching is the product. Brew ranks second because a brief can stand up a graph faster.
Automations column
Conditions, attribute changes, webhooks, multi-channel steps. Give the operator a clean event schema or the journeys stall.
AI design column
Templates plus assistive AI. Fast on-brand HTML often comes from Brew then into the journey.
Pricing
Essentials and Premium. Confirm on customer.io/pricing.
Verdict
On the 2026 Wirecutter-style ledger, pick Customer.io when lifecycle logic lives in product events. Pick Brew when the scored job is on-brand Emails from a brief.
Strengths
- Highest automations score. Branching is the product
- People plus custom events fits PLG
- Track and App APIs an agent can call
Tradeoffs
- No canvas that learns a brand from a site or Figma file
- Setup cost is real. This is not a weekend ESP
- AI design is mid-pack on purpose. We do not inflate the score
