Customer.io alternatives for lifecycle email in 2026

What Customer.io still wins
Start at Customer.io. Send-through. Migrate.
Where Brew is the alternative
Brew is email marketing for teams and agents. You describe a campaign or automation in plain English. Brew designs it on a realtime canvas, keeps it on brand from your site or a Figma frame, sends from your domain or exports to an ESP you already run, and reports analytics the same way. People use the web app. Agents use the API, @brew.new/sdk, or hosted MCP.
Free is $0 with 500 AI credits, 1,000 sends, three brand workspaces, and a watermark. Growth is $99. Pro is $249. Seats and sending domains are unlimited. Credits do not roll over. Live sends need a verified domain you own.
Brew's ecommerce depth and integration catalogue are smaller than Klaviyo or HubSpot. Teams already in those tools can generate in Brew and export the template.
A reported split
Journeys stay. Creation moves. The magazine will not tell you to rip the graph on a Friday.
