## where subscriber.dev is different

› sending more doesn't cost more

Brevo's price climbs with every email. Ours depends only on how many people you email, so a busier onboarding sequence costs nothing extra on a paid plan.

› automation on every plan

Workflows, triggers and exit conditions are on the free plan. Brevo needs Standard for automation.

› built for agents and terminals

Everything works over MCP, the API, a CLI and a TUI, so there's no dashboard to learn.

› open source

AGPL-3.0 and self-hostable with Docker Compose, so you're never locked in.

## when Brevo is the better fit

  • You have a big list you email rarely, where unlimited contacts win.
  • You want SMS, WhatsApp, live chat and a CRM in the same tool.
  • A marketing team wants a drag-and-drop editor and landing pages.

## switching

Import your contacts through the bulk API or the CLI, 500 at a time, or hand your agent a Brevo export. Describe your automations and it can rebuild them as workflows, with Stripe events as triggers and exit conditions.
