## where subscriber.dev is different

› less than half the price

$39 a month for 10,000 subscribers against $99, and the gap holds at every tier.

› your provider, your reputation

Send through Resend, Postmark, Amazon SES, Cloudflare or any SMTP server. Your domain's reputation is yours, and you pay them directly.

› open source

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

› a TUI as well as a CLI

Watch runs, send broadcasts and manage workflows from a full terminal UI.

## when Loops is the better fit

  • You'd rather not set up an email provider at all.
  • You want to design emails in a visual editor with ready-made templates.
  • You want transactional email, like receipts and password resets, through a dedicated API in the same tool.

## switching

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

# from your terminal
$ npx @subscriber.dev/cli login
# from your agent
