Sendblue CLI

Overview

@sendblue/cli is a Node CLI that creates a Sendblue account, provisions an iMessage-enabled number, and sends messages. It is the fastest way to text from a shell, script, or Claude Code hook — no API client, no webhook server, no credentials in env vars. Credentials live at ~/.sendblue/credentials.json (mode 600) and Node.js 18+ is required.

When to Use This Skill

Use when the user wants to text a phone number from a script, shell, hook, or agent turn (e.g. "text me when X finishes", "ping my phone", "notify on completion").
Use when the user mentions sendblue as a CLI/binary or asks to set up the @sendblue/cli package.
Prefer this skill over [[sendblue-api]] when the work happens in a shell context, one-shot script, cron job, or agent hook.
Reach for [[sendblue-api]] instead when writing application code that integrates Sendblue, receiving inbound webhooks, or needing features the CLI does not expose (send styles, reactions, group messages, status callbacks, media uploads).

How It Works

Step 1: Install

npm install -g @sendblue/cli       # global, exposes `sendblue`
# or one-shot:
npx @sendblue/cli <command>

Step 2: Set up an account

sendblue setup runs interactively by default. For CI/scripts, run it in two phases — the first call sends an 8-digit verification code by email, the second consumes it.

sendblue setup --email [email protected]                                       # sends code
sendblue setup --email [email protected] --code 12345678 \
               --company my-co --contact +15551234567                        # completes setup

Flag	Notes
`--email`	Email address
`--code`	8-digit verification code (from the email)
`--company`	Lowercase, hyphens/underscores, 3–64 chars
`--contact`	First contact, E.164
