Installation

# From PyPI (latest)
pip install email-cli-tool

# Install a specific version
pip install email-cli-tool==0.2.0

# Upgrade an existing install
pip install --upgrade email-cli-tool

# Or with uv
uv tool install email-cli-tool          # latest
uv tool install email-cli-tool==0.2.0   # specific version

The emailcli skill install command requires version 0.2.0 or newer.

Quick Start

1. Initialize Configuration

emailcli init

Follow the prompts to enter your SMTP settings. Example for Gmail:

2. Send Emails

# Plain text
emailcli send --to user@example.com --subject "Hello" --body "Hello World"

# HTML format
emailcli send --to user@example.com --subject "Notice" \
  --html "<h1>Title</h1><p>Body content</p>"

# With attachments
emailcli send --to user@example.com --subject "Report" \
  --body "Please see attachments" \
  --attach report.pdf \
  --attach photo.png

# Multiple recipients
emailcli send \
  --to a@example.com \
  --to b@example.com \
  --subject "Broadcast" --body "Hello everyone"

# HTML body from file
emailcli send --to user@example.com --subject "Newsletter" \
  --html-file template.html

# Read body from stdin
echo "Content" | emailcli send \
  --to user@example.com --subject "Piped" --body -

3. Wait for Incoming Email

# Block until the next email arrives, print it, then exit
emailcli watch

# Wait up to 5 minutes and save attachments
emailcli watch --timeout 300 --save-attachments ./downloads

Requires IMAP settings — emailcli init asks for them, or add an imap section to the config (see below).

Command Reference

emailcli send

At least one of --body, --html, or --html-file is required.

emailcli watch

Wait for the next incoming email (via IMAP polling), print headers and body to stdout, then exit. Only emails arriving after the command starts are matched; the received email is marked as read.

emailcli init

Interactively create the configuration file at ~/.emailcli/config.yaml.

emailcli config show

Display current configuration (password is masked).

emailcli skill install

Install the send-email agent skill so Claude Code or Codex can send mail for you.

# Install for both Claude Code and Codex (default)
emailcli skill install

# Only one agent
emailcli skill install --target claude
emailcli skill install --target codex

Writes SKILL.md to ~/.claude/skills/send-email/ and/or ~/.codex/skills/send-email/.
