Use Sendsets to turn a software product into useful outbound campaigns, then operate mailboxes, warmup, campaigns, replies, and product integrations through the CLI. Use when the user asks to set up or run cold email with Sendsets or wants campaign ideas grounded in their codebase.

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'sendsets' ] || [ -L ~/.agents/skills/'sendsets' ]; then echo 'A skill folder named sendsets already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/hashgraph-online/awesome-codex-plugins' "$d" && git -C "$d" checkout --quiet '6d2e63f73f845eb5dd94c1debba627d4b6e32fba' -- 'plugins/AddisonHoff/sendsets/skills/sendsets' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/AddisonHoff/sendsets/skills/sendsets' ~/.agents/skills/'sendsets' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'sendsets' ~/.claude/skills/'sendsets' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
