Each guide is a complete, runnable recipe — it takes you from nothing to a working outcome by combining SenderKit with the tools you already use (Clerk, Auth.js, Stripe, Supabase, the Vercel AI SDK). They go deeper than the Quickstart and lean on the Core Concepts rather than re-explaining them.

Integrate over raw HTTP

Send and track messages with fetch or curl when you’re not using the SDK.

Send a welcome email on signup

Trigger a welcome email from a Clerk webhook or an Auth.js event.

Recover failed payments & win back churn

Dunning, win-back, and trial-ending emails from Stripe webhooks.

Send team & workspace invites

Invite teammates with a tokenized accept link.

Notify on a database change with Supabase

Email on a row change via a Database Webhook and Edge Function.

Send emails from your AI agent

Give a Vercel AI SDK agent a SenderKit tool.

Add SenderKit from your coding agent

Install the skills plugin for Claude Code, Codex, or Cursor.
