SenderKit
SenderKitを使うと、ChatGPTやCodexから直接、取引系およびマーケティング系のメッセージ（メール、SMS、プッシュ、ウェブプッシュ）を構築・実行できます。メッセージテンプレートの作成・管理、ウェルカムメール、OTPコード、領収書の送信、各メッセージの配信状況の監視、予定送信のキャンセル、受信メールアドレスとドメインの管理が可能です。Codexでは、バンドルされたスキルがSenderKitをコードベースに統合します。通知フローの追加、SDKの統合、メール配信性やDNS認証の診断が行えます。
ドキュメント
SenderKit
Transactional notifications that live in a dashboard, not your codebase.
Your transactional templates — welcome emails, password resets, billing notices — usually live in your repo as React Email components, MJML, or string literals scattered across route handlers. Every copy tweak becomes a pull request, a redeploy, and a developer in the loop. SenderKit moves the template out of the codebase and into a dashboard with versioning and environments. You integrate the send call once; after that, changing the wording never touches your code.
Who it's for
Solo founders and teams of five or fewer shipping modern web apps — Next.js, Clerk or Auth.js, Stripe, Supabase or Neon. Teams that ship in days, not months, and don't want a notification system to babysit. If your designer, support lead, or non-technical co-founder should be able to fix a typo in the welcome email without opening an editor, SenderKit is for you.
Go from zero to your first send in under five minutes. Create an API key and authenticate requests with a Bearer token. Install@senderkit/sdk and call send().
The raw REST contract behind every SDK and the CLI.
