# 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.
