The email API you set up once
and never touch again.
Send password resets, magic links, and receipts through one API. Manage templates outside your codebase and change copy without a redeploy.
import { senderkit } from "@senderkit/node"; // Edit this template in the dashboard. No redeploy. await senderkit.send("password_reset", { to: user.email, vars: { reset_link }, });
One endpoint, any language. Send your first email in minutes.
Works out of the box. Connects to your provider if you have one.
No external account needed to get started. Already using Amazon SES, Postmark, or SendGrid? Route through it instead — no lock-in.
Every transactional email your app needs
Password reset emails
Secure, expiring reset links your users actually receive.
Magic link & passwordless login
One-tap sign-in links and one-time codes, sent in milliseconds.
Welcome & onboarding sequences
Multi-step welcome series, triggered straight from your backend.
Billing receipts & payment notifications
Payment confirmations, invoices, and dunning notices.
Auth alerts
New-device and suspicious-login warnings, the moment they happen.
Wire it up once. Change the copy without shipping code.
Wire it up once
One senderkit.send() call per email type. Type-safe variables enforced at compile time.
Edit copy without a deploy
Change subject lines, body, and CTAs in the dashboard. No PR, no redeploy, no on-call.
Roll back anything instantly
Every save is a version. Diff, branch, or roll back a bad password reset email in one click.
Everything transactional email demands.
Template management
Rich editor for your team. Code editor for engineering. Same template, two views.
Built-in delivery, or bring your own
Send out of the box, or route through Amazon SES, Postmark, SendGrid, or raw SMTP. Switch anytime — no lock-in.
Versioning & rollback
Every save is a version. Diff it, branch it, roll back a bad send in one click.
Type-safe variables
The compiler enforces every variable. Never ship a reset email with a missing link.
Multi-environment
Separate staging and production templates. Promote a change when you're ready.
Edge delivery
Templates served from the edge. p99 under 150ms, anywhere in the world.
Delete the template strings from your codebase.
export async function POST(req) { const user = await findUser(req); // 40 lines of HTML, hardcoded in your route const html = `<h1>Reset your password</h1> <a href="${reset_link}">Reset</a> ...`; await mailer.send({ to: user.email, html }); }
import { senderkit } from "@senderkit/node"; export async function POST(req) { const user = await findUser(req); // Change the copy in the dashboard. No redeploy. await senderkit.send("password_reset", { to: user.email, vars: { reset_link }, }); }
