Automatic domain onboarding
Paste your domain. SushiSend publishes DKIM, SPF, and MAIL FROM records automatically when your DNS is on Cloudflare — and gives step-by-step instructions everywhere else.
SushiSend combines a developer-grade transactional API, lightweight marketing automation, and automatic domain onboarding into one modern platform. Built on Cloudflare and Amazon SES so delivery is fast, durable, and affordable.
Replace four separate vendors — transactional API, marketing tool, deliverability monitor, and domain wizard — with one platform that's cheaper than any of them individually.
Paste your domain. SushiSend publishes DKIM, SPF, and MAIL FROM records automatically when your DNS is on Cloudflare — and gives step-by-step instructions everywhere else.
Resend-style JSON API with idempotency, scheduling, tags, and webhooks. Typed SDKs for Node, Python, Go, and PHP. Clear error codes, zero magic.
Block-based templates with {{variables}}, reusable snippets, and live preview. Lists, segments, and automation workflows that stay simple.
Monitor reputation, seed tests, DMARC rollout, and domain warmup from inside the product. Get paged when complaint rates drift.
API and dashboard run on Cloudflare Workers and Pages. Global latency under 50 ms p50. Free CDN for images and tracking assets.
Webhooks, Zapier, Make, FormlyIQ, WordPress plugin, Canva and Figma template import. Keep your stack.
Bounces, complaints, unsubscribes, and one-click list-unsubscribe handled automatically. GDPR-ready with data export and deletion.
Ask a question in plain English inside the docs or the dashboard. Answers cite the exact doc section.
A generous free tier, simple per-email pricing above that. Dedicated IPs available as a cheap add-on. No seat fees.
Paste your domain. We publish DKIM and MAIL FROM records for you — or hand you exactly what to add if your DNS lives elsewhere.
Call POST /v1/emails from your app, or compose a block-based template and blast it to a list. Same platform, same logs.
See every bounce, open, click, and complaint on one timeline. Suppressions and unsubscribes are handled automatically.
const resp = await sushi.emails.send({
from: 'hello@acme.com',
to: 'user@example.com',
subject: 'Welcome to Acme',
template: 'welcome',
variables: { name: 'Penelope' },
tags: ['onboarding'],
})
// resp.id = 'em_01HRY3Z7Q9M7'
// resp.status = 'queued' Transactional, marketing, lifecycle, and multi-tenant infrastructure in the same dashboard and API.
One API call. Automatic retries, idempotency, webhooks, deliverability monitoring. Use it for password resets, order confirmations, magic-link auth, and daily digests.
Block-based templates, A/B subject lines, list targeting, scheduled sends. Your marketing team moves without pinging engineering for every tweak.
Trigger multi-step flows on user events. Welcome series, trial reminders, churn saves — without a CDP contract.
White-label domain setup for your own customers. Issue scoped API keys, isolate workspaces, and bill on usage.
The other platforms do one job well. SushiSend does all of them — cheaper, faster, and without the migration tax.

Accurate as of April 2026. Details matter — we'll keep this table honest; tell us if anything looks off.
We replaced three tools with SushiSend and cut our email bill by 40%. The domain wizard alone saved our ops team a day of back-and-forth with DNS.
The transactional API feels like Resend, the marketing side feels like Customer.io, and the dashboard is faster than both. Our devs and marketers are finally happy at the same time.
Deliverability instrumentation out of the box was the killer feature. We caught a reputation dip on day three and fixed it before it became a problem.
I set up a sending domain, pushed a welcome email template, and fired my first POST /v1/emails in eleven minutes. That included making coffee.
Simple pricing with no seat fees changed the math for us. We can bring the whole support team in without our CFO screaming.
The AI docs search quietly replaced half of our customer-support tickets. When it does escalate, the reply already cites the exact setting.
