What's inside
Every email tool your team actually needs. Nothing they don't.
Replace four separate vendors — transactional API, marketing tool, deliverability monitor, and domain wizard — with one platform that's cheaper than any of them individually.
Transactional API that just works
Resend-style JSON API with idempotency, scheduling, tags, and webhooks. Typed SDKs for Node, Python, Go, and PHP. Clear error codes, zero magic.
Lightweight marketing
Block-based templates with {{variables}}, reusable snippets, and live preview. Lists, segments, and automation workflows that stay simple.
Built-in deliverability
Monitor reputation, seed tests, DMARC rollout, and domain warmup from inside the product. Get paged when complaint rates drift.
Cloudflare-first, fast everywhere
API and dashboard run on Cloudflare Workers and Pages. Global latency under 50 ms p50. Free CDN for images and tracking assets.
Integrations out of the box
Webhooks, Zapier, Make, FormlyIQ, WordPress plugin, Canva and Figma template import. Keep your stack.
Contacts, suppressions, compliance
Bounces, complaints, unsubscribes, and one-click list-unsubscribe handled automatically. GDPR-ready with data export and deletion.
AI-powered docs search
Ask a question in plain English inside the docs or the dashboard. Answers cite the exact doc section.
Fair, predictable pricing
A generous free tier, simple per-email pricing above that. Dedicated IPs available as a cheap add-on. No seat fees.
How it works
From zero to first email in under five minutes.
01
Add a domain
Paste your domain. We publish DKIM and MAIL FROM records for you — or hand you exactly what to add if your DNS lives elsewhere.
02
Ship code or send a campaign
Call POST /v1/emails from your app, or compose a block-based template and blast it to a list. Same platform, same logs.
03
Watch deliverability in real time
See every bounce, open, click, and complaint on one timeline. Suppressions and unsubscribes are handled automatically.
POST /v1/emails Node.js SDK cURL 200 OK · 48ms
const resp = await sushi.emails.send({
from: 'hello@acme.com',

tags: ['onboarding'],
})

Teams that switched
Fewer tools. Better email. Happier teams.
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.

FAQ
Questions we hear a lot.
Who is SushiSend for?
Developers, SaaS founders, agencies, and marketing teams who want one platform for both transactional and marketing email. If you currently juggle Resend plus Mailchimp, or are eyeing Customer.io but dreading the price tag, you're our target user.
How is this different from Resend?
Resend is a great transactional API. SushiSend does everything Resend does and adds marketing campaigns, automation workflows, built-in deliverability monitoring, and automatic domain setup when your DNS is on Cloudflare.
Do you offer a free tier?
Yes — 3,000 emails per month on one sending domain, forever, no credit card. That's enough to power a real product with transactional email.
Is my data private?
Yes. We don't train models on your emails. Your contacts, content, and logs are isolated to your workspace. We're GDPR-ready with data export and deletion endpoints.
Which DNS providers are supported for automatic setup?
Cloudflare is fully automated today. For other providers we give you exact records to copy-paste and verify in the dashboard. Route 53, Namecheap, and GoDaddy automation are on the roadmap.
Can I use a dedicated IP?
Yes — available as a $79/month add-on on Pro and Scale. We handle warmup and pool management automatically.
What about high-volume senders?
Scale plans and custom enterprise agreements go into the millions of emails per month. Dedicated IPs, SSO, audit logs, and SLA-backed support included.
How does pricing work above the plan limits?
Overage is billed at $0.75 per 1,000 emails on Pro and $0.50 per 1,000 on Scale — the cheapest in the category. No overage charges on the free tier; we just queue and throttle.
Can I cancel anytime?
Yes, monthly plans cancel instantly. No contracts, no ghost seats, no re-activation fees.
Is SushiSend open source?
The SDKs, the WordPress plugin, and several core packages are open source on GitHub. The dashboard and sending infrastructure are proprietary — but the platform is built on open standards so you can migrate out if you ever need to.
