Why teams choose emitd

Lands in the inboxAuthentication and sender reputation are handled for you, so the email your business depends on reaches real people — not the spam folder.

Feels instantReceipts, resets, and alerts go out the moment your users act and arrive in a blink — wherever in the world they happen to be.

Simple and fairLive in five minutes, see everything you send, and pay only for what you send. No seats, no lock-in, no surprises.

Built on Cloudflare Workers and Amazon SES — the request path runs at the edge, the mail goes out over a backbone that has been delivering since 2011. See how we handle your data, the latency benchmarks, or what sending through SES yourself would mean.

Everything the send takes, in one place

More than an email API

The hard parts of email — deliverability, reputation, visibility — are done for you. The parts that make you faster — agents, AI templates, one-click setup — come built in.

Sent from the edge, worldwide

Every message is signed and dispatched from Cloudflare's global network, so receipts, resets, and alerts go out in a blink — close to your users, wherever they are.

Deliverability, handled

Publish SPF, DKIM, and DMARC with one click, let reputation guardrails watch every domain, and have bounces and complaints suppressed automatically — so your mail lands in the inbox.

Built for AI agents

A native MCP endpoint lets agents in Claude, Cursor, or your own tools send email, check deliverability, and look up messages directly — no wrappers, no glue code.

A real developer API

Send in batches of 100, schedule for later, attach files, and retry safely with idempotency keys. Nine SDKs, a CLI, and a sandbox mode mean you go from signup to shipped in an afternoon.

Watch every message

Opens, clicks, bounces, and complaints stream to signed webhooks with automatic retries — and every send is searchable in the console the instant it happens.

Design with AI

Compose on-brand emails from a prompt in the Design Studio, then version and roll back templates in seconds — change a subject line without waiting on a deploy.

Audiences, broadcasts, automations

Import contacts, segment them with a real filter language, send topic-scoped broadcasts, and enroll people in multi-step automations — all through the same API and console.

Receive email, too

Point a domain at emitd and inbound mail lands as parsed messages you can fetch from the API — raw MIME included, up to 25 MB, no separate parsing service.

The console

See exactly what every email did

Not a wall of logs — just the numbers that tell you whether your email landed, updated the instant it happens.

Live delivery healthDelivered, bounced, and flagged — updated the instant it happens, not batched overnight.
Every email, searchableFind any message by person or subject and read its whole story, start to finish.
Reputation at a glanceSimple gauges warn you about a deliverability problem long before it reaches your users.

Give your agents a way to email

emitd speaks the Model Context Protocol — the same standard Claude and Cursor use for tools. Point an agent at https://mcp.emitd.com/mcp with your API key and it gets a full set of email tools, already scoped to your account.

Every API call is a toolsend_email, get_message, preview_template, upsert_contact and the rest of the API — with the API's own fields, so the agent gets them right first time.
Answer its own questionsget_message returns the delivery timeline, so an agent can check whether the email it just sent was delivered, opened, or bounced — and act on the answer.
Only what you allowLimit an agent's key to the features it needs and it sees only those tools. Dry runs, duplicate protection and your quotas apply to every call.

Deliverability

Stop worrying about the inbox

The unglamorous work that decides whether your email lands is handled for you — so you can focus on your product, not your sender reputation.

Trusted sender

Set up to land, not bounce

We walk you through connecting your domain and confirm everything is right, so your email is trusted and arrives where it should.

Always on time

Important mail stays important

Your receipts and resets are kept apart from bulk mail, so a marketing blast can never slow down the email people are actually waiting on.

Effortlessly clean

Bad addresses, handled

Addresses that bounce or complain are set aside automatically — you never re-send to someone who already said no, and your standing stays strong.

Questions

Everything you might be wondering

How do you pronounce emitd?

emitd is pronounced emit-d (/ˌem.ɪtˈdiː/) — like the word "emit" followed by the letter "d". The name comes from transactional messages emitted in milliseconds directly from Cloudflare's edge network.

How is emitd different from sending email myself?

Getting email to reliably reach the inbox means handling authentication, sender reputation, bounces, and monitoring — weeks of unglamorous work. emitd does all of it for you, so you send one request and we take care of the rest.

Will my email actually land in the inbox?

That's the whole point. We set up and manage the reputation and authentication that decide whether your email is trusted, and keep your list clean automatically — so your important messages reach real people, not the spam folder.

How quickly can I start sending?

Minutes. Sign up, create a key, and send your first email with a single call. The free tier is live immediately — no sales call, no waitlist, and no credit card.

What happens when an email bounces or someone complains?

It's handled for you. Those addresses are set aside automatically so you never send to them again — protecting your sender reputation without any work on your part.

Can I use my own domain?

Yes. We guide you through connecting your domain and confirm it's set up correctly, so your email comes from you and is trusted by inbox providers everywhere.

How does pricing work?

The Free plan includes 5,000 emails each month. Pay as you go keeps the first 5,000 free, then bills $0.35 per 1,000. Prepaid Credits cost $0.28 per 1,000 from the first send; each pack is valid for 365 days. There are no paid monthly subscriptions or seat fees.
