Developer-First

Build email into your product. Skip the infrastructure.

Use Mission Inbox APIs, SDKs and webhooks to create inboxes, send email, receive replies and trigger workflows from your existing stack.

Node.js

import { MissionInbox } from 'missioninbox';

const mi = new MissionInbox('mi_xxxxxxxxx');

await mi.emails.send({

from: 'you@yourdomain.com',

to: 'user@example.com',

subject: 'Hello World',

html: '<strong>it works!</strong>'

});

import { MissionInbox } from 'missioninbox'; const mi = new MissionInbox('mi_xxxxxxxxx'); await mi.emails.send({ from: 'you@yourdomain.com', to: 'user@example.com', subject: 'Hello World', html: '<strong>it works!</strong>'
});

Isolated Sending Infrastructure

Everything your application needs to send email

Email API

Send transactional and product email from one REST API.

SMTP support

Connect existing applications and libraries through standard SMTP.

Real-time webhooks

Receive delivery, bounce, open and click events inside your application.

Delivery logs

Inspect message activity and diagnose delivery problems without digging through server logs.

Isolated infrastructure

Keep your sending reputation separate from unrelated senders.

MI Shield

Check email content, headers and sending configuration before messages leave your infrastructure.

Move from your first send to production

Use the same connection as your application grows, with infrastructure designed to keep workloads visible, separated and manageable.

Explore Demo

Separate sending workloads

Keep transactional, product and automated email on clearly defined sending routes.

Protect your reputation

Avoid having unrelated senders determine the reputation behind your emails.

Monitor every send

Follow delivery events and investigate failed or delayed messages.

Scale without rebuilding

Increase sending volume without replacing your application’s email integration.

Isolated Sending Infrastructure

Your sending infrastructure should not depend on someone else’s reputation.

Sales outreach, marketing campaigns and product email should not all depend on the same sending environment. Mission Inbox separates workloads so a problem in one stream does not put another at risk.
