Business email on your own domain.

Give your team real mailboxes at yourdomain.com — send and receive, connect any IMAP client (Apple Mail, Thunderbird, mobile) with an app password, and manage it all from one dashboard. No mail server to run.

Why it fits

What you get

Mailboxes on your domain

Addresses at your own domain, aligned with SPF/DKIM so mail authenticates as you — not a mailbox on someone else's consumer domain.

Any IMAP client

Connect Apple Mail, Thunderbird, or a phone with an app password over IMAPS. People use the mail app they already know.

Send and receive in one place

Outbound goes through the same Send API and quota as inbound — one account for the whole mail flow, no second vendor.

Managed from the dashboard

Create mailboxes, issue and revoke app passwords, and watch delivery from one console — no mail server, no per-seat mail host to license.

How it works

Three steps to live

  1. 1

    Verify your domain

    Add MX (inbound) and SPF/DKIM (outbound) records. MailKite checks them and unlocks send + receive for the domain.

  2. 2

    Create mailboxes

    Add the addresses your team needs — you@, sales@, hello@ — from the dashboard. Catch-all is one toggle if you want everything.

  3. 3

    Connect a client

    Generate an app password and sign in from any IMAP client, or use the open-source webmail UI.

Outbound mail is sent through the MailKite Send API

Questions

Is this a replacement for Google Workspace?

For teams that want real mailboxes on their own domain with standard IMAP access and a developer-friendly Send API, it covers the core mail job. It is not a full office suite — there's no calendar or docs; it's email on your domain, managed from a dashboard.

Which mail apps work?

Any that speak IMAPS — Apple Mail, Thunderbird, and mobile mail apps — using the mailbox address and an app password. There's also the MIT-licensed @mailkite/mail webmail UI.

How is outbound sent?

Through the MailKite Send API (or point an SMTP-only app at the SMTP relay). Either way it's aligned to your domain's SPF and DKIM so it authenticates as you.
