Mail System
Business email on your own domain, and nothing you did not ask for. The Mail System does one job — getting your messages in, out and trusted — on a mail server we wrote and run ourselves. Start free in the browser, or open it up to every mail app your team already uses for a few dollars an account.

Mail, done properly
Your name on every address.
A business that writes to customers from a free consumer address is asking them to take it on trust. A business that runs its own mail on a neglected server finds out the hard way that its invoices have been landing in spam for a month.
The Mail System sits between those two. Every address is on your own domain. Every outbound message is signed so receiving servers can check it really came from you. And the whole product is deliberately narrow: webmail, SMTP, IMAP and POP3 — no bundled calendars, contacts or office suite you are paying for and not using.
Your own domain
[email protected] from day one, on the free plan as well as the paid one.
Signed outbound mail
Every message leaves with a DKIM signature, so Gmail, Outlook and the rest can verify the sender.
Encrypted connections
Mail apps connect to SMTP, IMAP and POP3 over TLS, so passwords and messages never cross the network in the clear.
Built for deliverability
Outbound mail takes a relay path chosen to reach the inbox, and we help you publish SPF, DKIM and DMARC correctly.
Our own mail server
The SMTP engine is written in-house on Java and Netty, so when something needs fixing we fix it rather than file a ticket.
Mail and nothing else
No calendars, no contacts, no bundled suite. You pay for email, and email is what you get.
Plans
Two plans. Pick per account.
Keep shared inboxes and occasional users on the free plan, and give full access to the people who live in a desktop or mobile mail app.
Paid
USD 3 / account / month
Everything in Free, plus access from any desktop or mobile mail app you already use.
- Webmail in any modern browser
- SMTP for sending from mail apps and your own applications
- IMAP for mailboxes kept in sync across devices
- POP3 for downloading mail to a single computer
- Addresses on your own domain name
Architecture
In, out and trusted.
Your users reach their mailbox the way they prefer; the Mail System receives, signs and delivers on your domain.
Client compatibility
Your team keeps the mail app it already knows.
On the paid plan the Mail System speaks standard SMTP, IMAP and POP3, so any mainstream mail app connects with the usual server settings.
| Client | Platform | Notes |
|---|---|---|
| Webmail | Any modern browser | Included on both plans; nothing to install |
| Outlook | Windows, macOS | IMAP or POP3 for incoming, SMTP for outgoing |
| Apple Mail | macOS, iOS | Standard IMAP account with SMTP sending |
| Thunderbird | Windows, macOS, Linux | IMAP or POP3 with SMTP sending |
| Android and Gmail app | Android, iOS | Add as an other or IMAP account |
| Your application | Any platform | Send transactional mail through authenticated SMTP |
Protocols
Which one do I need?
Most teams want IMAP. The others are there for the cases where they are the right answer.
Webmail
Read and send from any browser, with nothing to configure. Included on the free plan.
IMAP
Mail stays on the server and stays in sync — read on your phone, it shows as read on your laptop.
POP3
Download mail to one computer and keep it there, for the people who work that way.
SMTP
Send from any mail app, or from your own software, printers and scanners.
