From Mango Zest

Mail for people who work across several companies.

If you hold a mailbox at six companies, every mail product you have used treats you as six unrelated users. Six sign-ins, six inboxes, six chances to reply to one client from another company’s address.

This is built the other way round: one person, every mailbox, and a colour on every row so you always know which company you are speaking as.

Self-hosted or run by us. No per-seat pricing, and no send limit you find out about afterwards.

The problem

Every mail product treats you as several unrelated users.

  • Six sign-insOne
  • Six inboxesOne list, colour on every row
  • Six chances to reply as the wrong companyThe send button wears the company’s colour

If you run a venture studio, an agency or a group of companies, you probably hold accounts at five or six of them. Per-seat mail charges per company, so twelve companies cost twelve times as much however little each one sends.

Worse, none of it knows the same human is behind every account. You sign out and back in. You keep separate browser profiles. You forward everything to one inbox and then reply from the wrong address in front of a client.

That is the problem CanopyMail is built around — not as a feature, as the shape of the product.

What is in it

Mail, calendar, contacts. Nothing else.

It is mail — not a suite. Six things it does differently, each drawn below from the same colours and type as the product itself.

One switch, not one login

Every mailbox you hold is already open. Switching company is a keystroke, not a sign-in, and the colour of the company you are acting as is on every screen you touch — including the send button.

Send limits in plain numbers

There is a limit. It is a number, it is in your console next to what you have used, and importing mail never counts against it.

Search that crosses companies

One query over every mailbox you can open, with real operators. No other mail product can do this, because no other one knows the mailboxes are all yours.

Admins who cannot see each other

Each company administers itself. Reading a mailbox needs an explicit grant, it is written to the audit log, and the owner is told — not configurable off.

A migration that shows its working

Folder by folder: what the old system said was there, and what arrived. Where something is deliberately not copied, the report says so.

Calendar and contacts, included

Every company’s calendar in one week, coloured the same way as its mail. Standards-based, so Apple Mail, Outlook and Thunderbird connect with an app password and nothing else.

Honest comparison

Where we are better, and where we are not.

Gmail has more features than we do, and Google’s spam filtering operates at a scale we will never match. We are not trying to win on either.

About send limits, since everyone buries this

There is an outbound limit, and you can see it in your console next to how much you have used. It exists because everyone on a shared sending pool shares its reputation — one compromised account sending bulk mail would hurt delivery for every company on it.

What we will not do is advertise “unlimited” and let you discover a fifty-message ceiling after you have migrated. Importing your existing mail is never limited by it.

How the limit works

Bring your mail with you, and take it away again.

Importing keeps your folders, your flags and the dates your mail actually arrived — and produces a report saying, folder by folder, what the old system said was there and what arrived.

Leaving produces mbox, iCalendar and vCard files that open in Thunderbird, Apple Mail and every migration tool. Nothing in the archive is in a CanopyMail format.

550 · 5.7.1PolicyRefused by the receiving server

The receiver rejected the message on policy grounds.

Likely causes

  • Classified as spam
  • Your sending IP is on a blocklist
  • SPF or DKIM failed, or DMARC alignment failed
  • Recipient rules reject external senders

What to do

  1. Check your DMARC reports for this domain
  2. Check the sending IP is not on a major blocklist
  3. Confirm the From domain aligns with the DKIM signing domain

One person. Every company. One inbox.

Priced on data, not on people — storage and volume, never per seat. Your eighth company is not your eighth bill.
