Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
2.8
GPA, above 36 of the 51 other email apps we grade
Marco is an email client for macOS, iOS and the web that brings Gmail, Outlook, Yahoo, iCloud and other IMAP accounts into one inbox. It is built offline-first, syncing mail to the device so it can be read, searched and written without a connection, and it deliberately leaves out AI drafting, summaries and replies. Marco Technology Inc. offers it free, with a paid Pro plan announced but not yet available.
To get you started, here are 8 things to know about Marco, taken from its own pages and our grades.
It leaves out AI on purpose, so nothing drafts, sums up or replies for you.
- 1
Best for free offline email with no AI in it
Marco is a free email app for Mac, iPhone and the web that takes all your accounts into one inbox and keeps working with no internet.
- 2
It is free
Marco has no paid plan at all. Free forever with no credit card: unlimited email accounts, offline access, cross-platform sync, smart search, and custom labels and filters. A Pro plan is marked Coming Soon.
- 3
It runs on 3 platforms
macOS, iOS and Web.
- 4
One inbox for every account
Connects Gmail, Outlook, Yahoo Mail, iCloud Mail and any provider that supports IMAP, with no limit on the number of accounts managed from a single inbox.
- 5
Offline-first
Emails are synced to the device, so you can read, search, compose and organize without an internet connection. Changes sync automatically once you reconnect.
- 6
No AI writing
Marco does not generate, rewrite, summarize or reply to email with AI. The company presents this as a deliberate choice to keep email a conversation between people.
- 7
A 2.8 GPA, above 36 of 51
That is against the other email apps we grade, on value, the free plan, features, ease of use and platforms.
- 8
Keep it
Marco is free, so making your own would save you nothing.

The report card
Best for free offline email with no AI in it
Marco is a free email app for Mac, iPhone and the web that takes all your accounts into one inbox and keeps working with no internet. It leaves out AI on purpose, so nothing drafts, sums up or replies for you. The feature list is short, with no calendar, snooze or send later on record, there are no Windows or Android apps yet, and the Pro plan with custom domains and team features is still marked Coming Soon with no price.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | A | It's free: unlimited email accounts, offline access, sync across devices, search, and custom labels and filters, all at $0 with no payment method needed. A Pro plan is marked Coming Soon with no price. |
| Free plan and trial | A | Free forever with no credit card, and nothing is held back: unlimited email accounts, offline access, cross-platform sync, search, labels and filters. There's no paid plan to buy yet. |
| Features | C | The basics, and that's where the list stops: one inbox for Gmail, Outlook, Yahoo, iCloud and any IMAP account, mail synced to the device for offline use, search, labels and filters. No AI by design, and no calendar, snooze or send later on record either. |
| Ease of use | C | No rating on record. There's little to it, but you're still connecting each account yourself, and with no AI and a short feature list there's nothing to guide you once you're in. |
| Platforms and integrations | C | Apple and a browser: Mac, iPhone and iPad apps plus a web version, with sync between them. No Windows or Android apps, though the FAQ puts both on the roadmap, and API access sits in the Pro plan that isn't out yet. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who Marco is for
- Fits if you want an email app that doesn't write or summarize your messages for you
- Works for people who need their mail on a plane with no connection
Who it is not for
- Skip it if you're on Windows or Android, as those apps are only on the roadmap
- Not for you if you want AI drafts or summaries, because it leaves them out on purpose
- Too light for teams, since team collaboration sits in a Pro plan that's still Coming Soon
- Not for you if you need snooze, send later or a calendar, as none is on record
- Watch out: custom domains, priority support and API access wait for the unpriced Pro plan
Good to know
Good for
- People who want an email client without AI writing features
- Travelers and others who need full access to mail offline
- Apple users with accounts spread across Gmail, Outlook, Yahoo and iCloud
Worth knowing
- There are no Windows or Android apps; the FAQ says both are on the roadmap.
- It has no AI features by design, so there are no drafts, summaries or automatic replies.
- The Pro plan, listing priority support, custom domains, team collaboration and API access, is marked Coming Soon with no price.

Part 04 · Standing
Where it stands
Its grades against its category, and whether to keep it or make your own
36/51
Other email apps it is graded above
Marco's GPA of 2.8 is higher than 36 of the 51 other email apps we grade, and level with 4.
It stands best on free plan and trial (A, above 42 of 51) and worst on features (C, above 0).
Marco has no paid plan.
On features, ease of use and platforms it scores 2.0 out of 4. Nothing scores higher for less, though at least one tool matches that score at a lower price.
Each grade against the category
Every bar is all 52 email apps we grade, cut by the letter each got. Marco’s own letter is outlined.

Price against what you get
Each dot is one of 50 email apps. Further left costs less; higher up scores better on features, ease of use and platforms. Marco is the marked dot.
What paid plans start at, a month (each step along is roughly double) →
Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
Keep it
Marco is free, so making your own would save you nothing.
And it is not the kind of software a weekend replaces. It is one of the better ones too: its GPA of 2.8 is higher than 36 of the 51 other email apps we grade.
What you could not
- An email client: sending, receiving, threading and searching years of mail.
- Apps for macOS and iOS that stay in step with each other.
What this rests on. Marco’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
