Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
2.0
GPA, above 2 of the 51 other email apps we grade
Mimestream is a native macOS email client made specifically for Gmail. Because it talks to the Gmail API, features such as inbox categories, colored labels, server-side filters and Gmail search work inside a Mac app with system notifications, keyboard shortcuts and swipe gestures. It is sold as a subscription per person or per seat, and the vendor says data and tokens are stored only on your device.
To get you started, here are 9 things to know about Mimestream, taken from its own pages and our grades.
No rating on record, and nothing to set up: if you know Gmail and you know a Mac, you already know this.
- 1
Best for Gmail as a native Mac app
Mimestream is a Mac app for Gmail that talks to Gmail directly, so your categories, colored labels, filters and Gmail search work the way they do on the web, with Mac notifications, shortcuts and swipes.

Gmail features in a Mac app
Powered by the Gmail API, so inbox categories, color-coded labels and Gmail-backed search behave the way they do in Gmail.
- 6
Server-side filters and vacation replies
Create and edit Gmail filters and vacation responses from inside the app instead of going to Gmail's web settings.
- 7
Multiple accounts and unified inbox
Add all of your Gmail accounts, combine them in an optional unified inbox and send from any configured Gmail alias.
- 8
A 2.0 GPA, above 2 of 51
That is against the other email apps we grade, on value, the free plan, features, ease of use and platforms.
- 9
Keep it
To replace Mimestream you would be making an email client: sending, receiving, threading and searching years of mail. That is not a weekend's work, with an AI app builder or without one.

The report card
Best for Gmail as a native Mac app
Mimestream is a Mac app for Gmail that talks to Gmail directly, so your categories, colored labels, filters and Gmail search work the way they do on the web, with Mac notifications, shortcuts and swipes. It's $49.99 a year, and a family can share one license. It's Mac only and Gmail only, there's no one-time purchase, the app stops without an active subscription, and monthly plans can't be refunded.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | C | $49.99 a year works out at $4.17 a month, in the middle band for this category rather than its lowest-priced quarter, and it covers all your Google accounts on 5 devices, with family in the same household sharing free. Pay monthly and it's $4.99, and there's no one-time purchase at all. |
| Free plan and trial | C | No free plan. The trial is 14 days, fully functional, with no credit card required. After that an active subscription is required to keep using the app. Annual plans can be refunded within 30 days. |
| Features | C | It does its one job: Gmail on a Mac, with inbox categories, colored labels and Gmail search behaving as they do on the web, server-side filters and vacation replies editable in the app, plus a unified inbox, templates, snooze, undo send and tracker blocking. That's a narrower job than a mail client's. |
| Ease of use | B | No rating on record, and nothing to set up: if you know Gmail and you know a Mac, you already know this. Your own labels and categories come across, with system notifications, keyboard shortcuts and swipe gestures on top. |
| Platforms and integrations | D | One operating system. macOS 12 Monterey or newer, with no iOS, Windows or web version listed, and it's built for Gmail accounts with no mention of other providers. Beyond Gmail the only tie-in on record is Apple Contacts. |
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 Mimestream is for
- Fits if you're on a Mac and your email lives in Gmail or Google Workspace
- Works for households, since an Individual license can be shared with immediate family
Who it is not for
- Skip it if you want the same app on your iPhone or a PC, as it's Mac only
- Not for you if any of your mail is Outlook or iCloud, because it's built for Gmail accounts
- Pricey if you pay monthly, at $4.99 a month against $49.99 for the whole year, and monthly plans aren't refundable
- Watch out: there's no one-time purchase, and the app stops working without an active subscription
- Tight if your Mac is older, as it needs macOS 12 Monterey or newer

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
To replace Mimestream you would be making an email client: sending, receiving, threading and searching years of mail. That is not a weekend's work, with an AI app builder or without one.
That makes this kind of software worth paying for, not this one in particular: 43 of the 51 other email apps grade higher. It costs $49.99 a year.
What you could make
- Templates and Markdown: an app builder makes these well.
What you could not
- An email client: sending, receiving, threading and searching years of mail.
- A real app for macOS. Something home-made would be a web page.
What this rests on. Mimestream’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.
