Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
2.0
GPA, above 11 of the 122 other email apps we grade
MailMaestro is an AI email assistant from Maestro Labs that writes, replies to, improves and summarizes email inside Outlook and Gmail. Maestro Labs says it acquired Flowrite, the AI email writing division of Flow AI, and folded that business into MailMaestro. Flowrite's own team moved on to Flow AI, a separate product.
To get you started, here are 8 things to know about MailMaestro, taken from its own pages and our grades.
If you want a standalone email app, this isn't one.
- 1
Best for AI replies inside Outlook and Gmail
MailMaestro (the product Flowrite was folded into) writes and rewrites email inside Outlook and Gmail.
- 2
Paid plans start at $12 a month for each person
As its pricing page puts it: $12 per seat / month, billed annually ($15 billed monthly).
- 3
There is a free plan
3 AI requests a week to write, reply to and improve emails, plus templates and text shortcuts.
- 4
AI writing and replies
Writes emails from scratch in several languages, drafts replies from the thread and attachments, and rewrites or polishes selected text.
- 5
Inbox agents
On Pro, agents label incoming mail, prepare drafts before an email is opened and send follow-ups when someone has not replied.
- 6
Summaries
Summarizes long emails and threads. Summarizing attachments and asking questions about the inbox are marked as Outlook features.
- 7
A 2.0 GPA, above 11 of 122
That is against the other email apps we grade, on value, the free plan, features, ease of use and platforms.
- 8
Keep it
To replace MailMaestro 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 AI replies inside Outlook and Gmail
MailMaestro (the product Flowrite was folded into) writes and rewrites email inside Outlook and Gmail. The free plan stops at 3 AI requests a week, the inbox agents and unlimited use need Pro at $12 a seat, and annual plans aren't refundable. If you want a standalone email app, this isn't one.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | C | Pro is $12 a seat a month on annual billing ($15 monthly), which sits near the dear end of email tools: the middle is about $8 and the cheaper quarter starts at $3. |
| Free plan and trial | C | Free forever with no card, but only 3 AI requests a week. That's a taste, not a plan you can work on. The Pro trial is 14 days. |
| Features | C | Writes, replies, rewrites and summarizes, with templates and shortcuts. It lives inside Outlook and Gmail, and the listing shows no standalone client. |
| Ease of use | C | No store rating on record. You add it to your mailbox and connect your account, then learn the templates and shortcuts. |
| Platforms and integrations | C | A browser and Outlook add-in for one job, with Teams, Zoom and Google Meet listed. No phone or desktop app of its own. |
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 MailMaestro is for
- Fits if you answer lots of similar emails in Outlook or Gmail
- Works for teams that want shared templates and one bill, from two seats up
Who it is not for
- Tight if you stay free: 3 AI requests a week runs out by Tuesday
- Pricey if you want inbox agents, labels and follow-ups, which are Pro-only at $12 a seat
- Skip it if you want a full email client, as it only adds to Outlook and Gmail
- Watch out: annual plans can't be refunded after purchase, according to the pricing FAQ
- Watch out: the name is in flux, as Flowrite was folded into MailMaestro and its old team moved to a separate product

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 MailMaestro 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: 94 of the 122 other email apps grade higher. It costs $144 a year.
What you could make
- Templates: an app builder makes this well.
What you could not
- An email client: sending, receiving, threading and searching years of mail.
- Filters that read every message as it arrives.
- Text expansion that works in every app.
- It is priced for each person, which means accounts and billing for a team.
- It plugs into other products, Outlook, Gmail and Microsoft Teams among them.
- AI features, unless you pay a model provider for each request yourself.
What this rests on. MailMaestro’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.
