Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
3.0
GPA, above 55 of the 70 other email apps we grade
Mailo is a webmail service run by the French company Mail Object and hosted in France. It bundles a calendar, address book, cloud storage and photo albums with the mailbox, and offers custom domains on paid accounts. A free account shows ads, while Premium removes them and expands storage.
To get you started, here are 9 things to know about Mailo, taken from its own pages and our grades.
A web mailbox with apps, and you connect your own devices over IMAP.

Paid plans start at about $1.68 a month
As its pricing page puts it: €1.50 per month, for a 1 to 5 year term.

The report card

| Subject | Grade | Comment |
|---|---|---|
| Value for money | A | Premium is €1.50 a month, under 60% of the category's cheaper quarter of $3.99. The page doesn't say how that figure is billed, and Premium is sold for 1 to 5 years. |
| Free plan and trial | B | Free with a 1GB mailbox, 500MB of cloud, 5 aliases and IMAP4. One person could live on it, with banner ads. |
| Features | B | Mail with aliases, calendar, contacts, cloud storage, standard protocols and hosting in France. The pages show no gap in the core email work. |
| Ease of use | C | No store rating on record. A web mailbox with apps, and you connect your own devices over IMAP. |
| Platforms and integrations | B | Web, iOS and Android, with OnlyOffice. No desktop app is listed. |
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.

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 Mailo 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.
It is one of the better ones too: its GPA of 3.0 is higher than 55 of the 70 other email apps we grade. It costs $20.11 a year.
What you could make
- Calendar: an app builder makes this well.
What you could not
- An email client: sending, receiving, threading and searching years of mail.
- Storing and serving files for other people.
- A real app for iOS and Android. Something home-made would be a web page.
- The depth: we grade its features B, which means it covers the whole job.
What this rests on. Mailo’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.
