Migadu Arabic: 0 of the 2 places we could read

The companies, one by one

We read every one of these companies’ own pages: the pricing page, the cart, the refund terms, the support page. What follows is not a summary of what a company says about itself, it is what we found written there and what we did not find. The order is the order of the scores, and the card under each name redoes the arithmetic in front of you.

Proton Mail

A full privacy bundle, and a page with no contact channel

4.5Poor

Encryption, a company under Swiss law, and a bundle carrying storage, a VPN and a password manager: an offer with few equals for anyone who wants it. The flaw is that the sales page names no support channel and no hours, and Arabic is entirely absent from its pages.

30-day money-back guarantee

What their page says · proton.me

And what it does not say: No contact channel and no hours on the pricing page, only buttons for sales and a demo. And no renewal price.

The price is $34.95 a month for a team of five mailboxes billed yearly, higher month to month. With it comes storage, a document editor, a VPN, a password manager and meetings.

The page opens on yearly billing by default and prints beneath the card what is charged every twelve months. The 30 days money-back guarantee is printed beneath the cards.

No Arabic language tag and no language switcher, only a currency control offering three currencies. The product is built for a reader who reads English.

In its favour

  • A refund window of 30 days
  • What you get: 7 of the 8 capabilities we could read

Against it

  • Arabic: 0 of the 2 places we could read
  • No published support hours
  • Suits: A team working in English that puts privacy first.
  • Does not suit: A team writing in Arabic that needs support in its own language.

Not yet measured: speed, uptime, support reply time, the control panel, and a refund actually claimed. Those five need a bought plan and a measurement round, and none of them is in the score today.

The price on the card is not what you will pay

4.5Poor

Mail under German law, data inside Europe and security certifications published by name; anyone who needs that knows why. The flaw is that a business account needs a monthly service package above the per-mailbox price that the card never mentions, and the entry mailbox is tight.

What their page says · mailbox.org

And what it does not say: The page does not add the mailbox price and the service package into one figure, so a buyer reads two tables to learn their own cost.

The price is $32.61 a month for a team of five mailboxes, a long way from what the card shows. There is no annual contract, and billing runs on credit you load onto the account.

The entry tier is two gigabytes of mail with no file storage, and extra capacity is sold by the gigabyte at a price the company publishes for each tier.

The language switcher offers German and English alone, with no Arabic in the support pages. A German company selling into a European market, and it says so plainly.

In its favour

  • A free trial of 30 days
  • A narrow premium for paying monthly
  • No commitment term

Against it

  • Arabic: 0 of the 2 places we could read
  • A mailbox of 2 GB
  • Suits: A European company wanting its data under German law.
  • Does not suit: Anyone reading the card price and taking it for what they will pay.

Migadu

4.4Poor

Unlimited addresses and domains on one subscription, so your bill does not grow when your team does. That is the opposite of what fourteen services here do. The flaw is that the limit falls on daily messages, and the entry tier withholds features the page never names.

Unlimited addresses. Unlimited domains. Some features unavailable.

What their page says · www.migadu.com

And what it does not say: The page does not name the features withheld from the entry tier, and writes no renewal price and no refund window.

The price is $7.50 a month billed yearly for the whole account, not per mailbox. Five mailboxes cost what one costs, and so do fifty.

The limit is on messages in and out per day, and the page prints both figures for every tier. Anyone sending a newsletter or automated invoices counts their messages before choosing.

No language tags on the page at all and no switcher, with support pages in English alone. A small Swiss company selling to a technical audience.

The price is $15.00 a month for a team of five mailboxes billed yearly, rising a little month to month. With it comes your own domain, IMAP, a migration tool and a calendar.

The tier above the entry plan gives ten times its storage and is probably what a real team will buy. The page prints its price plainly.

No Arabic language tag and no switcher, with a help centre in English. An Australian company selling to an English-reading audience.

And what it does not say: No renewal price, no published refund window, and no monthly billing named on the business tier.

The price is $16.30 a month for a team of five mailboxes, with your own domain, reasonable storage, aliases and an admin console.

A shared mailbox is charged at the per-user rate, so anyone wanting an address for enquiries and another for sales pays for them as for employees.

No Arabic in the published language set or the support pages. How search inside encrypted mail behaves with Arabic text is a question we did not test.

Comparison table: 5 services

Use this table once you know what matters to you. Start with the column that fits your project: response from your audience's city, the first payment and renewal if budget is the constraint, or the reply language if you will lean on support. Narrow the list with the filters below. Every “Not yet measured” cell is a criterion left out of the score until we check it, not a zero. Reading one row: Proton Mail scores 4.5, it scores 7.7 on features, it answers from Riyadh in 0 ms, you pay $419.40 today and then —/mo, and it was checked on 24 September 2026.

Which email provider for your business?

No single provider suits every project. These are cases we hear about often, each with the criterion that decides it, the provider that leads on it among the ones we recommend, and what to watch for.

    Read the price before you buy

    “From $7.50 a month” is true and misleading at the same time. That price usually comes only with a prepayment of several years, and it rises at renewal. Before you compare monthly prices, compare two numbers: what you pay today, and what you pay in the first 36 months.

    Take the services that led a criterion this round and compare the first-payment column with the first-36-months column before you decide: a small first payment does not mean a small cost.

    Scroll the table sideways for the 36-month total and the monthly average.

    The table shows US dollars before VAT, as the providers list them. Add VAT for your country, convert at the rate on the day you pay, and remember that your card fees can add a little. In your currency: Proton Mail's first payment of $419.40 is about 1573 SAR before VAT, and about 1809 SAR with 15% VAT in Saudi Arabia, at the rate on 24 September 2026.

    Choose the prepayment length you are sure to stay for. If you might leave within a year, compare the first-12-months column, not the 36.

    Where the prepayment is longer than the period, the whole prepayment is shown because nothing shorter can be bought at that price. Prices in US dollars as shown on the providers' sites. For reference, $1 ≈ 3.75 SAR ≈ 3.67 AED ≈ 48.5 EGP at the rate on . Add VAT (15% in Saudi Arabia, 5% in the UAE, 14% in Egypt) where not included. mada and Fawry are accepted by: .

    What the small print means

    Plans pages use words that sound clear, but what they mean is in the terms. These are five we read in every review, what they usually mean, and what to do before you believe them. These definitions are a general guide from the terms we read, not measured figures. Every number on this page comes from the company’s own page.

    “Unlimited”: Unlimited storage and data transfer come with a file-count (inode) cap and a CPU cap, and an active store can hit the cap within the first year. Ask about the file-count cap before buying if you are building a shop.

    “24/7 support”: Means the chat is open, not that anyone answers in Arabic or within minutes. We read the hours, the channels and the languages a support page names. Reply time we have not measured: that needs a paid account, and it is not in the score today. Try it yourself: send a question in Arabic before you pay. What we found: 0 of 5 services state on their support page that they reply in Arabic.

    “Free domain”: First year only, then renewed at market price ($12 to $20). It may be held back if you cancel. Register the domain in your own name, and check its renewal price.

    “Money-back guarantee”: Usually excludes the domain and add-ons, and runs from the purchase date, not the activation date. Read what is excluded, and count the window from the purchase date.

    “Free migration”: Usually between similar services only. Moving from another email provider or a private mail server is paid. Check that your mailboxes are the kind they move for free. What we found: 0 of the 5 providers on the list advertise free migration.

    Before you pay

    Before you type in your card number, take ten minutes for these steps. Each one protects you from a mistake that recurs across these companies’ pages. Every review on this site lists the refund window, how to cancel and the renewal price for its provider.

    1. Confirm the refund window and whether it covers what you bought. Many providers exclude the domain and add-ons, so only part of the money comes back.
    2. Know how to cancel: from the panel or by phone only. Some providers cancel only by ticket or phone, which eats into the refund window.
    3. Put the renewal date in your calendar with the new price. The new price is charged automatically, often without a clear reminder.
    4. Confirm you can export a full backup yourself. That copy is what lets you leave if the service goes bad.
    5. Choose the mail storage region before paying; some services will not change it afterwards. Changing region after the account exists means moving the mailboxes all over again.
    6. Message support in Arabic before buying and time the reply. What happens with a pre-sales question tells you what will happen after the sale.

    What these companies’ own pages said

    We read the pages of 5 companies in one day. We bought no plan and wrote to no support desk. What follows is not a judgement of service quality; it is a count of what each company says about itself on its own page: how far the price rises, how long it demands up front, what it promises, and what it does when you ask for your money back.

    Three numbers summarise what we found, all computed from the same list you are about to read.

    • 0/5median renewal jumpwhat the offer price becomes at renewal, in the middle of the list
    • 0/5print the renewal on the pricing pageof the 5 companies we read
    • 0/5publish Arabic supportof the 5 companies we read

    The third number is the one that matters to an Arabic-speaking reader: nothing on this list promises Arabic on its own page. The companies that publish their support languages name English, Spanish and German, and the list ends there.

    The score is out of ten: four sub-scores multiplied by their weights. For each criterion below: what it means in a buyer’s terms, where every company stands on it, and the formula that produced the number.

    Price and billing transparency

    25%

    The renewal jump alone is not enough: a company demanding four years up front at a flat price can cost you more than one that raises its price after a single year. So this criterion adds four things — the jump, the term demanded, whether the renewal is written down at all, and how much leaves your card today.

    1. Migadu6.2
    2. mailbox.org5.8
    3. Tuta5.6
    4. Fastmail5.5
    5. Proton Mail4.2

    Migadu sits at the head here (6.2); Proton Mail sits at the foot here (4.2).

    The formula as we apply it: The price we compare: what five mailboxes cost a month on the entry paid plan, not the price of one, because a provider that charges for the account rather than the mailbox looks expensive in a per-user column and in fact costs little. Converted to one currency at a dated rate. Price level 35%, the monthly premium 15%, the term demanded 15%, a free tier 15%, and the renewal price printed on the page 20%.

    Arabic and right-to-left support

    20%

    This criterion asks what the English lists do not: is the editor interface in Arabic, can a site be built right to left, are there Arabic templates, and is support offered in Arabic. Each answer comes from the vendor’s own published language list and its own help pages, never from a tick mark in somebody else’s table.

    2. mailbox.org0.0
    3. Migadu0.0
    4. Proton Mail0.0
    5. Tuta0.0

    Fastmail sits at the head here (0.0); Tuta sits at the foot here (0.0).

    The formula as we apply it: Arabic: four places, every one of them read on the company’s own pages. The mail interface’s language, whether the company publishes right-to-left support, whether it has Arabic pages, and whether its support answers in Arabic. The score is what we found over what we actually read: a place we could not reach leaves both halves of the fraction, so no company is marked down for a page we failed to finish, and its card says how many places we read. This measures what the company publishes, not what its product can do.

    Published features

    35%

    The seven items are not worth the same to someone running a small site: a daily backup saves a site, an email address does not. So each feature is weighted by what it is worth, not counted.

    1. Proton Mail7.7
    2. Migadu6.7
    3. Fastmail5.7
    4. mailbox.org5.4
    5. Tuta5.4

    Proton Mail sits at the head here (7.7); Tuta sits at the foot here (5.4).

    The formula as we apply it: What the mailbox gives you: its capabilities 60% and its storage 40%. The capabilities are your own domain, IMAP, a migration tool, office applications, a calendar, an admin console, aliases and a retention policy, each counted against what we read rather than against a fixed list. Storage runs on a curve: two gigabytes scores nothing, fifteen about five, a hundred about nine, and nothing reaches ten, because there is always more storage to be had.

    Support availability

    20%

    We do not know how long they take to reply, because that needs a paid account. What we do know is what they publish: when you can reach them, on how many channels, and in what language.

    1. mailbox.org5.6
    2. Fastmail3.8
    3. Proton Mail3.8
    4. Migadu2.5
    5. Tuta2.5

    mailbox.org sits at the head here (5.6); Tuta sits at the foot here (2.5).

    The formula as we apply it: Support: contact channels 40%, published hours 35%, and the way back 25%. Hours are 10 around the clock, 5 for business hours, 0 when none is published. The way back takes whichever is longer, the refund window or the free trial, because what it measures is whether you can undo the purchase, not by which means.

    How to read a number out of ten

    Eight and above: the company writes down what you will pay and when, and gives you a way out. There is no nine on this list, and that is not modesty on our part — we did not find a page that earned one.

    Seven to eight: a mostly clear page with one flaw worth reading before you pay.

    Six to seven: the advertised price is far from the real one, or the term demanded is long, or something basic goes unmentioned.

    Under six: the page hides more than it says. The company still has a link here, because the decision is yours, but read the weaknesses first.

    Where two scores tie after rounding, the higher unrounded sum ranks first. No position is moved by hand.

    What we did not measure, and why you should know

    We bought no plan from anyone on this list, ran no site on one, and sent no question to a support desk. That means speed, uptime and real reply times enter no score on this page.

    That is a choice, not a hidden gap: we published what can be verified today instead of waiting for a purchase budget, and we state its limits. When we buy and measure, those criteria enter the arithmetic, the scores move, and the change appears in the changelog with its date.

    Until then, what you are reading answers one question precisely: what does this company say about itself, and does it say it clearly?

    Latest changes in this category

    • The scoring model changed: five criteria that assumed we had bought the plan became 4 that are read from the companies’ own pages — price 25%, Arabic 20%, features 35%, support 20%. Speed and uptime left the score entirely until they can be measured on a bought plan, and the page says so everywhere.
    • Each measurement's points are now rounded to two decimals before they are weighted; no score changed.

    Frequently asked

    Should I buy the domain from the provider?

    Not necessarily. The free first-year domain is convenient, then it renews at market price, and some terms hold it back or deduct its fee from any refund. Registering it with an independent registrar keeps the domain separate from the business email and makes moving later easier.

    Can I move later, and what does it cost?

    0 of the 5 companies on this list publish free migration on their plan page: . It is usually the admin console to the admin console only; moving from a site builder or a dedicated server is a paid service, and some terms cap how many sites move free.

    Is a free plan enough for my business email?

    For personal mail, perhaps. For a business writing to customers, no; free services usually come with ads and no backups. We did not measure any of them in this round.
