Write better work emails in a language that isn’t your first

Why work email is harder than it looks

Most of us learned email English from templates: “I am writing to inform you”, “Please do not hesitate to contact me”, “Thank you in advance for your cooperation”. None of them are wrong. They just make a short note to a colleague sound like a letter from the tax office, and stacked together they read as translated.

The opposite problem is worse. Translate a direct request from your own language and “Send me the file today” can land as an order. Somewhere between the two is the email a native speaker would write, and finding it in a second language takes time you don’t have between meetings. So you reread a five-line email to your manager four times and still aren’t sure about it.

AI Grammatic fixes the grammar, then rewrites the parts that sound stiff or translated. These are the kinds of sentences it changes.

Casual or formal, one key apart

Who you’re writing to matters as much as what you say. Every language in AI Grammatic has two tones. ⌘⌥E gives you casual, for your team and the people you email every day. Add ⇧ for formal, for a new client, a vendor or your manager’s manager.

Not sure which one an email needs? Our guide to casual vs formal English has the rules of thumb.

Reply fast, in your own language first

When an email needs an answer in the next five minutes, write the reply the way you’d say it in your own language. Select it and press your English shortcut. It comes back as natural English, in the tone you picked, not as a word-for-word translation.

It works in the other direction too. Give French or German its own shortcut, write your reply in English, and send the office in Lyon or Munich something that sounds local. There are more than 30 languages to choose from, each with its own shortcut and both tones.

It edits your email. It doesn’t write it.

AI Grammatic isn’t an email generator. It keeps your meaning, names, numbers, links and line breaks, and the result is about as long as what you wrote. It won’t add a greeting or a sign-off you didn’t write, it never uses em dashes, and it stays away from stock phrases like “I hope this email finds you well”. The email still sounds like you, just without the mistakes and the translated feel.

Works in the mail app you already use

There’s no plugin to install. AI Grammatic uses a system-wide shortcut, so it works anywhere you can select text: Apple Mail, Outlook, Gmail in Safari or Chrome, and the Slack or Teams message you write right after. It runs from the menu bar on macOS 14 or later, and ⌘Z brings back your original if you change your mind.

Two settings worth a look for email. Set the rewrite style to professional if most of your mail goes outside the company. And if your clients are in the UK, pick English (UK) as the target language or add a custom instruction such as “Use British spelling”. Custom instructions take up to 500 characters and are included on every plan.
