What the email is aboutTone

Example email

From: you
To: [recipient]
Subject: Q3 report: can we move the deadline to Wednesday?

Hi Dana, I'd like to ask for a few more days on the Q3 report. The finance numbers reached me three days later than planned, and I don't want to send you something built on half-checked figures. Could we move the deadline from this Friday to next Wednesday? I can still send you a partial draft on Friday so you can see the structure and flag anything early. If Wednesday causes a problem on your side, tell me and I'll find another way. Thanks, [your name]

Asking for a deadline extension

The numbers you needed came in three days late. You have to ask your manager for more time without it sounding like an excuse.

You typed

Email to my manager Dana asking to move the Q3 report deadline from Friday to next Wednesday. The finance numbers arrived three days late. Offer to send a partial draft Friday.

You asked: Professional tone. Offer the partial draft.

To: [recipient]
Subject: Q3 report: can we move the deadline to Wednesday?

Introducing yourself to a new client

You've just taken over an account. The first email decides whether the client sees a handover or a downgrade.

You typed

First email to a new client, Rosa at Tidewater Dental. I'm their account manager from now on. Want to introduce myself and set up a 20-minute kickoff call next week.

You asked: Friendly tone. Ask for a 20-minute call.

To: [recipient]
Subject: Your new contact at [company]

Hi Rosa, I'm [your name], and from this week I'll be your account manager for Tidewater Dental. Anything you'd have sent to the team before, you can now send straight to me. I'd like to hear how things have gone so far and what you want from the next few months. Do you have 20 minutes for a call next week? Tuesday or Thursday afternoon both work for me, or pick a time that suits you better. Looking forward to working with you, [your name]

Announcing a price change

Prices are going up. Customers need the number, the date and their options, in that order, with nothing dressed up.

You typed

Tell existing customers our monthly plan goes from $29 to $34 on March 1. Annual plans stay the same until renewal. They can lock the old price by switching to annual before then.

You asked: Formal tone. Lead with the new price.

To: [recipient]
Subject: A change to monthly pricing from March 1

Dear [first name], From March 1, the monthly plan will be $34 per month, up from $29. If you are on an annual plan, nothing changes until your renewal date. If you would like to keep the current price, you can switch to annual billing any time before March 1 and it will be locked in for the full year. You do not need to do anything if you are happy to continue on the monthly plan. If you have questions about your account, reply to this email and we will help. Regards, [your name]

What an AI email writer does

An AI email writer turns a short description into a complete email: a subject line, a greeting, the body, and a sign-off. You say who it's for and what you need, and it handles the part most people find slow, which is getting from a blank compose box to a first draft.

You will see the same thing called an AI email generator. The names are interchangeable. What matters is whether the draft is specific. A good email writer uses the facts you gave it and leaves a bracketed placeholder where a fact is missing, instead of inventing a date or a number to fill the gap.

What to put in the description

The draft can only be as specific as the description. Four things make the difference:

Who it's for and how you know them. "My manager", "a client I've never met" and "my landlord" produce three different emails.
The one thing you need. A decision, a meeting, a payment, an introduction. If you can't name it, the email won't either.
The facts that must be in it. Dates, amounts, order numbers, names. Leave them out and you get placeholders.
Anything you are offering in return. A partial draft, a later date, a discount. It changes how the ask lands.

Two sentences covering those four points beats a paragraph of background.

Business email writer or quick note: picking the tone

Most people arrive here needing a business email writer: something that sounds competent to a client, a manager or a supplier. That is what the professional tone is for, and it is the default.

The other three cover the edges. Friendly is for people you already work with. Formal is the professional email generator setting for banks, landlords, universities and anyone you'd address as "Dear". Concise strips the email to the ask and the deadline, for readers who decide in the first two lines.

If a draft feels stiff, it's usually because formal was chosen for someone who would have been fine with professional.

AI email writer vs a ChatGPT email writer

You can use ChatGPT as an email writer, and plenty of people do. The trade-off is the prompt. In a chatbot you have to say that you want an email, how long, in what tone, with a subject line, without invented details. Here those rules are built in, so the box only asks for what the email is about.

If you searched for an AI email generator free of the prompt-writing step, that is the difference. The other one is what happens after the draft: "Continue in Zentor" carries it into a workspace that can send it from your Gmail and write the reply when the answer comes back.

When one email is not the problem

An email writer helps with the email in front of you. It does nothing about the forty behind it. If the real cost is the time spent answering, chasing and remembering, Zentor's AI email assistant does that inside Gmail: it reads the thread, drafts what you'd probably say, and leaves it for you to approve.

Questions

Is the AI email writer free?

Yes, the AI email writer is free. Generate opens Zentor, where you sign in or start a free trial and the email is drafted for you.

Do I need to sign up?

Yes. Generate hands off to Zentor, where you sign in or start a free trial and the email is drafted for you.

What kinds of email can it write?

Requests, introductions, announcements, apologies, thank-yous, complaints, scheduling notes. If you can describe who it's for and what you need, it can draft it. For replies to an email you received, the email reply generator is the better fit.

Will it make up facts?

It is instructed not to. Where a detail is missing, such as a name, a date or a figure, the draft uses a bracketed placeholder like [date] so you can see what to fill in.

How is this different from ChatGPT?

There is no prompt to write. The length, structure, subject line and the rule against invented details are already set, so you only describe the email.

Can I use it for work email?

Yes. Professional is the default tone and most of the examples are work situations. Read the draft before sending, as you would with anything written for you.

How long are the emails?

Under about 200 words unless the description needs more. Pick the concise tone for the shortest version.

Does it write in languages other than English?

Describe the email in the language you want and the draft will usually follow. The examples and tone labels are English.

Is what I type private?

Keep what you paste generic where you can: names and rough details are fine, skip confidential terms and personal data. The privacy policy covers how Zentor handles data.
