Example Output
Subject: Requesting a one-week extension on the Q2 deliverable
Hi Sarah,
I hope your week is going well. I'm writing to ask for a one-week extension on the Q2 analytics deliverable, moving the deadline from April 18 to April 25.
Two things came up that made the original timeline tight: the data warehouse migration ran longer than expected, and the new attribution model needs an extra review pass before I'd be comfortable sharing the results with the leadership team.
I'd rather deliver something we can trust than hit the original date with numbers that need asterisks. If the extension works for you, I'll have the full report in your inbox by end of day April 25. If the original timeline is critical, let me know and I'll prioritize getting you a partial draft by the 18th.
Thanks for understanding.
Best,
Alex
What is an AI email writer?
An AI email writer is a tool that turns a few structured inputs — who you are writing to, what you need to say, what tone you want — into a complete, ready-to-send email. It handles the parts of email writing that eat time without adding value: finding the right opening, structuring the body logically, striking the right tone, and ending with an appropriate sign-off. You still decide what to say; the AI handles how to say it.
This matters because email writing is a tax on knowledge work. A typical professional spends 28% of their day on email, and a significant chunk of that is staring at a blank compose window trying to figure out how to phrase something. An AI email writer collapses that staring time from minutes to seconds.
How to write an email with this tool
Fill in the form above with the details the AI needs. The more specific you are, the better the email:
- Recipient — who you are writing to (your manager, a client named Sarah, the whole engineering team). Specificity shapes the voice.
- Email subject — the topic in a few words. This becomes the basis of the subject line.
- Key points to cover — the things that must be in the email. List them as concisely as possible; the AI will expand.
- Tone — professional and polite, friendly and casual, formal and authoritative, or urgent and direct. Pick the one that matches the situation.
- Additional context (optional) — anything the AI should know that is not a key point: prior conversations, deadlines, relationships.
Types of emails you can write with this tool
The AI email writer is a generalist — it handles most common email types well:
- Work emails: status updates, deadline extension requests, meeting requests, project handoffs, escalations.
- Client communication: follow-ups, proposal responses, scheduling, check-ins, thank-you notes.
- Internal announcements: team updates, policy changes, role transitions, launch notes.
- Personal-but-formal: thank-you notes to vendors, replies to invitations, scheduling with professionals.
- Difficult conversations: declining a request, delivering bad news, pushing back on a deadline, asking for a raise.
- Follow-ups: post-meeting recaps, reminders, nudges on unanswered threads.
Tips for better AI-generated emails
The single biggest lever on email quality is the specificity of your inputs. A few rules that consistently lift the output:
- Use real names and roles in the recipient field, not generic titles. 'Sarah, the product manager' beats 'a manager.'
- Put actual facts in the key points field — dates, numbers, names. The AI cannot invent specifics it does not have.
- Match the tone to the reader, not to yourself. A client you barely know gets 'professional & polite' even if you are casual with coworkers.
- Read the output once before sending. The AI is fast but not infallible; a thirty-second review catches the occasional off-brand line.
- If the first version is not right, regenerate with a different tone — you will get a genuinely different email, not just a reworded one.
Frequently Asked Questions
Is this AI email writer really free?
Yes — completely free with no sign-up, no credit card, and no limits. Write as many emails as you need, for any purpose, as often as you want.
Do I need to create an account?
No account, no email, no password. Fill in the form, pick a tone, and generate. We do not store your inputs or outputs.
Will the email sound natural, or like AI wrote it?
It depends on what you put in. If you give the AI specific key points and context, the output reads like a human wrote it. If you give it vague instructions, the output will be generic. The tool is only as good as the details you provide — the form fields are designed to pull those details out of you.
Can I use this for cold sales emails or outreach?
You can, but for cold outreach specifically we recommend the AI Cold Email Writer (also free) — it is tuned for shorter, hook-driven messages with a soft CTA, which is what converts for cold outreach. This general email writer is better for replies, follow-ups, requests, announcements, and internal work emails.
How is this different from Grammarly's or QuillBot's email writer?
Grammarly and QuillBot both require sign-up and nudge you toward paid subscriptions. aiwriter.ai's email writer is free with no sign-up, no usage limits, and no content restrictions — so you can draft difficult emails (confrontational, sensitive, creative) without the tool refusing or softening the content.
Can I write emails in languages other than English?
Yes. Write your recipient, subject, and key points in the target language and the AI will respond in kind. It handles most major European and Asian languages well — test a sample email in your language to see the quality before relying on it.
Does the output include a subject line?
Yes. The tool generates a subject line, greeting, email body, and sign-off as a complete email ready to copy into your mail client.
