Make it shorter, more formal, or add a CTA — no need to rewrite the whole prompt.
Frequently asked questions about AI email writing
Is this AI Email Writer really free?
Yes, 100% free. No account, no credit card, no hidden limits. You can generate unlimited emails for personal or professional use. We offer a paid inbox warmup tool separately if you want to ensure your cold emails land in the inbox — but the AI writer itself is completely free.
How does the AI email writer work?
You describe what you want (who you're emailing, what you want to say, the tone) and our AI generates a complete email — subject line and body — in about 5 seconds. You can then refine the output with one-click actions like 'shorten' or 'make more formal'.
What types of emails can I write with this tool?
Pretty much any kind. Professional emails to your boss or colleagues, personal emails to professors, follow-ups with clients, meeting requests, resignation letters, thank you notes, cold outreach, apology emails, and more. We have 8 quick-start templates, but you can also write any custom prompt.
Is my email data private? Do you store what I write?
Your privacy matters. We don't store the content of the emails you generate, and we never share your inputs with third parties. Generated drafts are saved locally in your browser only so you can return to them — we don't keep copies on our servers.
Can this AI Email Writer reply to emails I receive?
Yes — that's one of our unique features. Switch to 'Reply to Email' mode, paste the email you received, tell the AI how you want to respond, and it generates a context-aware reply that actually addresses what the sender wrote.
What is the spam word detector and why does it matter?
Email providers like Gmail and Outlook filter emails containing 'spam trigger' words (like 'free', 'guarantee', '100%', 'urgent'). These words can send your message straight to the spam folder. Our tool automatically scans every generated email for these words and offers one-click AI rewriting to remove them.
What is Spintax and when should I use it?
Spintax is a syntax like {Hi|Hello|Hey} that lets you generate multiple variations of the same email. It's useful for cold outreach at scale, where sending identical emails to many recipients can trigger spam filters. Toggle on the Spintax option and the AI will include variation brackets in your email.
Can I customize the tone of the email?
Yes. You can choose from 6 tones: Professional, Friendly, Persuasive, Urgent, Formal, and Casual. You can also set the length (Short, Medium, Long). After generation, one-click refine buttons let you make it shorter, more formal, or add a call-to-action without rewriting your prompt.
Does this AI Email Writer work on mobile?
Absolutely. The tool is fully responsive and works on any device — phone, tablet, desktop. You can generate, copy, and send emails from your phone browser. No app download needed.
Will my cold emails land in the inbox or spam folder?
Great email copy is only half the battle — the other half is deliverability. If your domain isn't authenticated (SPF, DKIM, DMARC) or your inbox isn't 'warmed up', even the best email will hit spam. Our tool includes a deliverability checklist and we offer a 7-day free inbox warmup to make sure your emails actually reach their destination.
