You spend hours writing emails every week. And still, your drafts can feel generic or rushed.

AI email writers fix that.

In this article, you’ll see the best AI email tools built for this job.

1) Noota

What it is.
Noota is your AI email writer built on top of your meetings and calls. It drafts follow-up emails from transcripts and action items, so you send clear next steps without typing. It plugs into Meet, Zoom, Teams, Webex, and your browser.

Why it matters for you.
You already meet, call, and take notes. Noota turns that context into ready-to-send emails in minutes. You keep momentum with candidates, clients, or teammates.

How it works.
Noota records or joins your meeting, transcribes in real time, and identifies decisions and tasks. When the call ends, it generates a clean email draft that mirrors what you agreed. You review, tweak tone, and hit send.

Best use cases.
You run interviews and need fast, consistent follow-ups. You host client check-ins and want summaries plus next steps sent right away. You coordinate internally and want less copy-paste between tools.

3) MailMaestro (formerly Flowrite)

What it is.
MailMaestro is a dedicated AI email writer that lives in Outlook and Gmail. It drafts, rewrites, and summarizes emails directly in your inbox. It also compresses long threads so you reply fast with context.

Why it matters for you.
You spend too much time on first drafts and thread triage. MailMaestro turns bullet points into polished emails and trims threads to the key facts. You ship replies in minutes, not half an hour.

What changed with Flowrite.
