ReciteMail
Best for private drafting in your own voice
€29.99 a month or €299 a year, one person, unlimited under fair use
ReciteMail drafts the reply you are about to send, in a voice learned from your own sent mail. It signs in to no mailbox at all. You bring one email in by pasting it or snipping it off the screen, read the draft it writes, then send it yourself from whatever inbox you already use. Your imported mail stays encrypted on your own PC.
Where it wins. Nothing connects to your email. No tool holds standing access to years of correspondence. It keeps customers and suppliers apart with separate tones, it reads and replies in 60 or more languages and the price is flat no matter how many emails you answer.
The catch. It is Windows 10 and 11 only, with no Mac or mobile app. It does not sort your inbox or draft automatically in the background. You hand it each email, which is the trade for it seeing nothing else.
Fyxer AI
Best for hands-off drafting and sorting together
$30 a month Starter or $22.50 on annual billing; $50 a month Professional. Seven day trial, no free tier
Fyxer signs in to Gmail or Outlook, categorises your incoming mail and writes ready-to-send drafts in a learned style while you are away. It also takes meeting notes. It is the closest thing here to a full assistant that works your inbox for you.
Where it wins. The drafting and the sorting happen automatically. You open your inbox to replies already written, which is a real time saver if you are comfortable with a tool reading everything.
The catch. It needs full mailbox access to do any of that. It is priced per person, with higher tiers for automation. If handing an app your whole inbox is the sticking point, this is the opposite approach to ReciteMail. Full comparison →
Superhuman
Best for speed and keyboard power users
$30 a month Starter or $25 on annual billing; $40 a month Business or $33 annual
Superhuman is a premium email client, now part of Grammarly, built around speed, keyboard shortcuts and a polished interface. Its AI writes and auto-drafts replies, with the strongest drafting features on the Business tier.
Where it wins. If you live in email all day and want the fastest possible client with AI built in, few things feel as quick. It runs on Mac, Windows, iOS and Android, which ReciteMail does not.
The catch. It replaces your email app and connects to Gmail or Outlook to do so. The price is high for a single person who only wants help writing. Full comparison →
Shortwave
Best AI-native email client for Gmail
Free tier available; Pro $18 a month or $14 on annual billing; Business tiers above that
Shortwave is an email app built around AI from the ground up, with search, summaries and drafting woven through it. It is Gmail only and does not support Outlook at all.
Where it wins. On Gmail it is one of the most capable AI clients going. There is a usable free tier. It runs on desktop, web and mobile.
The catch. You are switching email apps and connecting your Google account. If you are on Outlook it is not for you. Full comparison →
Microsoft 365 Copilot
Best if you already pay for Microsoft 365
Add-on from $21 per user a month for businesses under 300 seats, $30 per user at enterprise, on top of a base Microsoft 365 licence
Copilot sits inside Outlook and the rest of Office, drafting and summarising with the context of your Microsoft account. If your work already runs on Microsoft 365, it is right there in the app you use.
Where it wins. Nothing new to install and nothing extra to learn, with drafting across Word, Excel and Outlook rather than email alone. It runs everywhere Outlook does.
The catch. It is an add-on cost on top of your existing licence. It drafts in a generic assistant voice rather than one learned from how you write. Full comparison →
Gemini in Gmail
Best if you live in Google Workspace
Bundled into Google Workspace business plans and Google One AI plans; not sold separately since March 2025
Gemini drafts and summarises inside the Gmail tab, with the context of your Google account. For Workspace subscribers it is already there at no extra charge on most current plans.
Where it wins. Zero setup if you are on Workspace. It works on every device Gmail does. Help with writing is one click away in the app you already have open.
The catch. It stops at the Gmail tab, it reads your whole mailbox by design and the voice is Google's rather than yours. Full comparison →
SaneBox
Best for triaging a flooded inbox
From $7 a month Snack up to $36 a month Dinner; annual billing saves roughly a fifth
SaneBox does not write anything. It studies what lands in your inbox and files the noise into folders so what is left is the mail that matters. It works with any provider over IMAP, which means it fits Gmail, Outlook and the rest.
Where it wins. If your problem is volume rather than writing, this is the cleanest fix. It never changes your email app. Many people run it alongside a drafting tool.
The catch. It is solving a different half of the problem. It will not draft a single reply for you. Full comparison →
MailMaestro
Best budget drafting add-in for Outlook and Gmail
Free tier available; paid from $12 a month, with a 14 day trial
MailMaestro is an add-in that lives inside Outlook and Gmail and drafts replies in your style from a short brief. It is the closest rival here to what ReciteMail does, with the difference that it works inside your mailbox rather than beside it.
Where it wins. It is inexpensive, there is a free tier to try and the drafting sits right where you already read your mail.
The catch. It is an add-in, which runs inside your mailbox and needs that access. ReciteMail keeps the drafting outside the inbox entirely. Full comparison →
