Your inbox, on hyperspeed.

Mailon reads every message, drafts a thoughtful reply, and sends it after a delay you can cancel.

Reclaim hours a day — without ever losing control of what goes out.

You stay in control

AI drafts. You have the final say.

Handing your inbox to an AI shouldn't mean losing control. Every reply waits in a cancellable window before it goes out — and anything the AI is unsure about is escalated to you instead of sent.

How it works

Live in three steps.

From sign-in to your first auto-drafted reply in minutes — no integrations team required.

01

Connect your mailbox

Sign in with Google or Microsoft 365. Mailon provisions an inbox and starts watching for mail — no forwarding rules to wrangle.

02

Teach it your voice

Write a short prompt and upload your reference docs — policies, price lists, past emails, PDFs. Replies are grounded in your actual sources.

03

Let it reply

Mailon drafts in your tone, holds each reply in a cancellable window, and escalates anything it is unsure about to you.

Features

Everything an inbox needs to run itself.

Knowledge base

Upload PDFs, Office docs, emails and more. Mailon retrieves the right passage and cites it — replies are grounded in your truth, not made up.

Human-in-the-loop

Unsure replies are escalated to a review queue. You approve, edit, or rewrite — the AI never sends something it can't stand behind.

Your voice, per mailbox

Each mailbox has its own prompt and tone. Support sounds like support; sales sounds like sales.

Model choice

Runs on Claude or GPT — pick per mailbox, switch any time. No lock-in to a single provider.

Spam & triage built in

Junk is filtered automatically; real mail is classified and summarised before a reply is ever drafted.

Works with your email

Google Workspace and Microsoft 365 sign-in out of the box. Bring the inbox you already use.

Built for

Support teams, founders, and freelancers who get more email than they can answer — and refuse to let replies slip.

Questions

The things everyone asks first.

Will it send something embarrassing on my behalf?

Every reply waits in a cancellable window before sending (30 minutes by default), and anything the AI is uncertain about is escalated to you instead of sent. Nothing leaves without a chance for you to stop it.

Does it actually sound like me?

You write a per-mailbox prompt that sets the tone, and Mailon grounds replies in the reference documents you upload. It paraphrases your sources rather than inventing answers.

What email providers does it work with?

Google Workspace and Microsoft 365 today, via secure OAuth sign-in. Email/password accounts are supported too.

Is my email data safe?

Your documents and messages are scoped to your organization and never shared across tenants. You control exactly which documents each mailbox can draw on.

What does it cost?

Your first replies are free so you can see it work before paying. Detailed pricing is on the way — get started now and we will keep you posted.
