Why Mailient
Email was supposed to be a tool. For most founders, it became the job.
Every founder has lost opportunities to an email they saw too late. You have too — you just can't name which one.
PAIN POINT 01
The email that sat in your inbox for three days while you meant to reply.
PAIN POINT 02
The client who went cold because you got buried in other threads.
PAIN POINT 03
The meeting that never got booked because the scheduling back-and-forth took a week.
PAIN POINT 04
The Sunday night dread of opening Gmail and seeing 200 unread messages staring back.
13 hours a week, gone to your inbox.
A part-time job you never hired for.
Gmail sorts what you read. Superhuman speeds it up. Claude connectors help when you ask. None of them run your inbox overnight — so the email you never opened still costs you the deal.
So Mailient isn't a faster inbox or another chat connector. It's a hire — completely open-source, and 100% free.
What it does
Three things, running without you.
Watch each one on a real inbox — no mockups.
The few emails that need a decision. The rest is handled.
See what mornings look likeHow it works
Three steps. Then it's handled.
Connect once, and stop thinking about your inbox.
STEP 1
Connect Gmail.
Two minutes, secure Google sign-in. Your email stays in Gmail — nothing moves, nothing to configure.
STEP 2
It learns how you write.
From your last 90 days of sent mail: your greetings, your rhythm, your sign-offs. Drafts start sounding like you, not like AI.
STEP 3
Mornings arrive organized.
Overnight it reads everything, drafts the replies, books the meetings, chases the silence — and leaves you one briefing. Nothing sends without your approval.
Connect Gmail
Two minutes. One sign-in. Done.
Your mail never leaves Gmail — nothing to migrate, nothing to configure.
Meet Arcus
Meet your new employee.
We named it Arcus. You'll just say: handled.
Tell it “clear my inbox and prep tomorrow.”
- Triages the flood
- Drafts replies in your voice
- Books the calls

Then shows you the few things that still need you.

Maily Core Hub
What mornings become
You open Mailient and there are only two emails left to think about. The other two hundred are read, sorted, answered, or archived — each with a note explaining what happened to it.
Why it's different
It learns who you are — your VIPs, your voice, what's strategic versus routine — and gets sharper every run. You're not operating software. You hired someone.
Your emails are encrypted in your browser before they leave it. Personal data is stripped before any AI sees it.

The short version: Mailient removes email from your to-do list entirely.
