The problem
Your inbox is not short of features. It is short of your time.
Mail arrives faster than anyone reads it. The important message sits three screens down, under a receipt, a newsletter and a calendar invite. By the time you find it you have read forty things you did not need to.
What it is
An assistant that has already read your mail
Cusentra Mail connects to the Gmail you already use. It syncs in the background, sorts by rules you describe in your own words, and has a summary and a draft reply waiting when you open a message. Nothing it writes is sent until you send it.
Rules, not guesswork
Categories and detections run without a model, so they are instant, free and the same every time.
Your writing, not a robot's
Drafts are learned from your own sent mail. Your name and sign-off come from your profile.
You send, not the app
Every draft waits for you. Cusentra Mail never sends an email until you press Send.
Is this you?
Built for people whose inbox is the job
You open the same mailbox forty times a day and still miss things.
You write the same three replies over and over, in slightly different words.
You want the sorting to follow your rules, not a provider's idea of a tab.
You are not willing to let software send mail as you.
Features
Nine things, all of them about the same goal
Less time in your inbox, without giving up control of it.
Replies in your own writing
It learns your style from your sent mail, then drafts in it. Your name and sign-off come from your profile, never invented.
Rules you write in English
"Anything from my accountant is Finance." Categories and detections are yours, and they run without a model — instant and free.
Chat with your mailbox
Ask what's on your plate, what someone last said, or what you promised. It answers from your mail, and most answers cost nothing.
Follow-ups that only you set
Mark what you're waiting on and what you promised. Nothing is guessed at you — if you didn't set it, it isn't chasing you.
Automations with a review queue
Have drafts prepared while you're away, posted to Slack, or saved as a note. Replies wait in a queue until you tick and send.
A daily report
What arrived, what you did, what's still open — built for one local day and saved or emailed to you each evening.
Your tools, connected
Notion, Google Docs, OneNote, Slack, Teams, Discord and Google Calendar — connected only where you switch them on.
Search that reads bodies
Filters like from: and has:attachment, plus full message text searched through your own mailbox.
How it works
Three steps, about two minutes
-
1
Connect Gmail
Sign up, then paste one Google app password. It's checked live before your account is created, so you know straight away that it works.
-
2
It reads your mailbox
Your mail syncs in the background and keeps itself current. The first pass takes a few minutes; after that, new mail appears on its own.
-
3
You stay in charge
Summaries and drafts are offered, never acted on. No email is sent without your approval — no automatic sends, ever.
Privacy
Built to be trusted with your mail
Encrypted at rest
Subjects, bodies and the text of the search index are encrypted with a key of your own, wrapped by a master key that never sits in the database.
AI only where you allow it
Every AI feature reads your consent first. Turn it off and the app keeps working — the rules, search and mailbox don't need a model.
Yours to take back
Download a copy of your data, or erase your account and its mail for good. Retention is a setting, not a promise.
Nothing sent behind your back
Drafts wait for you. Automations can prepare and post to your own tools, but they never send mail on your behalf.

FAQ
Questions people ask first
Does it work with any mailbox?
No — Gmail only, for now. The sync is built on Gmail's own IMAP extensions, so another provider would connect and then sync nothing. If you are not on Gmail, tell us on the sign-up page and we will let you know when your provider is supported.
Why a Google app password and not "Sign in with Google"?
An app password is a mailbox credential you create and can revoke at any time from your Google account, without touching anything else you use Google for. It is checked live before your account is created, so a wrong one cannot get you halfway through sign-up.
Will it ever send mail for me?
No. Drafts and automations stop at a review queue. You tick what you want and press Send yourself — no email is sent without your approval. It is the promise the whole design is built around.
Can I use it without the AI?
Yes. Every AI feature reads your consent first, and turning it off leaves a working mail client: the categories, detections, search, labels and the mailbox itself never call a model.
What happens to my mail?
Subjects, bodies and the text of the search index are encrypted at rest with a key of your own, on servers in the EU. You can download a copy of your data, and erasing your account deletes its mail for good. How long mail bodies are kept is a setting you control.
What if I use up my allowance?
That feature pauses until the weekly reset, and the rest of the app carries on. You are never charged beyond your plan, and reading your mail is never metered at all.
Ready to see your inbox differently?
Connect the Gmail you already use. You can erase everything on your way out.
