— A SHORT MANIFESTO
Your inbox is not your job.
Sometime around 2008, email stopped being a tool and became a posture. A way of looking busy. A permanent half-open tab. Most of us now spend the best hour of our day refreshing it.
Coast is an argument in software form. It opens your inbox three times a day — morning, midday, and evening — and then firmly closes it. No unread count in your tray. No mobile notification at 11pm. No colored priority dots begging for your next dopamine hit.
What you get back is the thing email was supposed to leave you with in the first place: the rest of your attention, returned to the rest of your life.

THE PARTS
Four small ideas, held together by one big one.
01 / RHYTHM
Three visits a day
Coast opens your inbox at the times you pick — say 9am, 1pm, and 6pm — then locks it until the next one. In between, nothing. The world goes on without your reply and somehow survives.
02 / TRIAGE
Everything is a yes or a later
Every message has two keys: Reply now, or Snooze to the next visit. No folders, no stars, no coloured flags. You'll clear the inbox every single session.
03 / PRIVACY
Your mail, your machine
Coast runs on-device for Fastmail and IMAP, and talks to Gmail through Google's official API. Nothing you write passes through our servers. Nothing is stored.
04 / WRITING
A calmer composer
The composer is a plain white page with a word count. No AI rewrite button. No smart reply. Just you, a sentence, and the person on the other end.
A QUIET ROOM
Designed to be closed.
Most inbox apps reward you for staying. Coast rewards you for leaving. The interface thins out as you reply — lighter, quieter, smaller — until you hit Inbox Zero and the whole window dissolves into a single line of text: 'See you at 1pm.'
→
Session summary when you finish — how many replies, how much time, when the next visit is.
→
Focus mode hides sender names and subject lines — you read messages in the order they arrived, like real mail.
“
Coast is the first email app that ever made me feel less anxious, not more. I check it three times a day now and nothing has fallen apart. In fact, a lot has quietly fallen into place.
