About Senin Mail
Email should feel calm, not chaotic
Most of us have more than one inbox, and a different app or tab for each. We're building one place where all of them live, without moving your mail anywhere.
- Built around your privacy
- Your mail stays at your provider
- Honest about what is ready
Our mission
One calm place for every account
Work, side projects and home each get their own address, and each address gets its own tab, app and set of habits. The result is missed messages and wasted minutes. Senin Mail puts them all in one clear, consistent, fast workspace.
- Treat every account equally, with the same folders, search and composer
- Never take your mail hostage: it stays with your provider
- Make the everyday actions instant and the dangerous ones deliberate
Every account in one view
Your data, your control
Fewer tabs, fewer clicks
Safe by default
What we believe
Principles we build by
They're short, and they decide a lot of trade-offs.
Privacy is the default
We collect what we need to show your mail and nothing more. No ads. No selling data.
Your mail stays yours
We're a client. Everything you do happens in your real mailbox, so you can always leave.
Fast is a feature
Actions respond instantly and sync catches up. If something fails, it rolls back and tells you why.
No surprises
Destructive actions ask first. Limits and behaviours are written down, not discovered.
Tested, not hoped
Security-sensitive behaviour, like one user never seeing another's mail, is covered by automated tests.
Open about status
We say what works, what doesn't yet, and what's next, on the changelog and roadmap.
How it works
A client, not a cloud copy
The idea is simple, and it matters for your privacy.
Your provider keeps your mail
Gmail, Outlook and your IMAP server remain the source of truth.
We connect with your permission
OAuth tokens or an app password you provide, stored encrypted.
We keep a small cache
Enough to show your inbox instantly: sender, subject, preview, date and flags.
Changes go to the provider
Read, star, move, send: it all happens in your mailbox, so other apps see it too.
Who it's for
Anyone with more than one inbox
People
Personal and old addresses that still matter.
Read everything in one place, with no forwarding rules or migrations.
Professionals
Client, company and project mail.
File threads into real folders and always reply from the right account.
Small teams
Support aliases and shared addresses.
Open any message from a link, and keep each address's folders and state.
Under the hood
Built with solid, familiar tools
Modern web technology, chosen for reliability.
Next.js & React
A fast, responsive interface that works in your browser.
PostgreSQL
A reliable database for accounts, folders and the message cache.
Provider APIs
Gmail API, Microsoft Graph and standard IMAP/SMTP.
Encryption
AES-256-GCM for credentials, with key rotation built in.
Where we're going
What's next
A few of the things on our list. The changelog has the full picture.
Instant notifications
Push from Gmail and Outlook so new mail arrives the second it's sent.
Smarter search
Search inside message bodies and attachments, and save common searches.
Team features
Shared inboxes and assignment for small teams.
