Live UI preview · The sidebar accent, background pattern and density are all customisable.

Works with every mailbox you already have.

Add Gmail, Outlook, iCloud, Yahoo, Proton Bridge, Zoho, Fastmail, GMX, Yandex or AOL in two clicks. Or plug in any custom IMAP/SMTP host. Everything lands in the same unified inbox.

Gmail
Outlook
iCloud
Yahoo
Proton
Z Zoho
FM Fastmail
GMX GMX
Y Yandex
AOL AOL

Or any standards-compliant IMAP/SMTP server. Credentials are encrypted at rest with AES before they touch the database.

More than email. A full communications hub.

One account, one sidebar, one notification stream. Mail from every provider you already use, plus chat, calls, calendar, notes and contacts — all talking to the same address book.

Unified inbox

Add Gmail, Outlook, iCloud, Yahoo, Proton, Fastmail — any IMAP/SMTP mailbox — next to your @tacitusmail.com address. One combined view across every account, conversation threading, filters and attachment scanning with ClamAV.

End-to-end chat

Real 1:1 messaging between Tacitus users, encrypted with the Olm double-ratchet. Our server only sees ciphertext — the plaintext is decrypted on your device. Keeps working on iOS with push notifications and an offline cache.

Audio & video calls

WebRTC peer-to-peer calls straight from the inbox. Media never touches our servers — just signalling — and every stream is protected with DTLS-SRTP. Native CallKit integration on iOS so incoming calls ring the lock screen.

Calendar · Notes · Contacts

Built-in CalDAV calendar with invite handling, rich-text notes, and an address book that auto-captures people you mail. Import your iPhone contacts in two taps. All cross-referenced with the unified inbox.

Pro-grade anti-spam

Every inbound message is scored by Rspamd against Spamhaus, SURBL, URIBL, SpamCop and Barracuda blocklists, plus Bayesian and neural network filters. Postscreen rejects known botnets at the TCP handshake before they waste a byte.

No ads. No mining. No AI training.

Your mail, chat, calls and calendar are not used to sell ads, train language models, or build a profile of you. Remote tracking pixels are stripped by default, external images are proxied, and there's no third-party JavaScript on the webmail.

Hosted in the EU

All data — mail, attachments, chat, calendar events, notes, contacts — lives on servers inside the European Union and is covered by GDPR. No secondary storage in US clouds, no CDN replication of private content.

Native iOS app

First-class SwiftUI app with CallKit integration, APNs push notifications, CallKit call handling, offline chat cache, contact import from the iPhone address book and a compose sheet that matches the web. The web UI works everywhere else.

From setup to first call in under a minute.

No servers to run, no command line, no migration script. Sign up, add the mailboxes you already have, and start using everything at once.

One-click presets for Gmail, Outlook, iCloud, Yahoo, Proton Bridge, Zoho, GMX, Yandex, Fastmail and AOL. Or hand-roll any IMAP/SMTP host. Credentials are encrypted at rest with application-level AES before they touch the database.

Mail · Chat · Call · Meet

Compose with a rich editor, start an encrypted 1:1 chat, tap the phone icon for an audio or video call, book a meeting in the built-in calendar. Same account, same sidebar, same notification stream — and on iOS, the same app.

What we do. What we will never do.

Email providers love weasel words. Here's the plain version — no "zero-knowledge" marketing, no PGP theater, just the actual product.

What Tacitus does for you
  • Deliver mail in and out of @tacitusmail.com with STARTTLS on every hop, DKIM signing and DMARC/SPF alignment
  • Encrypt your account password with Argon2id and your stored mailbox credentials with AES before writing to Postgres
  • Score every inbound message through Rspamd + Spamhaus + SURBL + Bayesian and drop obvious spam before it hits your inbox
  • Scan every outbound attachment with ClamAV
  • Strip remote tracking pixels from inbound HTML and block external images until you ask for them
  • Automatically encrypt outbound mail with PGP/MIME (RFC 3156) when the recipient publishes a public key via WKD or keys.openpgp.org — works transparently with ProtonMail, Fastmail, Tutanota and any OpenPGP-compatible provider
  • Encrypt your 1:1 chat end-to-end with the Olm double-ratchet — the server only sees ciphertext
  • Route your audio & video calls peer-to-peer via WebRTC with DTLS-SRTP — media never crosses our servers
  • Host everything — mail, chat, calls, calendar, notes, contacts — inside the European Union under GDPR
What Tacitus will never do
  • Serve ads inside your inbox, calendar or chat
  • Sell or rent your data to third parties
  • Train AI models on your mail, contacts, calendar or chat
  • Scan your mail to build an advertising profile
  • Load a single third-party JavaScript SDK into the web client
  • Forward copies of your data to US-based clouds

Honest caveat: unlike your chat, mail bodies are stored server-side (standard IMAP semantics) so search, sync and sorting work across devices. For recipients without a published PGP key, mail is delivered in plaintext over TLS — the industry standard. When the recipient has a key, we encrypt automatically and show a lock badge in your inbox.

Built on a serious open stack.

No black boxes. Every piece of the stack is well-understood open source — the same tools that run the mail for Fortune 500s and Linux kernel maintainers.

Why people pick Tacitus.

Three reasons we hear most often from early users.

I wanted out of Gmail without losing 15 years of archived mail. Tacitus let me plug in my Gmail IMAP side-by-side with a fresh @tacitusmail.com and migrate on my own schedule. The unified inbox is exactly what I was missing.

We stopped paying for Slack + Google Workspace + Zoom. One Tacitus account per teammate covers mail, 1:1 chat and video calls, and the calendar invites actually sync both ways. It's half the price and we finally own the data.

The Rspamd + Spamhaus stack is the same kind I run for my own clients, pre-tuned and behind a friendly UI. I get maybe 2 pieces of spam a week and I've never had to set up a filter. For a privacy service, that's ridiculous.
