GravesMail
GravesMail brings all your email accounts together in one Windows app and keeps them safe from spam, phishing scams and dangerous attachments.
🛒 Get GravesMail Available now for Windows. macOS, Linux, iOS, and Android coming soon.It works with Yahoo, Gmail, Outlook, iCloud, AOL, Zoho, Fastmail, GMX and any standard IMAP/SMTP account, including secure sign-in for Outlook. Your mail is copied into an encrypted store on your PC, so after the first download you can read, search and organize it even without an internet connection.
Private by design. Nothing about your mail is sent to GravesWare or anyone else; the mail server is used only to fetch new mail and to send. The spam filter learns from your mail only on your own PC, and GravesMail never deletes mail from the server unless you turn that on.
Key Features
7-Layer Spam & Malware Detection
Seven independent Protection Layers examine every message: domain validation, a learning Bayesian filter, header authentication, heuristic scoring, sender reputation, your system antivirus, and YARA malware scanning. If any single layer raises an alarm, the message is treated as spam — no averaging, no single score to slip past. Detects trojans, ransomware, malicious macros, and phishing documents.
Quick Rules — Intelligent Triage
Create one-click rules that set mail aside in the Spam Trap, move it, or auto-delete it. Rules grow smarter as you use them — apply one to a sender and that sender is added to the match list automatically. Review everything your rules caught in the Filtered list, where Safe Preview lets you read a caught message safely — and reply or forward it — without restoring it first. Scan entire folders in seconds.
Large Mailbox Support
Your newest 500 messages load in under a minute. The rest syncs quietly in the background while you work — even mailboxes with 100,000+ messages. Pause, resume, or stop anytime.
Automatic Encrypted Backups
Scheduled full and differential backups of your whole profile — not just mail, but contacts, calendar, rules, lists, filter training, and keys. AES-256 encrypted under a key GravesMail manages, so no password is needed day to day. Set a recovery passphrase once and your backups can be restored on a new or replaced device. Every deleted message is captured for 90 days.
End-to-End Encryption (OpenPGP)
Real, standard OpenPGP — sign, encrypt, and read encrypted mail with anyone using PGP on any mail system, not just other GravesMail users. Generate or import keys, verify fingerprints, and link a key to a contact so encrypting just works. Proven to interoperate in both directions with GnuPG, the reference PGP implementation. PGP encrypts the message body and attachments; it does not hide the subject line or who you wrote to.
Password-Protected Email
Send a private message to anyone — no keys, no accounts, no GravesMail required on their end. Your message and its attachments are sealed inside a real AES-256 encrypted ZIP that opens with free, ordinary software like 7-Zip or Keka on any platform. You share the password separately, by phone or text. It’s the industry-standard archive format — proven to open with real standard archiver software, not a GravesMail-only container.
55 Languages
The interface ships in 55 languages, each listed in its own script. Arabic, Persian, Urdu, Sindhi and Uyghur lay the whole window out right to left.
External Image & Tracking Pixel Protection
External images blocked by default to prevent IP tracking. Tracking pixels stripped to prevent read receipts. Independent controls — load images without loading trackers.
Local-First. No Cloud.
Every email stored on YOUR computer in an encrypted SQLite database. No accounts to create. No subscriptions.
Five Platforms. One Experience.
Windows (code signed), macOS (Apple Silicon), Linux (x64), iOS, and Android. Same privacy-first approach on every platform. Desktop versions are full-featured; the mobile app brings your local inbox to your pocket.
Filter That Learns
Every time you mark a message as spam or safe, the filter gets smarter. It ships pre-trained on a large corpus of real spam and legitimate mail, and builds on that baseline as you use it. Learn more →
