Bmail is end-to-end encrypted email built around your keys, not someone else's policy. Every message you send to another Bmail user is sealed with X25519 + XChaCha20-Poly1305 before it leaves your device. The server stores ciphertext. We can't read your mail, and neither can anyone with a subpoena. WHAT'S INSIDE • Encrypted email with PGP and S/MIME interop, so you can keep talking to people on Gmail, iCloud, and Outlook • Calendar, contacts, and Drive — all encrypted, all backed by the same keys • Custom domains: bring your own domain (you@yourcompany.com) and get the same encrypted pipeline • Push notifications that don't leak content — only "you've got mail" • Account recovery via BIP-39 mnemonic phrase. No phone number, no security-question theatre, no PII collected HOW IT'S DIFFERENT • The server runs inside Intel SGX enclaves. Even the operator can't peek at session keys • Authentication uses OPAQUE (RFC 9807) — your password literally never touches our servers in plaintext • Source is published. The server you're talking to and the WASM crypto in your browser are reproducible from the open repo at github.com/bmailag/bmail • Built by VP.NET. We don't sell ads and we don't sell mailbox metadata PLANS • Bmail: encrypted email + calendar + contacts + Drive + custom domains, with 100 GB encrypted storage. Available monthly or yearly Part of the VP.NET Family PRIVACY We only store what we need to deliver your mail. No tracking SDKs, no analytics, no third-party advertising IDs. Recovery is by mnemonic phrase only — we never collect a phone number, identity document, or backup email. TERMS OF USE https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Inbox Imp

Inbox Imp reads your mail so you don't have to. Gmail and Outlook. An AI assistant sorts every incoming email: advertising gets filed, cold pitches go to their own pile, and the handful of messages that actually need you stay in a short, quiet queue. The app shows you that queue: who wrote, what it's about, and why it's worth your time. Clear each message with one swipe. Every inbox you own, one membership. Connect Gmail, Google Workspace, Outlook.com, Hotmail and Microsoft 365 addresses under one account. - Rules you can read: a plain-English page says how your mail is handled, and you can edit it - Safeguards above the AI: login codes, real replies, receipts and money mail, calendar invites and account notices stay in your inbox - Archive, never delete: filed mail stays searchable; only clear junk goes to Trash, recoverable for 30 days - Every action is logged with a reason, one tap to undo, and a Recently archived list to review - "Why you got this" on every message it keeps - Reply, forward and compose with dictation, attachments and AI drafting help - Catch up on a long thread in one line per message - Push roundups instead of a ping for every email; urgent mail still comes through - Ask your mail anything: search that answers questions, not just keywords - Spending: what you paid, by merchant, from your receipts Try Inbox Imp free for 7 days; no payment details needed to start. After the trial, an Inbox Imp membership is $9.99 per month (auto-renewing, cancel anytime in Settings) and covers all of your inboxes.
