Built for people who actually live in their inbox

Email that feels smart, fast, and under control.

BlackMail is a next-generation iOS email client for people who do real work in their inbox. Saved searches, smart folders, AI-assisted replies, and offline access—wrapped in a familiar Mail-style interface that doesn’t fight you.

Designed for multi-account power users, executives, and anyone who wants fewer inbox surprises.

Feature overview

Everything you need to stay ahead of your inbox.

BlackMail isn’t just “another email app.” It’s a full set of tools for searching, organizing, responding, and staying informed—without losing the straightforward feel of classic Mail.

Focus without hunting

Personalized Saved Searches

Turn your favorite searches into living views—“Invoices this month,” “Customers waiting on me,” or “Unread with attachments.” BlackMail automatically surfaces new matching emails without you rebuilding filters every time.

Pin saved searches to the sidebar for true one-tap focus on what matters.

Search that makes sense

Guided Advanced Search

Build precise searches with simple all / any / none toggles. Add effortless date, account, or attachment filters and see results update as you refine. No cryptic syntax to remember—just clear, guided controls.

Search across subjects, senders, text, and files in a single view.

Travel-proof inbox

Full Mailbox Download

Choose to keep entire mailboxes and attachments available offline. Whether you’re on a plane, in a dead spot, or roaming, your existing messages and files are ready to search, open, and forward.

Smart background sync keeps local data fresh without draining your battery.

Respond in seconds

AI Reply Assistant

Draft clear, polite replies that match the tone of the conversation—status updates, follow-ups, intros, and more. You stay in control: review, tweak, and send in a couple of taps.

Spend your energy deciding what to say, not typing it out.

Work + life, side by side

One-Tap Multi-Account Switching

Keep corporate, personal, and side-project inboxes in one app without mixing them up. Switch accounts with a single tap and see which context you’re working in at a glance.

Ideal for consultants, executives, and anyone wearing multiple hats.

Familiar, but better

Smart Folder Sidebar

A Mail-style sidebar that mirrors the folders you already know—plus smart folders, saved searches, and VIP views. Drag and drop to tidy up messages without thinking about where anything lives.

Keep your mental model of email, just with more power and less friction.

Threads, not chaos

Conversation View

See entire threads stacked together, with the latest message highlighted and quick actions always in reach. Jump straight to the part you need without digging through your inbox.

Reply, forward, or snooze from inside the conversation—with context intact.

Quietly always current

Always-On Sync

BlackMail keeps folders and unread counts up to date, even after network interruptions. You get an accurate inbox without constantly pulling to refresh.

Built for reliability on spotty hotel Wi-Fi and busy corporate networks.

Files that don’t vanish

Attachment Gallery

Browse every file sent to you like a mini file cabinet. See previews, open in place, or quickly share without hunting through old threads.

Filter by sender, timeframe, or account to find “that PDF” instantly.

Professional message composer

Smart Compose Window

Address chips and suggested contacts make sending to the right people effortless. Add inline images, clean quoting, and rich formatting so your messages look as polished as you do.

Built to feel like a serious desktop-class mail composer on your phone.

Trust, but verify

Outbox Monitor

See pending messages, retry progress, and clear send-status indicators in one place. When a network hiccup happens, you know exactly what’s still on its way.

No more guessing which messages “probably” went out.

Notifications you can live with

Custom Alerts

Make each folder—or VIP sender—behave differently. Loud alerts for critical projects, gentle badges for low priority, and quiet time when you need to focus.

Craft an inbox that respects your attention instead of stealing it.

One bar to find it all

Global Search Bar

Search across all accounts, folders, people, subjects, message bodies, and attachments at once. Shortcut into it from anywhere and get to what you need in seconds.

It’s like a command palette for your entire email life.

Security by design

Face ID–Protected Vault

Sign-ins and tokens are kept in a secure credential vault protected by Face ID. You stay signed in across accounts without re-typing passwords all day.

Your email stays convenient and locked down.

Triage at thumb speed

Personalizable Swipe Actions

Configure swipe gestures for the way you actually work—archive, move, flag, mark as waiting, or schedule follow-up. Clear dozens of messages in a couple of passes.

Make your thumb the fastest part of your workflow.

Inbox as to-do list (done right)

Snooze & Reminder Tools

Push conversations out of your way until you’re ready. Bring them back next week, tonight, or “when I’m at my desk” so nothing important slips through the cracks.

Let your inbox remember for you instead of keeping mental tabs.

Action-item radar

Mention Highlights

Automatically pull emails where you’re @mentioned or clearly assigned work into a focused follow-up list. See what needs your response, separate from general FYIs.

Skim less, act more—especially in noisy team threads.

Battery-friendly freshness

Battery-Smart Background Fetch

BlackMail keeps new messages ready without hammering your battery. Fetch strategies are tuned for iOS so you stay in sync without your phone running hot.

Built for real-world devices, not just lab demos.

Clarity about your email life

Insight Dashboard

See mailbox usage, top contacts, response times, and backlog trends in plain language. Spot where work gets stuck and where you’re over-or under-investing attention.

No charts for chart’s sake—only insights you can actually act on.

Start the day ahead

Executive Daily Digest

Wake up to a concise summary of important conversations, open loops, and key deadlines. One skim in the morning and you know what deserves your attention first.

Ideal for busy leaders and anyone who wants an inbox briefing, not a firehose.

Workflow

Built for people who actually live in their inbox.

BlackMail is designed so you don’t have to relearn how email works. It honors the habits you already have, then adds power where you’ve always wanted it—search, triage, follow-ups, and insight.

From install to “I can’t go back” in three steps.

  1. Connect your accounts. Add your work, personal, and side-project inboxes. BlackMail keeps them clearly separated but easy to switch between.
  2. Save your key searches. Turn the queries you run every day into Smart Folders and Saved Searches that auto-update in the sidebar.
  3. Dial in alerts and swipes. Tune notifications and swipe actions so triage feels natural and your phone only shouts when it really matters.

Within a couple of days, most people treat their inbox less like an overflowing bucket and more like a dashboard for action.

Designed for high-leverage roles.

BlackMail shines for executives, managers, ICs with heavy stakeholder communication, and anyone running multiple roles at once.

  • Leaders: Use the Daily Digest and Mention Highlights to stay on top of what your team needs from you.
  • Client-facing roles: Rely on Saved Searches and the Insight Dashboard to keep deals moving and promises honored.
  • Operators: Use Snooze, Reminders, and the Outbox Monitor to coordinate busy days without dropping threads.

iOS-first design Desktop-grade controls Power-user friendly

Insights & privacy

Know what’s happening—without giving up control.

Your email is the map of how you work. BlackMail gives you clarity on that map while keeping security, privacy, and local control front and center. You can read our full Privacy Policy for the deep technical details.

Clear inbox health signals.

The Insight Dashboard and Executive Daily Digest surface the metrics you actually care about: response times, top contacts, backlog size, and threads waiting on you.

Instead of endlessly scrolling, you get a short list of conversations that change your day if you handle them right now.

Security that respects your data.

The BlackMail iOS app keeps credentials in Apple’s Keychain and iCloud-secured storage on your devices, and uses access-less notification mechanisms that do not give our servers full mailbox access.

AI-assisted replies are generated locally using Apple’s on-device Foundation models, so neither we nor Apple receive your message text or the suggested replies.

Your inbox stays fast and powerful on your device—without turning into someone else’s data product.
