NotiSpark

Features

Everything email should have been.

NotiSpark brings read receipts, a self-sorting inbox and a private AI together in one friendly app for Windows, Linux and Android.

Know when your email is opened

No more “did you get my email?”. NotiSpark lets you know when the emails you send are opened, so you can relax, or follow up at just the right time. Sign in once and it works, on by default (you can turn it off anytime in Settings › Email tracking): no plug-ins, no setup, nothing for the recipient to do.

An inbox that sorts itself

Smart Inbox puts real people and important mail at the top and folds newsletters and notifications into tidy cards. Clear a whole card in one click.

The easy, private calendar for home and work

Type “Dentist tomorrow 3pm” and it's on your calendar, with a little tooth icon. Behind that simple start is a powerful calendar: repeats for real life, invitations with answers, tasks and meeting notes, right next to your email on your computer and your phone. And it stays private: your calendar lives on your devices, not in an ad company's cloud.

An AI assistant that keeps your email private

NotiSpark’s AI runs on your own computer. It drafts replies, summarizes long threads, spots meetings and writes you a morning briefing, without sending your email to anyone.

AI help with nothing to set up

NotiSpark AI is an optional online choice, next to the AI on your computer and your own AI account. Turn it on once and it works right away, on your computer and on your phone. Nothing is sent until you choose it and start an action, and each action uses a credit or two.

Your inbox and calendar in your pocket

A little show when new mail arrives

Bring your IncrediMail notifier collection: import the folder you already have, and your animations play again when new mail arrives. Or use Spark letter, included with NotiSpark, or make your own from a GIF and a sound. Prefer it quiet? Keep the small desktop notification instead.

NotiSpark Sync: your signatures, contacts and settings on every device

Your signatures, contacts, calendar and settings on all your devices — end-to-end encrypted. Change something on your office PC and see it on your home PC and phone. Everything is locked on your device before it leaves, so only your own devices can read it.

Encrypted email, made simple

Some emails are meant for one person only. NotiSpark opens encrypted mail for free, and on Pro and Business you can sign and encrypt the mail you send, with S/MIME or OpenPGP. Your keys stay on your devices, not on our server.
