Key Features

Private and Secure

Inky's own servers never touch your mail. Inky runs on your computer or device and downloads the mail directly from your provider, so your mail never goes through our network or computers. Inky encrypts all your data using AES-256-GCM encryption, and is suitable even for classified contexts requiring S/MIME, FIPS, and NIAP certifications.

End-to-End Encryption and Digital Signing

End-to-end encryption means that email content is encrypted before leaving one user's device (one endpoint) and is not decrypted until it arrives at another user's device (the other endpoint). Digitally signed email contains the equivalent of a digital signature so recipients know they can trust the message came from who it says in the From: field.

Connect to Any Email Account

Inky supports Office 365, Microsoft Exchange, Google Apps, GMail and other IMAP servers. Where many popular email readers only support the big email providers, Inky goes further to ensure that you can access all of your accounts from one unified interface.

Office 365 & Microsoft Exchange Calendar Support

Stay up-to-date with events connected to your Office 365 or Exchange accounts with Inky's integrated calendar. You can create and edit events, as well as respond to meeting requests, all from within the same interface where you manage your email.

Cloud-Based Settings Profile

Take your email accounts with you. Inky makes the most of the cloud, by seamlessly syncing data, message flags, and tags across all your devices. And setting Inky up on a new device is as simple as downloading the app and logging in.

Advanced Searching and Filtering

Inky proactively retrieves, analyzes, and indexes messages from your mail servers, which means searching even a hundred thousand emails happens instantly, as you type — even when you’re offline. And you can search by tags as well as by header/body text.

Unified Interface

Viewing email in Inky is simple and frictionless. Access the same time-saving features on all your Windows, Mac, iOS and Android devices. Your custom mailboxes and other settings sync seamlessly to all your Inky instances. So you can set up a mailbox on desktop and have it instantly update on your phone.

Sort By Relevance

Inky's unique relevance sorting lets you read messages in order of importance. Email messages from close contacts have a vibrant blue drop and rise to the top of your message list. Less important mail and spam messages appear faded and sink to the bottom.

Email Synchronization

Inky keeps your emails in sync with your email provider. For example, if you read a work email message, and then go to the office, you will see that message is marked as read there as well. And tags you assign to senders or messages are automatically synced across devices as well.

Smart Sending

Inky helps you make sure you send your email from the right account to the right person. Inky will suggest people to add to an email if you frequently include them in a group. Inky will also warn you when you're about to send email to someone for the first time, just in case you've made a typo.

No New Email Address Required

Inky is not a new email address; it's a better way to pull together all your existing addresses, which stay as they are.

Inky is Flexible

If necessary, you can switch back and forth between your providers' websites and Inky anytime. You can also add as many existing email accounts as you want.
