YouniqMail isn't for everyone—it's for anyone who finally wants to adapt their inbox to their work style and workflow, without compromising your privacy

All data is stored local - no YouniqMail servers involved

While other mail apps route your messages through their servers, YouniqMail keeps things private by connecting straight from your device to your email provider. (We don’t even have any servers, except the one on which this website and our public email tools run 😉)

We just want your money and feedback - not your data

We know that not every user needs the premium functions. That’s why YouniqMail has a simple Freemium model. So YouniqMail don’t collect any and share any personal data with third parties.

Highly customizable - adapt to your work/-mailflow
Every user has different workflows for their email management, which is why YouniqMail is highly customizable and doesn’t force workflows on you.
Supports IMAP and SMTP (also Gmail, iCloud...more soon)

There are so many mail and hosting providers, that´s why YouniqMail is design to work with most of the IMAP and SMTP providers, not just one. Also currently supporting Gmail, iCloud, Yahoo, GMX and WEB.DE. Support for more providers will follow soon.

Compatible Flags-System

You may know it from Apple Mail: The ability to organize / categorize your mails with colored flags. Compatible with the Flags from the Apple Mail Client and Spark’s (orange) pinned feature.

Basic categorization & sorting

Your mail list has basic categorization for read, unread and has attachments. You can also sort them by newest / oldest first or largest / smallest first (maybe we add some more sorting options soon).

Complex search & filter options

Don’t worry: you will find your mails with the YouniqMail Search and multiple filter options.

Relax & take a snooze

Organize your inbox with the snooze function: Select a predefined date and time or set a custom time. Select if you want to get a system notification when the mail unsnoozes.

Smart attachment handling

Easy to use and convenient handling of attachments. You get previews, some meta information like file sizes and file type and easy save to your disk. When sending attachments you can easily resize the images before sending.

Full contact management & contact details off-canvas

Organize all your (mail) contacts in the contacts window. It already supports sorting, filters, searching and bulk editing.
Also including a companies and groups system for your contact.
If you click on a contact the contact details off-canvas will open. 

Full attachment management

Like the contact management there is also a management and overview window for all your attachments. Quickly find and download attachments with sorting, filters, searching and bulk actions. You can also quickly open the associated email.

Add notes to emails

You can add notes to your emails and of course they get marked with a note icon and can be found in a special grouped mailbox.

Automations / rules system

Create your own automations / rules for new mails to organize and manage them quickly. You can choose from a lot of conditions and actions, but we will constantly add new options.

Keyboard shortcuts system

A frequently expressed wish: keyboard shortcuts or operation via keyboard. So YouniqMail already has a basic and configurable keyboard shortcuts system. We will expand and improve this in the future.

PGP support

To fully utilize all the advantages of local storage and data privacy, YouniqMail has started supporting PGP. It’s still very experimental; we welcome testers and feedback.
(S/MIME support will also follow)

Frequently asked
questions

I always want to develop very closely with the community/users, so I’m looking forward to a lively exchange with you. The alpha phase started on 14th December 2025, where everyone is invited to test the email client and give feedback. Of course the alpha and beta phase will be free for everyone.

Follow the development updates on the feedback platform (https://feedback.youniqmail.com).

The price for the Premium subscription will be announced soon. Of course there will also be a Beta / Early Bird discount.

Of course, the beta and alpha phase is free of charge. Your early stage feedback is worth more than money.

YouniqMail uses IMAP, therefore all modern IMAP providers are supported. Since 12th October Gmail (with label Support) and iCloud is also supported. The plan is to support other well-known email providers such as Yahoo and Microsoft 365 / Exchange as soon as possible.

No, POP3 Support is not planned. But if there is a high demand for it, it will be considered for the roadmap.

YouniqMail is currently being developed for macOS, Windows and Linux.

At the moment, only a desktop app (for Mac, Windows and Linux) is in development. If the response is positive enough, I will endeavor to develop a mobile app, but this will not be available at launch.

To a certain extent, offline support already exists because all data, such as emails, contacts, attachments, etc., is stored and accessed locally on your device. Therefore, some features will also be available offline. Further details will be specified in the future. Depending on user demand, I will consider how much we can expand offline support.

Hi 👋, I’m Sven and I started developing YouniqMail at the beginning of 2025.
In my search for an e-mail client that is data protection compliant and does not send all mails or other data via the developer’s servers, I hardly found any mail clients that came into question. Even when I did find one that could be considered, it forced you into certain ways of working and/or was not customizable enough.

So I had to start developing my own email client that was based on the three main pillars
1. privacy compliant
2. does not send data to the developer’s servers,
3. is highly customizable and offers more features to organize your mails – so you can etablish your own email workflow.

I firmly believe that every user has different workflows for their email management, which is why YouniqMail should be Younique for every user.
