All the power of running your own private mail server without having to do so.
Now celebrating 26 years of service!
Don't let our basic, matter of fact, website dissuade you from checking out our very modern and full featured mail service. We don't dedicate our time to looking corporate on our web site (we've been doing this a very long time), We dedicate our time to providing a very robust, modern, well supported service. There is a free 30 day trial, no card or email address required, for you to experience it, yourself. Take us for a test drive, see the difference.
If support is important to you then you have come to the right service! Rapid personal support is a hallmark for us. Our own devs rotate on helpdesk, which ensures that you are not only receiving knowledgeable support, but support from someone who can fix your issue right away! We do not offer free accounts, this means we are totally focused on our subscribers and not innundated with the issues that stem from offering free accounts.
We are not interested in being a discount service, although you will find us mostly competitive. We offer what others do not, not only in features, but in personal attention and support. We implement feature requests rapidly where appropriate. Our entire staff rotates on helpdesk, ensuring your helpdesk request is competently and rapidly handled. We might cost a dollar or two more a month, but what we offer is worth it.
Ever dreamed of blocking emails from entire countries at once? Or just blocking all messages from specific top-level domains like .sbs, .world, or any others cluttering your inbox? Imagine being able to automatically filter messages in languages you don't understand, or selectively disable an email address while still receiving messages from your important contacts.
What if senders received a definitive "User Unknown" rejection at connection, not just silent filtering that hides unwanted mail in folders you never check? And what if accomplishing all this required nothing more than clicking a button? These capabilities represent just a small sample of what our service offers. In fact, if you can envision a solution for managing your email, chances are we've already implemented it.
- Never worry about email address leaks again: Create unlimited email addresses across 30+ domains, each with its own subdomain catch-all addressing. Give unique real email addresses (not randomly generated aliases) to every service and instantly identify who leaked your email. If spam starts arriving, shut off just that address without affecting any other mail. It's a built in aliasing service on steriods.
How to categorize your mail while using unique addresses for everything! - Instantly stop unwanted messages at the server level: When you block an address or turn off an alias, our system rejects those messages during the SMTP handshake as "User Unknown." Senders believe your address no longer exists, permanently removing you from their lists.
- Protect your true identity online: Create addresses that can't be linked back to your account, allowing you to segment and categorize your email while enhancing your security. It's like having unlimited email accounts! Your email address no longer needs to be a unique identifier for your online presence!
An email address getting leaked because some site you gave it to was compromised no longer needs to be a concern! - Use your own domains with all our powerful features: Host as many personal domains as you want, each working seamlessly with our complete feature set. Control them as catch-alls or whitelists where only addresses you specify are accepted. Yes, you can even have mail with your own domain rejected at the connection when you block it!
- Access your secure email from any device: Our webmail works just like an app and will adapt its form factor to whichever device you are using (phone, tablet, or computer). It is compatible with uBlock Origin, DuckDuckGo, Brave, LibreWolf, Firefox, Safari, Edge, Chrome, Mobile Safari, Samsung Internet, and frankly, most modern browsers (mobile and desktop). Our server-side controls mean our features will also work with your preferred email application.
- Integrate with your existing email setup: You can also integrate our service with your existing mail a number of ways: you can add us to your multiple mailbox app of choice; you can easily forward all mail to your main account after it passes through our features; or you can use us, just like any regular email app, to retrieve via pop or imap (including automatically PGP/GPG encrypting as it is retrieved, if desired) and also send mail using your other account(s) SMTP server with privacy.
Nobody gives you more control of your e-mail than we do!
Need or want to add encryption?
Zero Access & Zero Trust Architecture
- Your eyes only - truly private storage: You choose whether or not to automatically PGP/GPG encrypt your incoming mail with keys that only you possess, meaning that only you can read your sensitive content. Mailvelope compatible.
- Encryption your way: Choose what incoming mail gets automatically encrypted and with which public keys, balancing security and convenience. Automatically encrypt all, only specific addresses, or by filter action. Meaning, if you only want to secure your sensitive mail, you can do that. Your mail, your keys, your choice!
- End-to-end encryption for your most sensitive messages: Easily use standard PGP/GPG with any other user on any other service also using PGP to ensure that only those with the keys can read messages, maintaining privacy from end to end. Standards based means it doesn't just work if you are both on this service, it is service independent.
- Secure Link: You can select to send a link to an encrypted file instead of an attachment for secure file sharing. Files are encrypted using AES-256-GCM on your device and the encrypted content then is uploaded to our server and a link is put into the email for secure retrieval by the recipient. You will be notified of downloads.
- Complete data portability and freedom from vendor lock-in: Easily import and export everything (mail, encryption keys, calendars, tasks, address books, and even filters) using standard formats, maintaining full control of your information. Encrypted e-mail is exported fully encrypted, nobody but you can read it in or out of our service (you could export it and post it to the web and you would still be the only one that could read it's content). That is zero access!
- Built on open standards you can trust: The entire service is built from and runs on widely used standard open source software. Standards matter, You should never be tied to any one service, standards based means easy import and export of any or all data as needed.
Email security based on standards, not promises
