Your Mailbox is your Digital Castle

We remove your personal IP address from the headers of your email. Nobody needs to know your location when you send an email.

Yes, your mail is backed up every night and encrypted with an individual key. However, if you leave us, we will remove the key which makes the backup useless.

Yes. We use DNS-based Authentication of Named Entities (TLSA) and DNS Certification Authority Authorization to tell mail servers and browsers about our certificates. This allows browsers and mail servers to verify they are talking to Soverin by verifying the fingerprints of our certificates and the provider of our certificates.

Yes. HTTP Strict Transport Security (HSTS) means we send headers to your browser telling it to always communicate securely with Soverin. If your connection is hijacked and some other site pretends to be Soverin this will fail because your browser will force https. We use this for all our websites including webmail.

2-Factor Authentication (2FA) can be set up for our webmail only. We currently do not offer 2FA for email clients or software running on your private computer, phone or tablet.

DomainKeys Identified Mail (DKIM) signs your emails telling the receiver that your email was actually sent by a system you trust and that it was not modified in any way during transport.

Yes. Our outbound SMTP servers check for TLSA records and honor them, if the certificate of the server does not match the fingerprint provided by the TLSA record we will not deliver the email.
For our inbound MX servers we publish TLSA records for the private key of the certificate, this means DANE supporting servers can check if they are really talking to our servers, secured with the intended certificate.

Yes. We ALWAYS use encrypted connections. We never send emails over unencrypted connections (between you and us, and not between us and mail servers of people you email, especially this last part is important!)

Yes. Domain-based Message Authentication, Reporting and Conformance (DMARC) and Sender Policy Framework (SPF)are used to tell other mail servers who is allowed to send email for our and our customer domains. It also instructs other email servers what to do with emails they receive from other (unauthorized) systems.

We have chosen a provider for our and our customer domains which provides Domain Name System Security Extensions (DNSSEC) support. This means all domains maintained by Soverin are secured and DNS Spoofing becomes a great deal more difficult.

Everything is hosted in servers that are separately located within Europe, with secured infrastructure and disc encryption in case our hardware is ever confiscated. We select our hosting providers based on our strict privacy requirements.

We have chosen Let’s Encrypt as our certificate provider. Let’s Encrypt is a non-profit certificate authority with a very good track record. A green/verified certificate on our website, dashboard and webmail gives you a way to verify which company is behind Soverin (Soverin B.V.).

Besides for personal use, we cater to hosters, ISP’s, independent professionals and small businesses; so if you need to use your private email for business purposes, Soverin allows you to purchase and manage multiple mailboxes, so you can assign them to members of your team(s).

We want to make things easy for you, so when you sign up with Soverin, you will only be charged annually. You pay once and don’t have to worry about monthly recurring costs.

No, but if after signing up with Soverin, you are not happy with us, we offer a 30-day money-back guarantee. We will fully refund you for your mailbox. All you have to do is cancel within the first 30 days of signing up. We are unable to refund you for any domains purchased as you get to keep these.

Yes. To learn more about how it works, check out our Help page.

Signing up is easy. It’ll take you no more than 5 minutes to complete the five steps to get you up and running. All you will need is a mobile phone number to sign up. And don’t worry, we only use it to reset your password.

Signing up with Soverin using your chosen your own email address on a domain comes at a starting price of €52 total per year for your mailbox and domain. This price is based on a .nl domain which annualy costs €13.

Most email providers have a lock-in. Since most of them don’t offer custom domains, if you join them you will get an email address with their subdomain (for example, Hotmail, Gmail, Yahoo, etc). However, with Soverin, you can easily move your own domain and email address. You can easily import/export your emails and take them with you. With Soverin, your email and domain are truly yours.

Not only do we guarantee that your emails remain private and your personal data is not sold, we also provide you with the same experience you are used to with other email providers. You will be able to sync your email, contacts and your calendar. You get 25GB of storage, and unlimited aliases for free. We also offer personal support through email.

‘Free’ email providers sell your personal data to advertisers. Your private messages are scanned for relevant keywords and the data is sold to advertisers. With Soverin, you get the same experience as you would with any ‘free’ email provider, except that for us privacy comes first. We started Soverin because we value privacy. The information in your emails is for your eyes and the intended recipient only. We will never track your information and sell it for profit

Data has turned into a valuable asset in our digital world, used to invisibly steer our lives. Think about what’s in your inbox. It holds the most intimate details of your life, it’s like a database of your life. That personal data deserves to be protected. What’s it worth to you?

Whether you have (or buy with us) your own domain, you can add as many aliases as you'd like, free of charge.

Yes. You can share your storage and buy additional mailboxes on your own domain for only €10 per year. These additional mailboxes get the same features, options and support you are used to from us. You can buy additional mailboxes in the domain section on your dashboard.

Yes, importing a mailbox is easy. After signing up, all you need to do is import the mailbox you would like from your Soverin dashboard and we will start moving your files. If you need help, our Support team is ready to help!

No, We get paid by you, not by advertisers, so we do not read your email for any purpose (except automated spam prevention). As privacy is one of our core principles, we will never use advertising as a source of income and we will never sell Soverin to a company that does.

We provide access to unlimited email addresses based on your one single email account either by plus-notation or domain-notation and they will still get delivered to your inbox. Find out more information on our Support page.

Deleting actually means deleting. When you delete an email, folder or entire mailbox (also from the trash can) it is really gone, we do not keep your deleted email.

Most people and companies set up email addresses to reflect individuals’ names: whether it’s a first and last name, first initial and last name, etc. In your own domain, this is even more the case. But sometimes you just don't want to share this information. That's why you get a free randomly generated alias for your mailbox on our @sinenomine.email domain that can not be tracked back to your real email address. It does, however, deliver emails sent to it in your mailbox.

Each mailbox stores email with its own login, whereas an alias is simply a different name for an existing mailbox.
