You have questions, we have answers.
At the moment, users are limited to sending 2 emails per minute and free users can create a maximum of 20 custom aliases. This is to prevent spam and abuse on the service. To increase the custom alias limit, join our Patreon.
Horizon Mail's invite system prevents a massive influx of user signups. As a result, Horizon's servers are never overloaded and abused less.
Our IMAP, POP3 and SMTP servers are at mail.hrzn.email. IMAP uses port 993 (SSL), POP3 uses port 995 (SSL) and SMTP uses port 587 (STARTTLS). Supply your full email address ([email protected]) as your username and your login password as your password.
Many users often forget to append @hrzn.email to their username on our webmail client. Ensure your username is set to your full email address and try again.
You can reset your own password using your recovery code. If you have disabled account recovery or lost your recovery code, your account cannot be reset.
Please send an email to [email protected] requesting account deletion. We will then permanently delete your Horizon Mail account as well as all associated information, including emails. This is irreversible.
No. Horizon has never, does not and will never sell user information. We strongly dislike this industry practice and are morally against doing so.
No, Horizon does not track its users.
Emails are encrypted in-transit using SSL for incoming and STARTTLS for outgoing. This prevents your ISP and potential network eavesdroppers from snooping on your emails. On our servers, your emails are stored server-side encrypted with a master asymmetric keypair. While we have the keys to decrypt email, we will not pry into user inboxes to preserve privacy.
If you do not trust Horizon with your emails, consider using an open-source technology, such as PGP/GPG encryption, to end-to-end encrypt your emails. This prevents anybody except for you and a recipient from reading the contents of your emails.
Horizon servers are located in Germany. We store data in this location to cut down on server costs and to apply General Data Privacy Regulation (GDPR) laws to user data. This gives us more financial resources while benefiting your privacy.
We follow many security practices to ensure your data does not end up in the wrong hands. The following is a list of some of our protocols:
We have many more protocols in place other than what is listed to secure user data. We take security seriously and try our best to restrict access to user data.
Passwords are never stored in plain-text on Horizon. Horizon Mail first hashes your password with an individual salt using the SHA512-CRYPT algorithm specification. This creates a representation of your password which cannot be reversed. In the event of a data breach, your password would not be exposed due to it being hashed before being stored. Nobody, including Horizon developers and operators, can view your password.
A Horizon alias is a separate Horizon address that forwards all of its emails to your inbox. This can be useful to compartmentalize each of your different newsletters of services. Generating a random alias for each service gives you the ability to cut off communication with that service at anytime by simply deleting its alias. This can also be of use after a service becomes victim to a data breach. Your alias would be in the data breach, not your real address.
When you delete an alias, it will no longer receive emails and it can never be re-used again by anybody. This is to prevent impersonation.
