Learn about LuxSci WebMail

Watch a brief tour of LuxSci WebMail

Perhaps you were wondering...?

We include technical support with all accounts. LuxSci's support staff are located in the USA and are all US citizens. Standard support hours are 9am to 11pm Eastern Time, USA. During this time, our staff is standing by to answer your questions via email, support ticket, and phone. Emergency, mission-critical support is available 24/7/365. (Read more about LuxSci Support.)

In addition to SecureLine for email encryption, LuxSci provides a range of security features including two-factor login, password expiration, opportunistic TLS for inbound and outbound email, email header scrubbing, login auditing, custom firewalls, customizable session timeouts, and more. (Read more about the LuxSci security and privacy focus.)

LuxSci email works with any email program on any computer or mobile device, including Outlook, Mac Mail, Thunderbird, and the default email programs in iOS and Android. LuxSci email and SecureLine email encryption work through secure IMAP, SMTP, and POP connections from your programs to the server. There is never any need to download special programs, apps, or plugins. Additionally, LuxSci provides an option for using ActiveSync for real-time synchronization of email, contacts, calendars and more with your mobile devices and recent versions of Outlook/Windows Mail.

LuxSci includes 7x daily on-site and 4x weekly off-site backups of all of your email, Web, and other data. You can request free restores as needed, although very frequent or very complex restore requests may incur a surcharge. (Read more about backups at LuxSci.)

Daily and weekly snapshots also protect your sensitive data against server failure, and we can always restore all your data. (Read more on LuxSci infrastructure and reliability.

LuxSci also offers Email Archival for saving copies of all inbound and outbound email. These copies cannot be edited or deleted by anyone. We save them for up to 10 years.

A shared business-class email hosting account comes with 50GB of disk space that you share among all your users (we do not limit space on a per-user basis although you can opt to impose such limits). If you exceed your limit or want to buy more space, we charge $0.75/GB. (Read more at Business-class vs Enterprise Class and Standard Shared Hosting: Disk space limits.)

Dedicated server customers can get from 10 GB up to 9000 GB of space per server. Dedicated is the way to go if you have large-scale storage needs.

LuxSci permits you to send and receive email messages that are up to 200 MB each (for customers with Email Archival, the limit is 50MB/message).

Email hosting customers can send up to 300 email messages/day; customers can send each message to up to 1000 recipients. These messages are not for use with bulk emailing of any kind (See our acceptable use policy).

For email marketing and large-scale sending needs, we offer a separate High Volume service. We can add this additional service (and the associated cost) to your business email hosting account.

There's no explicit limit on the number of messages you can receive. However, the receipt of large quantities of messages all at once (many 100s or 1000s of messages at a time, for example) can cause your inbound email to suspend automatically to protect our servers from inbound email abuse and "mail bombs." If you need to receive large numbers of messages in a short time, LuxSci provides dedicated inbound email processing servers.

There are no limits on the number of users who can be in your account or the number of addresses you can have in your address book.

We don't limit the number of messages you can store in your email folder. It's important to note, however, that larger folders are slower to use than smaller folders (more than 100,000 messages would be extremely slow) and no email folder can contain more than 1 million messages.

The majority of our servers are located in the state of Texas, USA. Customers ordering dedicated servers can request that their servers be in other areas of the USA, London, Sydney, or Hong Kong.

LuxSci has an automated email migration service for transferring the email folders for all your users. (For more details, see Migrate Your Data to LuxSci.)
