Secure High Volume Email Sending for Healthcare

Emails like appointment reminders, medical lab or test results, and many other types of trigger-based emails from health care providers can be an effective way to increase patient engagement and streamline workflows. However, these emails often contain sensitive information or PHI and need to be encrypted to comply with HIPAA. LuxSci's advanced encryption technology is flexible enough to meet any combination of security and usability needs.

SecureLine^TM Encryption Technology

LuxSci's SecureLine^TM encryption engine automatically encrypts every email. It works like this- messages are delivered to LuxSci via API or SMTP and SecureLine^TM encrypts the emails before securely delivering them. SecureLine^TM is extremely flexible and encryption settings can be configured to meet a variety of security, compliance, usability, and deliverability needs.

Secure High Volume Email Sending Features

Every Secure High Volume customer has their own dedicated server or cluster and IP addresses, designed to meet their email sending and throughput needs. The exact specifications will depend on how many emails need to be sent and how quickly they need to reach recipients' inboxes. LuxSci will design a custom deployment based on this information.

Custom cluster solutions provide a dedicated, micro-segmented trust zone that can be tailored for very high volumes of sending, very high throughput, very high security, high availability, and business continuity. They are designed to be Zero Trust-aligned and can be resilient to data center failure.

Email Delivery

(+) show all descriptions

Feature
Use Your Own From Addresses
Reverse DNS (rDNS) records
Reverse DNS records point the IP address of your email server to the server's domain name. This information reduces the risk of the receiving server viewing the email as spam.
Alternate SMTP Ports
Alternate ports for SMTP access: 80, 465, 587, 2025, 6025, and 6465. If firewalls or ISPs attempt to block your messages, sending your email via these alternate ports helps ensure that your messages are delivered.
DKIM - Sign outbound messages
DKIM allows receiving email servers to feel more confident that the email originated from the listed domain, increasing the deliverability of your message.
SPF/SenderID
SPF and Sender ID authentication information is used by receiving email servers that are checking for spam. The existence of this information reduces the chance that your email is blocked.
Anonymous SMTP - IP Masking
Anonymous SMTP hides the IP address of the computer or server that is sending the message. This feature increases deliverability when you are sending from an ISP or location that is blocked or has a poor reputation.
IP Reputation Monitoring
LuxSci checks its server IP addresses to make sure that they are not on block list databases and to immediately alert us of any block listing issues so that they can be immediately addressed.
Graylist and block list resolution
LuxSci works to resolve problems that may have resulted in your IP being gray or block listed.

Reporting

Feature
Messages Sent
This online or emailed report lists successfully sent messages. It can be downloaded, sorted, and searched
Tracking and Deliverability
This online or emailed report lists the delivery status of every message sent to every recipient. It can be downloaded, sorted, and searched. For messages that were not successfully delivered, the delivery issue is listed. Summary reports are available on a daily and monthly basis.
Tracking Soft and Hard Bounces
Automatic tracking of delivery success and failure. Automatic processing of post-delivery bounce messages and updating of message delivery status. Automatic differentiation between "soft" and "hard" failure messages.
Email Delivery Status Digests
This emailed report lists all email delivery status updates for all messages sent to a specified email address or list. It is useful for automating processes and for automatically informing you of issues. It is delivered to you automatically on a frequency that you select (e.g., weekly). The report is sent to your email in HTML and also includes an Excel file for easy analysis.
Email Delivery Failure Reports
This report lists all email delivery failures and includes the reason why the delivery failed. The report is sent to your email in HTML and also includes an Excel file for easy analysis. It can be used, for example, to discover misspelled addresses and to remove non-working addresses.
Feedback Loops (SPAM notifications) with Major ISPs
LuxSci works with major ISPs to quickly detect spamming and other issues and to help keep our servers off block lists. LuxSci users can see SPAM complaints by logging into the system. Users can also have their SPAM complaints automatically sent to their email. Complaining recipients can then be easily removed from their mailing lists.
Auto-block future email to complainers (optional)
For recipients that complain that your messages are unwanted/spam-like, and where those complaints come back through the standard feedback looks from Major ISPs, LuxSci can automatically add the problem recipient email addresses to your domain-wide recipient block list. Thence forward, all email sent to those same addresses by anyone in the same domain will be automatically blocked (and logged). Its your job to make sure that your mailing lists are opt-in and clean and to remove the addresses of everyone who complains in any way. Auto-blocking of complainers is a safety net for you -- even if you make a mistake and send to a complainer ... we will be sure the message is stopped before it gets to them. This feature must be enabled in your domain's outbound email settings page.
Bounce Processing
Open Tracking
URL Click Tracking
Custom Header Tracking & Reporting
Track the values of up to 3 custom email headers added by your sending email system. Use these when searching for messages and generating reports. See these down downloading reports.

Feature
SecureLine^TM encryption for all email messages
Full-disk Encryption
Multiple layers of firewalls
Account isolation: No other LuxSci customers have access to your server. No shared servers.
In a shared solution, many 100s or 1000s of separate customers share the same server. Security replies on logical and software partitioning of access and resources. Shared solutions are inherently less secure, have less consistent performance, but are less expensive. Dedicated servers are recommended for when security and consistent performance are important.
Backups included?
Custom backup/retention schedules?
Dedicated server customers can choose custom backup frequencies and retention schedules; this may come with an additional cost. Contact sales for more information.
Access controls and audit logs
SMTP username & password authentication
FIPS-Approved TLS connections to SMTP
LuxSci provides the following protocols for sending your emails: insecure SMTP, SMTP over TLS, or SMTP over SSL. Optionally, configure your account to require the use of SSL or TLS.
Opportunistic TLS delivery to TLS capable mail servers
LuxSci automatically uses TLS to deliver email securely to any recipient email server that supports SMTP TLS.
Dynamic TLS negotiation & fallback; MTA-STS
Encrypted message delivery to any recipient
Secure High Volume allows you to send secure, encrypted, messages to every recipient, no matter what email provider the recipient uses.
Recipient restrictions
Use allow and deny lists to control to whom or to what domains messages can be sent. Send copies of all outbound email messages to an email address of your choice.
Email capturing
Direct copies of all sent messages to another email address of your choice.
Email content monitoring/DLP
Scan all outbound email for specific content (keywords, phrases, or regular expressions). Matching messages can be denied, sent to an auditor, or auto-encrypted using SecureLine^TM.

Feature
Private Labeling Available
Private labeling is an additional service offered to high volume customers. Private labeling enables your customer to see only references to your company, not LuxSci, on your user interface and sent emails.
Branded Email Headers [Optional]
Dedicated server customers can choose to have the headers of all outbound messages "branded" with their domain name and organization and with all references to LuxSci and "High Volume" removed: Hostname: the server hostname that appears in the mail headers will be your server name (e.g.. "`rs999.yourdomain.com`" instead of ours (e.g. "`rs999.luxhv.com`") Reverse DNS: Anyone looking up the hostname of your server from its IP address will get your custom hostname back, and not a LuxSci server name. Abuse Email: Include your own "Abuse Reporting" email address in the headers instead of ours (though the emails will still be routed to us). Powered by: Include your own "Powered by" header line in place of our "LuxSci High Volume" header line.
Account-wide monthly recipient limit
For each account, choose the monthly recipient limit. A recipient is one email sent to one person.
Sending limits are soft: Your sending won't be cut off.
If you exceed your sending limit, you will still be permitted to send. However, you will be assessed a fee to pay for the excess sending at the beginning of the next month. LuxSci does have the option to make your sending limits "hard," so that you are stopped when your limit is reached and no fee will be assessed. Contact LuxSci support if you would like to change your limit type.
Configure optional per-user sending limits
Allocate your resources effectively by establishing user-specific recipient and/or bandwidth limits.
Usage notices sent automatically at customizeable thresholds
Track your SMTP usage with reports that are automatically sent to the sender or account administrator when usage reaches a specified limit.
Receive & check inbound email
Get a fully-functional email hosting account with SecureLine^TM, IMAP, POP, and WebMail access to your inbound email. This is very useful if you need to process replies and bounces, or need to managed secure replies to encrypted outbound email messages.

Dedicated, Zero-Trust Aligned Email Solutions

Unlike other high volume emailing solutions that use shared clouds for email sending, LuxSci is unique in that it provides each client with their own dedicated server, cluster, or unique custom deployment. This has two advantages: higher security and more flexibility.

First, by isolating email servers from other customers, it adds another level of security. LuxSci has long supported the Zero Trust security model which advises keeping trust zones small to protect sensitive data. At LuxSci, this means we use micro-segmentation and dedicated network firewalls to isolate each customer's server configuration. By using a dedicated server cluster that is segmented from other customers, data is kept isolated and secure.

In addition, using a dedicated server cluster allows customers to create custom configurations that can be designed to meet any email volume or throughout need. Using a dedicated solution means never having to share server resources with other customers and allows for more control over sending rates and IP reputation. Customers can also request high availability and disaster recovery options to keep systems online in the unlikely event of a data center failure. These high availability options include:

High-availability network firewalls
High-availability network load balancers
High-availability, high-capacity outbound email sending servers
High-availability web/application servers
High-availability replicated MySQL clusters
High-availability storage
System isolation and capacity scaling
Dedicated network segments
DDOS Protection
An additional disaster recovery footprint in a distant geographic location

FAQ: What to Know About Secure High Volume Sending

How many subscribers, lists, or campaigns can I have?

As many as you like. LuxSci does not limit the number of legitimate subscribers or how you segment your lists. We base our plans only on sending volume-the number of recipients you send messages to each month.

What is a "recipient"?

A recipient is an email address a message is sent to. It's also the unit we use to measure your email sending. One message to one person is one recipient, two messages to the same 10 people comprise 20 recipients, 1000 messages sent to one person each equals 1000 recipients.

How many messages can I send at once?

LuxSci does not limit the number of messages you can send at once. You can send a single message or send email blasts that go to thousands or millions of recipients. Your plan determines the maximum number of recipients you can send to per month and your throughput requirements dictate the kind of infrastructure that LuxSci will provision for you. See also: How fast can I send email?.

What if I go over my monthly sending limit?

If you reach your email sending limit, you will still be permitted to send email. However, you will be charged an excess usage fee at the beginning of the next month. If you consistently exceed your sending limits, it will be more cost-effective to upgrade your plan to a higher monthly sending limit.

If you would prefer to suspend sending when you hit your limit (and avoid excess usage fees), please contact LuxSci support.

You can review your monthly sending limit, what happens if you hit your limit, and what the excess usage fee is in your account's High Volume Sending Overview Page.

Does LuxSci provide email sending or campaign management software?

Yes, LuxSci's Secure Marketing solution is a web-based HIPAA-compliant email marketing and campaign management tool. You may also be able to integrate your current email software with Secure High Volume.

Can I use TLS for compliance and skip messages that can't go TLS?

Yes. LuxSci SecureLine^TM can be configured with a feature called TLS Exclusive. When you enable this, LuxSci will dynamically use Forced TLS to deliver your messages securely to everyone who can support TLS and will drop messages to those who don't (with appropriate notes in our delivery tracking system). If you have low priority messages (e.g., email marketing messages) which still need to be secure, "TLS Exclusive" high volume sending is a perfect fit.

How many concurrent SMTP connections can I make at once?

The number of sustained concurrent SMTP connections you can make at once depends on the type of and number of dedicated servers that you have. For small/standard plans, sustained concurrent connections should be 1-4 and bursting should be 20 or less.

Do LuxSci servers get blacklisted?

While any email provider can get blocked on occasion, LuxSci takes stringent measures to keep this from happening. LuxSci has very strict acceptable use policies and manually checks every new customer to keep spammers out. LuxSci's monitoring system works to detect any improper use before it becomes a problem. As a result of our due diligence, problems are rare. If a problem does occur, LuxSci's staff have the training to resolve the issue ASAP. Also, when you use a dedicated server (and a dedicated IP address), your IP address reputation reflects only your own sending history.

Do I have to change my email service to LuxSci?

No, you do not need to change your email hosting service to LuxSci. You can easily configure your sending programs to send emails through LuxSci's email sending service without affecting your existing email solution.

Does LuxSci provide pre-warmed IP addresses?

LuxSci sends your email through dedicated servers that have dedicated IP addresses. Your dedicated servers may or may not use IP addresses recently used by other customers. So, they may or may not be "pre-warmed." We recommend warming up your new server for best delivery results. See also: Warming up your IP address automatically.

Do you guarantee inbox delivery?

While neither LuxSci nor anyone else can ensure that every message is delivered to every inbox, our excellent reputation and stringent security measures maximize the chances that your email messages will be delivered to the intended recipients. LuxSci will advise you on how to construct your messages and maintain your lists and campaigns for the best results. See Key Ingredients for Good Deliverability.

Can I track my email delivery and bounces?

Yes. LuxSci provides reports of messages sent, delivery status, as well as complaints of spam such as feedback loop complaints.
