Basic or Premium?

LuxSci's High Volume Email Sending Service provides two service options, Basic and Premium. Basic is LuxSci's stand alone High Volume SMTP email option. Premium Email Sending services are only available to customers who also have LuxSci's email hosting services. Both options have the same set of capabilities and reporting options that you need to send your emails and to track their status. The Premium High Volume service provides more extensive security options, such as HIPAA Compliance, outbound email encryption, email archival, and additional administrative features and controls.


LuxSci's High Volume Email Service provides a robust set of features to maximize prompt delivery of your emails.

Feature Basic Premium

Use Your Own From Addresses

You can only send messages from an email address in a domain that you own. Addresses from "free email services (e.g., hotmail)" are prohibited.

  • Basic Service users can send from multiple "from addresses" or domains that have been approved by LuxSci Support.
  • Premium Service users can send from any email address in a domain that they own or manage, the approval step is not required.

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 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 Monitoring

LuxSci checks its server IP addresses to make sure that they are not on blacklist databases and to immediately alert us of any blacklisting issues so that they can be immediately addressed.

Graylist and blacklist resolution

LuxSci works to resolve problems that may have resulted in your IP being gray or blacklisted.


LuxSci's reports enable you to detect delivery successes, failures, and SPAM complaints so that you can easily manage your mailing list and resolve unexpected problems.

Feature Basic Premium

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.

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 black 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.

API: Access these reports via our secure API

  • Messages sent
  • Delivery status
  • Feed back loop notices
  • SMTP login failures and message sending rejections

    VERP - Variable Envelope Return Path

    [Optional] Automatic Return Path customization so bounce messages directly indicate the addresses that failed.


    LuxSci provides a base level of sending security by using SMTP username and password authentication. Additional security features can be implemented as needed.

    Feature Basic Premium

    SMTP username & password authentication

    SSL and 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.

    TLS delivery to TLS capable mail servers

    LuxSci automatically uses TLS to deliver email securely to any recipient email server that supports SMTP TLS.

    Encrypted message delivery to any recipient

    Premium High Volume allows you to send secure, encrypted, messages to every recipient, no matter what email provider the recipient uses.

    HIPAA Compliance Option

    Premium High Volume can be used when sending sensitive email messages and ePHI, so that your email sending can be HIPAA-compliant.

    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.

    Outbound Email Encryption

    Send bulk encrypted email to anyone with an email address using SecureLine.

    Email Content Monitoring

    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.

    Message Options

    LuxSci provides the flexibility you need to create and send custom emails.

    Feature Basic Premium

    Up to 200 MB total encoded message size

    A limit of 200 MB in encoded message size allows you to send emails with sizable attachments.

    Up to 1,000 recipients per message

    Choose the number of recipients from a single individual up to 1000.

    Up to 25 Concurrent connections in bursts; 10 sustained

    Up to 25 concurrent connections (per user or IP) lets you send many emails at once; this option is particularly important for transactional emails. Up to 10 sustained connections enables you to send at a consistent rate for a long period of time; this option is extremely useful for sending an email blast to a large subscriber list.

    Any format (HTML, plain-text, multi-part, attachments)

    This option helps ensure that your email can be seen by all recipients, no matter what kind of email viewing program they use.

    Auto-add Taglines/Disclaimers

    Save time by having the software automatically add taglines/disclaimers to your outgoing email in either plain text or HTML format.


    Administrative options allow you to allocate resources effectively and track usage. Premium High Volume users can take advantage of the many email hosting options.

    Feature Basic Premium

    Private Labeling Available

    Private labeling is an additional service offered to high volume customers. Private labelling enables your customer to see only references to your company, not LuxSci, on your user interface and sent emails.

    Account-wide monthly recipient limit

    For each account, choose the monthly recipient limit. A recipient is one email sent to one person.

    Configure optional per-user recipient and/or bandwidth limits

    Allocate your resources effectively by establishing user-specific recipient and/or bandwidth limits.

    Use your own email addresses for authentication

    This option allows you to use a familiar username or a branded username for login.

    Usage notices sent automatically at customizeable

    Track your SMTP usage with reports that are automatically sent to the sender or account administrator when usage reaches a specified limit.

    Easy and instant recipient volume upgrades

    As your email usage expands, LuxSci supports this growth with the upgrades you need.

    • Hostname: the server hostname that appears in the mail headers will be your server name (e.g.. "" instead of ours (e.g. "")
    • 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.
