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.
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.
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

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.

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

and password authentication. Additional security features can be
implemented as needed.

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

track usage. Premium High Volume users can take advantage of the many email
