Warming Up Your IP Addresses Automatically

Thursday, June 21st, 2018

When sending email messages, there are many best practices for ensuring optimal deliverability.   I.e., for getting your messages into your recipients’ Inboxes and for staying off black lists.  One very important factor in deliverability is “IP reputation.

Good reputation: If your server is known to send lots of good quality email (email that people do not consider spam-like), then your server’s address (its “IP Address”) is looked on favorably by ISPs (such as Yahoo!, Google, Microsoft, etc.) and you can send large quantities of good email and have it all delivered.  Your server has a good reputation and your server’s IP address is “warm” (think warmed up and humming a long).

Warming up an IP address

Bad reputation: If your server is a known source of junk or malicious email (according to the recipients of the email — it doesn’t matter what you think about the email quality), then you will have a hard time getting your email delivered and many ISPs will throttle your email, accepting only a few messages a time.  Your server has a poor reputation and work will need to be done to repair it.

No reputation: If you just got a new server, it may not have been sending any email for a while.  Or, if you have a server but it has been idle for a long time (e.g, months).  In either case, your server’s address may have “no reputation.”  ISPs are very skeptical about email from servers with no reputation or recent history of good email sending.  A typical sign of a spammer is when a server with little or no reputation suddenly starts sending large quantities of email.  ISPs will detect this and they tend to quickly throttle or block such servers…. moving them from “no reputation” towards “bad reputation”.

Case Study: Halloween Express Chooses LuxSci for Large Scale Seasonal Email Marketing

Monday, January 26th, 2015


Halloween Express
 is one of the most aggressive and dynamic Halloween chains in the United States. Started in 1990, Halloween Express has both company owned and franchised locations throughout the U.S. Their success is based on offering the largest selection of Halloween merchandise available anywhere.

Halloween Express chose LuxSci in 2014 for their massive seasonal email marketing needs.  LuxSci resolved the issues that they experienced with previous providers, saved them money, and enabled an extremely successful online campaign involving millions of email messages sent in a short period of time.

Halloween Express was very pleased that they could quickly scale up sending for the Halloween season, and then back off to a lower level for the rest of the year, without compromising their sending reputation.  They are so satisfied with their experience, that they are staying on for 2015 and are moving their business email services for their hundreds of employees over to LuxSci as well.

This is the story of Halloween Express’ timely switch to LuxSci’s dedicated High Volume SMTP Relaying service.

Maximizing Delivery Speed and Reliability for Large Scale Email Marketing

Monday, September 8th, 2014

You need to send millions of messages to your large opt-in mailing list over the upcoming holiday season.  You need these messages to go out pretty quickly and to not get blocked by your recipient ISPs so that the maximum number of your (potential) customers get your marketing messages and thus you can maximize your conversion rates on these messages.

This is a common scenario that we see, often from customers who have been using another provider that is excessively expensive, where delivery is sluggish, and/or where their messages are getting blacklisted or grey listed by their recipient’s systems.

Here we will share with you our standard prescription for solving this delivery dilemma once and for all.  There are multiple important factors involved, each of which will contribute to your success.

Why LuxSci’s Business Email Servers are Not on Blacklists

Monday, January 20th, 2014

LuxSci is serious about the quick and efficient delivery of all email sent by our clients. We take extra steps to ensure that our servers sending outbound email are not blacklisted.  Indeed, while it is impossible to never get on any blacklist (unless you are not sending email), our business and enterprise email hosting servers have very rarely been blocked; in theses cases, we have quickly re-routed email around the blocks to ensure delivery until the block is removed.

(Note that this article applies to our email hosting services, and not to our separate High Volume outbound email marketing service — which we run through separate servers and which we also monitor constantly to catch and remediate any possible blacklistsing).

Transactional/Bulk email with ePHI in It? What to do about HIPAA

Thursday, August 29th, 2013

Case in pointA medical lab that needs/wants to send test results to patients via email.  This is:

  • Bulk email … possibly 100s or 1000s of messages/day
  • Transactional … every message is important and unique.
  • ePHI … every message contains private health information governed by HIPAA

Customers that have approached us looking for solutions for scenarios like this and others (e.g. medical news, appointment updates and reminders, etc.) have had problems managing this kind of electronic messaging because:

  1. Their own ISPs put limits on the maximum number of messages they can send in a day
  2. Most email marketing solutions and bulk mailing solutions do not have a HIPAA bulk email compliance component and thus are completely useless for sending ePHI of any kind.
  3. All messages must be encrypted in a HIPAA compliant way, making in house solutions difficult, especially when combined with #1.
