The Benefits of Dedicated IP Addresses vs. Shared

Thursday, December 22nd, 2022

Choosing a dedicated or shared IP address may seem like an inconsequential decision, but it can significantly impact the effectiveness of your patient engagement efforts. Learn why dedicated IP addresses are preferred for transactional and marketing emails in the healthcare industry.

What is a Dedicated IP Address?

An IP address is a string of unique characters that can be found in the headers of your sent emails. Internet service providers use them to identify the origin of the email message. ISPs use the IP address’s reputation to determine if the message is spam and should be delivered to the recipient.

Dedicated IP addresses belong to your organization and cannot be used by other customers of your email service provider. By having a dedicated IP address, the server’s reputation and delivery power are a function only of the organization’s sent mail. Dedicated IP addresses have several advantages, including:

  • No shared resources with other senders
  • Reputation management and brand safety
  • Improved email deliverability
  • Easier to troubleshoot blacklisting issues

We will discuss the benefits of dedicated IP addresses and what they mean for your organization later.

What is a Shared IP Address?

In contrast, a shared IP address does not belong to your organization and is shared among the customers of an email service provider. Shared IPs are the default option for many email service providers. Upgrading to a dedicated IP usually incurs an additional fee, so many organizations get started using a shared IP address. It is a cost-effective solution for some smaller organizations with limited or small sending needs. No IP warm-up is required since the address is active and in use, meaning it’s easy to start sending quickly. However, as organizations grow and their sending needs increase, they may be frustrated with the following:

  • Slow email delivery
  • Undelivered emails
  • Emails frequently flagged as spam
  • Blacklisted IP addresses

When email becomes a critical business channel, it’s often time to switch from a shared IP to a dedicated solution.

The Benefits of Dedicated IP Addresses for Patient Engagement Emails

Healthcare organizations that rely on email should strongly consider using dedicated IP addresses to improve trust and ensure critical communications are sent on time and are received in patients’ inboxes. If patients cannot receive critical information about appointments, prescriptions, or other healthcare needs, it will negatively impact their experience and may cause them to choose another provider.

No shared resources with other senders

When sending substantial quantities of time-sensitive emails, your sending speed may be limited by others using a shared IP address. Important emails (like password resets and appointment reminders) can get stuck in long sending queues, and you will have no control over when the messages are sent out. In contrast, you have complete control over your sending speed and resources when using a dedicated IP address (or multiple IP addresses). External users will never slow you down.

Reputation management and brand safety

Another perk of using a dedicated IP address is that you can match it to your company’s DNS records. To do this, your mail server’s IP address to send outbound emails must have a “Reverse DNS.” This is the responsibility of the email service provider (at LuxSci, we set this up automatically). If set up incorrectly or missing, you will have significant deliverability issues.

When someone performs a reverse DNS lookup on a company’s dedicated IP address, it will clearly identify the sender and provides additional information about the company. This data builds trust and improves your reputation with ISPs.

Improved email deliverability

The main reason many choose dedicated IP addresses is to improve the deliverability of their emails. If email service providers do a terrible job vetting their customers and allow spammers to use their service, bad actors can quickly contaminate reliable IP addresses. When using dedicated IP addresses, you can control the IP warm-up process and prevent employees from engaging in spammy practices. By having full control over your IP reputation, you can improve the deliverability of your emails and prevent them from being flagged as spam.

Easier to troubleshoot blacklisting issues

Though most ISPs will not acknowledge “whitelists,” senders using dedicated IP addresses can subscribe to Complaint Feedback Loop (CFL) programs to help minimize complaint rates. If you participate, ISPs will forward complaints from users about emails sent from your organization’s IP addresses.

Even if you can’t get on a whitelist, understanding when and why your IP address is blacklisted is valuable information. When using a shared IP, it’s impossible to know why it was blacklisted. Another user could have sent spammy content, used a paid list, or sent a large mailing to an old contact list. To get off the blacklist, troubleshooting the issue, fixing it, and avoiding future mistakes are essential to increasing reputation and staying out of the spam filter. It’s easier to identify which emails are generating spam complaints when you aren’t sharing IP addresses.

Conclusion

Consider using dedicated IP addresses if your organization uses email for patient engagement efforts. They provide the reliability and reputational benefits you need to execute these campaigns at scale. Contact us today to learn more about how to engage patients with personalized email campaigns.

Infrastructure Requirements for Marketing and Transactional Email

Tuesday, June 14th, 2022

To design an appropriate email infrastructure, organizations must understand the types of emails they plan to send. Outside of regular business communications between colleagues, marketing and transactional emails are used to communicate externally with clients and customers. Although they are often lumped together, transactional and marketing emails serve different purposes and require different hardware configurations to successfully send emails with good deliverability.

What are Marketing Emails?

Marketing emails primarily contain content intended for a commercial purpose, like advertisements, promotions, or other marketing messages. Marketing emails are sent to groups of contacts that are prospects or customers to influence them to make a purchase or take a commercial action.

Some examples of marketing emails include:

  • Customer newsletters
  • Promotional offers
  • Event invitations
  • Other types of sales communications

One significant difference between marketing and transactional emails is that recipients must explicitly opt-in to receive marketing emails. It is against CAN-SPAM rules to send unsolicited marketing emails to people who have not consented to receive them. The penalties for non-compliance can be quite severe. Always allow individuals to opt out of marketing emails to stay compliant.

What are Transactional Emails?

Transactional emails are messages that relate to previous interactions or commercial relationships with a company. Users trigger email sending by taking specific actions, and the emails contain only information that is critical and relevant to the recipient.

Examples of transactional emails include:

  • Transaction receipts
  • Order updates and shipping notifications
  • Password resets and security notifications
  • Appointment reminders
  • Review requests

Transactional emails facilitate an already agreed-upon transaction or update a customer about an ongoing transaction. Transactional messages are exempt from most provisions of the CAN-SPAM Act, and recipients do not have to opt in to receive emails. For example, when someone orders a pair of sneakers online, the company does not need permission to email them when the order ships out.

How do I know if an email is a transactional or marketing message?

The email content determines whether a message is transactional or marketing. Some emails can contain both messages. We recommend asking three questions to ensure compliance with the CAN-SPAM Act:

  1. What is the primary purpose of the message?
  2. Whom is the message sent to?
  3. Is the content misleading or deceptive?

First, what is the primary reason for sending the message? If the purpose is to remind a client of their upcoming appointment, that should be evident. Organizations can include a marketing message (perhaps offering them a coupon to use on additional services at their appointment). Still, the subject line and main message should emphasize the upcoming appointment.

Secondly, is there an existing relationship between the organization and the recipient? Did the recipient willingly join a mailing list? Or purchase a product from the company? The answer, in combination with the purpose of the email, will identify what type of mailing this is.

Finally, do not try and launder marketing messages as transactional emails. Sending an email with a misleading subject line like “Your Order Status” containing little to no information about a recent order is not permitted by CAN-SPAM.

Infrastructure Requirements

Most organizations need to send both types of email. The email sending requirements for sending bulk marketing emails differ from transactional emails. Marketing emails are one message sent in bulk to a large list of recipients. For example, a list of previous customers is sent an email promotion announcing a sale on sandals. Sending one email to thousands of recipients at the same time requires different memory and CPU than messages sent on a one-to-one basis. It typically does not matter if the sandal promotion reaches the recipient’s inbox at 10:00 am or 10:15 am. The message contents are not seriously time-sensitive. In the case of a marketing email, sending volume is more important than sending speed.

On the contrary, transactional emails are sent on a one-to-one basis and can be highly time-sensitive. Emails like password resets and order confirmations must arrive in the recipient’s inbox immediately after submission. This requires a different server configuration from marketing emails because speed is more important than sending volume. Designing different server configurations for marketing and transactional email is highly recommended to achieve sending goals.

At LuxSci, we design custom server configurations to meet the volume and throughput requirements for organizations of any size.

HIPAA Requirements

Both marketing and transactional emails could fall under HIPAA regulations. Any communications that imply a relationship between a healthcare provider and a patient should be encrypted and follow HIPAA requirements. LuxSci provides both a Secure Email Marketing platform and Secure High Volume Email services to support the emailing requirements for HIPAA covered entities and their associates.

LuxSci’s Secure High Volume bulk emailing service provides excellent deliverability for HIPAA-compliant mass mailings, including newsletters, appointment reminders, and other types of transactional emails. Using email server clusters is an effective way to send high volumes of email in a scalable manner.

It is often the case that customers require either:

  • Sending to large numbers of recipients (millions to tens of millions or more in a month)
  • Sending many messages quickly (in short bursts)

In either case, the mail server needs to handle large numbers of concurrent connections and process large mail queues quickly.

How to Determine Your Email Throughput Needs

Tuesday, November 2nd, 2021

When designing an email infrastructure to send high volumes of email, you need to determine your email throughput needs. Throughput refers to how much data can be transferred within a specific time frame. It is a practical measure that is influenced by many factors including server power, network speeds, concurrent connections and more. This article will explain some of the factors that you can control to help you design an email sending infrastructure that fits your business needs.
