The Ultimate Guide to Email IP Reputation: Shared vs. Dedicated IP for Netcore

Published : August 30, 2023

In the world of email, having an impeccable IP reputation isn’t just beneficial—it’s essential. Much like how an individual’s past actions shape their reputation, the historical behavior of your sending IP becomes the gauge by which inbox providers judge your trustworthiness.

It’s the reason why choosing between a dedicated IP and a shared IP is paramount for email senders. But which setup aligns best with your business needs? In this guide, we’ll unpack the differences between these setups and shed light on their impact on your email delivery.

Distinguishing dedicated IP from shared IP

The primary difference between a dedicated and shared IP revolves around who utilizes the IP for email dispatches:

Dedicated IP address

It’s exclusively yours. Every email you dispatch gets channeled through this unique IP, which means you possess full autonomy over its reputation.

Shared IP address

This is communal. The reputation amalgamates the email activities of all users, generally grouped by volume or business type.

Now, at a first glance, it might seem that the dedicated IP is the superior choice. But the email ecosystem isn’t quite that straightforward. Several variables including cost, email types, sending frequency, expertise level, and readiness to send can influence the choice.

Delving deep into dedicated IP addresses

When you possess a dedicated IP, your sender reputation is untouched by other businesses. This shields you from the reckless behaviors of other senders but also means you won’t gain from the good reputations they might have earned.

Here’s a deeper insight:

1. Sole control over reputation

Your reputation remains unsullied from other businesses. It’s your actions alone that determine whether you are seen as trustworthy.

2. Ideal for high-volume senders

A consistent and high email volume is necessary to build a solid IP reputation. At Netcore, we suggest a minimum of 1M messages monthly to effectively sustain a dedicated IP. For businesses dispatching lower volumes or doing so sporadically, achieving this might be challenging.

3. IP warm-up is essential

Starting from scratch? Then, you’ll have to patiently and systematically increase your sending volume, referred to as “warming up” the IP. This process, essential for new IPs, often requires incremental sending increases over weeks or even months.

4. Greater costs and maintenance

Dedicated IPs generally come at a premium. Apart from the cost, they demand ongoing maintenance to ensure optimal performance.

5. Mistakes can be costly

Slip-ups on a dedicated IP can have severe repercussions. A minor misstep could potentially tarnish your reputation, making recovery an arduous process.

Insights on shared IP addresses

Shared IPs amalgamate the reputations of all users, which can be both an advantage and a disadvantage.

Here’s the lowdown:

1. Collective impact on reputation

Sharing an IP can either buoy or sink your reputation. It’s pivotal to associate with an email provider like Netcore, which meticulously vets its users to ensure everyone adheres to best practices.

2. Sending volume flexibility

The collective volume on a shared IP diminishes the significance of individual sending patterns.

3. Fast email warmup

There’s a short warm-up period required, enabling you to scale your email campaigns faster.

4. Cost-effective

Shared IPs offer a more economical solution. The costs get distributed among all users, making it wallet-friendly.

5. Easier recovery from blunders

On a shared IP, occasional mistakes are absorbed and diluted by the sheer volume of emails being sent, offering a safety net of sorts.

Why dedicated IPs aren’t the magic elixir for deliverability

Contrary to popular belief, dedicated IPs aren’t a guaranteed solution to deliverability issues. In fact, without proper management, they might exacerbate problems.

With the shift to IPv6 due to the exhaustion of IPv4 addresses, many ISPs now place greater emphasis on domain reputation. This evolving dynamic suggests that IP reputation might gradually become less important, diminishing the primary advantage of dedicated IPs.

Netcore’s approach

At Netcore, we don’t just sell dedicated IPs as a panacea for all deliverability woes. Our core focus is on meticulously curating and preserving an impeccable reputation for our shared IPs. We have stringent vetting processes in place, ensuring only legitimate senders utilize our platform. By choosing Netcore, you’re aligning yourself with an elite group of senders.

However, for businesses with specific requirements—like dispatching over 1M emails monthly or having intricate sending needs—we do offer dedicated IPs. Always with the understanding that they’re used wisely and judiciously.

And there you have it! A detailed, thorough exploration of shared versus dedicated IPs, tailored specifically for Netcore’s offerings. With this knowledge, you’re well-equipped to make the best decision for your business’s email sending needs.
