Shared vs Dedicated Email IPs: Full Comparison
Choosing between shared and dedicated email IPs? Here’s the quick breakdown:
- Shared IPs: Multiple users share the same IP. It’s cost-effective, easy to set up, and doesn’t require warming up. However, your email deliverability depends on the behavior of all users on that IP.
- Dedicated IPs: Exclusively yours. Offers full control over reputation and better deliverability for high-volume senders, but it’s more expensive, requires technical expertise, and needs a warm-up period.
Quick Comparison
| Feature | Shared IP | Dedicated IP |
|---|---|---|
| Cost | $2.49–$15/month | $100–$250/month |
| Control | Limited (shared reputation) | Full control |
| Setup | Pre-warmed, ready to use | Requires warm-up |
| Maintenance | Minimal | High (requires monitoring) |
| Email Volume | Low to moderate (<100,000/month) | High (>300,000/month) |
| Deliverability Risk | Affected by others’ behavior | Only impacted by your practices |
Which should you choose?
- Go shared if you’re a small sender or have irregular email needs.
- Go dedicated if you’re a high-volume sender or need strict control over deliverability.
Read on for a deeper dive into how these options impact email reputation, costs, and performance.
Email IP Basics
What Are Email IPs and How Do They Work?
An email IP address acts like a digital return address for your emails. Every email you send carries this unique identifier, which tells the receiving server exactly where the message came from. Think of it as the postal code on a letter - without it, there’s no way to verify its origin.
Most email systems today use IPv4 addresses, which are formatted as four sets of numbers separated by periods (e.g., 192.168.1.1). While IPv6 addresses are becoming more common, their purpose remains the same: identifying and distinguishing devices within a network.
This foundational role of IPs sets the stage for understanding how their reputation affects email deliverability.
IP Reputation and Email Deliverability
Your IP reputation works like a credit score for your email activity. It’s a measure of how trustworthy your IP address appears to email providers, and it directly influences whether your emails land in inboxes or get flagged as spam.
With 14.5 billion emails marked as spam every day - nearly half of all emails sent globally - maintaining a strong IP reputation is essential. A single mistake could derail your email campaigns entirely.
Several factors shape your IP reputation, including sending volume, open and click rates, spam complaints, and bounce rates. Email providers monitor these metrics continuously, adjusting your reputation based on how recipients interact with your emails.
One critical benchmark is the 0.3% spam complaint rate. Staying below this threshold is key to avoiding spam filters and ensuring your emails reach their intended audience.
Authentication protocols like SPF, DKIM, and DMARC also play a crucial role in maintaining trust. These protocols verify that your emails are legitimate and haven’t been tampered with, adding an extra layer of security that email servers rely on when deciding whether to deliver your messages.
"Your server IP reputation directly impacts email deliverability whether you send transactional emails or carefully-planned email marketing campaigns." - Ketevan Bostoganashvili, Technical Content Writer, Mailtrap
The financial implications of poor IP reputation go beyond just blocked emails. With email marketing generating an average return of $36 for every dollar spent, a damaged reputation can significantly impact your bottom line. In essence, protecting your IP reputation is protecting your investment.
IP Warmup in Email Marketing
IP warmup is a crucial step in email marketing, especially when using a new IP address. This process involves gradually increasing the number of emails sent from that IP to build a positive sender reputation with internet service providers (ISPs).
When you start with a new IP, it has no history and is considered "cold". ISPs like Gmail and Yahoo are cautious with unknown IPs. If you send too many emails too quickly, your messages may be blocked entirely.
The warmup process typically lasts two to four weeks and involves a structured schedule to gradually increase your sending volume. For example:
| Warmup Age (Days) | Hourly Email Limit |
|---|---|
| 0 | 20 |
| 7 | 211 |
| 14 | 2,222 |
| 21 | 23,427 |
| 28 | 246,953 |
During this time, focus on sending emails to your most engaged subscribers - those who frequently open and interact with your messages. This helps maximize engagement, which ISPs value when assessing your reputation. Once you've built trust, you can gradually include less active subscribers.
For dedicated IPs, this process is essential because you’re solely responsible for building and maintaining trust. Keep in mind that most reputation systems only retain data for 30 days. If you go more than 30 days without sending emails from a dedicated IP, you’ll need to start the warmup process all over again.
If you’re using shared IPs and sending low volumes of email, warmup isn’t necessary. Shared IPs are managed by email service providers, making them a good option for senders with fewer than 50,000 emails per month.
Proper IP warmup significantly boosts your chances of reaching inboxes. For example, while 57.8% of Google emails land in the inbox, 37.74% end up in the promotions tab. A well-executed warmup can help ensure your emails reach the right place, allowing your campaigns to perform at their best.
Shared IPs: How They Work, Benefits, and Drawbacks
Understanding shared IPs is crucial when considering email deliverability and IP reputation. They operate on a collective model, which comes with its own set of advantages and challenges.
How Shared IPs Work
Think of a shared IP address like an apartment building where multiple tenants share the same address. In this case, several senders use the same IP to send emails, and the overall reputation of the IP is shaped by everyone's combined behavior.
When you send emails through a shared IP, they all carry the same digital signature. Email service providers (ESPs) manage these shared IP pools by grouping senders together and monitoring the overall performance. This setup allows smaller senders to benefit from pooled reputations rather than building one from scratch.
"As evident from the name, a shared IP address gets shared between you and several other senders. It facilitates deliverability by bringing together everyone's IP reputation. And it is easy to set up." - Disha Bhatt, Content Strategist at Email Uplers
This shared setup offers convenience and cost savings, which we'll explore further below.
Benefits of Shared IPs
One of the biggest perks of shared IPs is their affordability. These IPs are typically included in basic ESP plans, with hosting costs ranging from $2.49 to $15 per month. This makes them ideal for businesses with smaller budgets or low email-sending needs.
Another advantage is immediate usability. Shared IPs are pre-warmed and familiar to internet service providers (ISPs), so you can start sending emails right away without the hassle of a warmup process.
Maintenance simplicity is another draw. With shared IPs, the ESP takes care of technical details like monitoring reputation, addressing deliverability issues, and ensuring compliance with industry standards.
Additionally, shared IPs offer reputation cushioning. Minor mistakes, such as a poorly performing email campaign, are diluted by the larger email volume from other senders. This can be especially helpful for new email marketers or businesses experimenting with their strategies.
"Shared IPs are intended for use by small senders that don't send on a regular cadence. The reasoning for this is that the small senders can band together to create a reputation." - Klaviyo Help Center
For instance, a local bookstore sending monthly newsletters or a SaaS startup launching its first email sequences can benefit from the pre-established reputation and ease of use that shared IPs provide.
Problems with Shared IPs
Despite their benefits, shared IPs come with a few drawbacks.
The most significant challenge is that your deliverability is tied to the collective behavior of all senders sharing the IP. If another sender starts spamming or experiences high bounce rates, it could hurt your email performance as well.
"If other senders in the pool experience a sudden drop in performance (blocks, throttling, etc.), it can impact your performance as well." - Ryan Steen, Senior Deliverability Strategist, Klaviyo
Another issue is brand identity dilution. Since your emails are grouped alongside those of other senders, it can be harder to establish a unique sender reputation or build strong relationships with ISPs.
Troubleshooting deliverability issues can also be tricky. When problems arise, it’s often difficult to determine if they stem from your own practices or those of other senders sharing the IP.
Lastly, you’re reliant on your ESP’s management practices. If your provider fails to carefully screen new users or doesn’t effectively monitor the IP pool, the entire group’s reputation could suffer.
While shared IPs offer convenience and cost savings, their shared nature means you’ll need to weigh the risks and consider how they align with your email-sending needs.
Dedicated IPs: How They Work, Benefits, and Drawbacks
Think of shared IPs as living in an apartment building - everyone shares the same space, and one bad tenant can cause problems for the whole building. On the other hand, dedicated IPs are like owning your own home. You have full control, but with that control comes the responsibility of maintaining it, especially when it comes to your email reputation.
What Are Dedicated IPs?
A dedicated IP address is exclusively yours for sending emails. Unlike shared IPs, where multiple senders use the same address, a dedicated IP ensures that your reputation is entirely in your hands. This means your email deliverability is influenced only by your own practices - no one else’s mistakes can drag you down. This setup is particularly useful for businesses that send large volumes of emails or need precise control over their email deliverability. If you’re sending more than 100,000 emails a month, a dedicated IP is highly recommended.
Benefits of Dedicated IPs
Dedicated IPs offer several advantages:
- Full control over sender reputation: Your email reputation is entirely determined by your practices, which can improve inbox placement if you maintain consistent sending habits.
- Better performance insights: With no other senders affecting the data, you get clearer analytics to evaluate your email campaigns.
- Higher email security: Dedicated IPs allow for advanced authentication methods like DKIM and SPF, which are essential for businesses with strict compliance or security requirements.
- Scalability: They’re ideal for handling high email volumes without worrying about the impact of other senders.
For businesses that rely heavily on email communication, this level of control can be a game-changer. But it’s not without its challenges.
Problems with Dedicated IPs
Despite their advantages, dedicated IPs come with some hurdles:
- Higher costs: Dedicated IPs are more expensive than shared options, making them less practical for smaller businesses.
- Technical expertise required: Managing a dedicated IP demands a solid understanding of email best practices and technical know-how.
- Warm-up period: New dedicated IPs require a gradual increase in email volume to build a positive reputation. This warm-up process can take time and effort.
- Reputation risks: Irregular sending patterns, high bounce rates, or spam complaints can harm your IP’s reputation. If the damage is severe, recovery can be difficult, sometimes requiring a complete switch to a new IP.
- Constant maintenance: You’ll need to keep a close eye on key metrics like open rates, bounce rates, and spam complaints. Regular list cleaning and optimizing your sending practices are non-negotiable.
For smaller businesses or those with inconsistent email schedules, the costs and effort may outweigh the benefits of a dedicated IP. It’s a tool best suited for organizations with high email volumes and the resources to manage it effectively.
Shared vs Dedicated IPs: Direct Comparison
Let’s break down the differences between shared and dedicated IPs to help you determine which one suits your email campaigns best.
Comparison Table: Shared vs Dedicated IPs
| Feature | Shared IP | Dedicated IP |
|---|---|---|
| Setup & Warm-up | Simple to start - no warm-up needed | Requires a gradual warm-up and careful setup |
| Cost | Budget-friendly, often included in basic ESP plans | Higher cost, typically $35–$100+ per month |
| Reputation Control | Limited control - other senders impact your reputation | Full control over your IP’s reputation |
| Deliverability Risk | Vulnerable to poor practices of other senders | Lower risk if you follow good sending practices |
| Maintenance | Minimal upkeep required | Requires ongoing monitoring and consistent sending |
| Volume Suitability | Best for low to moderate email volumes | Ideal for high volumes (300,000+ emails monthly) |
| Issue Detection | Hard to pinpoint IP-specific problems | Easier to track and resolve IP-related issues |
| Sending Consistency | No strict need for regular sending schedules | Consistent sending schedules and volumes are essential |
This table highlights the trade-offs between shared and dedicated IPs. Shared IPs are cost-effective and beginner-friendly but lack control, while dedicated IPs offer autonomy and reliability at the expense of higher costs and greater responsibility.
Which Option Fits Your Needs?
Now that you know the differences, think about how each IP type aligns with your email strategy and goals.
Shared IPs are a good fit for businesses sending fewer than 100,000 emails per month or those with irregular sending patterns, such as seasonal retailers or one-off event campaigns. They’re easy to manage, with built-in reputations that reduce setup time and effort.
On the other hand, dedicated IPs are better suited for organizations sending over 300,000 emails monthly. These are especially useful for businesses where email drives significant revenue, like SaaS companies running complex onboarding sequences or e-commerce brands managing advanced automation workflows.
"When email becomes a critical business channel, it's often time to switch from a shared IP to a dedicated solution." - LuxSci
Dedicated IPs also provide added benefits for regulated industries like healthcare or finance. The ability to fully control and monitor your sending reputation makes it easier to meet compliance standards and troubleshoot issues effectively.
If your email volume and resources can support the additional cost and complexity, dedicated IPs can offer greater control and reliability, improving your email performance. However, if your needs are more modest or your sending patterns are inconsistent, shared IPs remain a practical, low-maintenance option.

Managing IP Reputation
Your IP reputation plays a huge role in determining whether your emails land in the inbox or get dumped into the spam folder. The way you manage this reputation depends on whether you're using a shared or dedicated IP, as each comes with its own set of challenges and strategies.
Managing Shared IP Reputation
When you're on a shared IP, you're essentially sharing the reputation pie with other senders using the same address. While you don’t have total control, there are steps you can take to safeguard your part of the equation.
The first step? Choose a reliable ESP (Email Service Provider) that actively monitors and manages its shared IP pool. Top-notch ESPs keep tabs on important metrics like bounce rates, complaints, and engagement levels. They also weed out senders who could harm the group’s reputation by practicing poor email hygiene.
Even though you're sharing the IP, your actions still matter. Stick to high sending standards. Avoid sending emails to outdated or unverified lists, and focus on your most engaged subscribers to keep complaint rates low.
Another critical habit is maintaining a clean email list. Regularly remove inactive or unengaged contacts to ensure you're only reaching people who want to hear from you. Following your ESP's guidelines and adhering to email best practices will go a long way in keeping the shared IP in good standing.
Managing Dedicated IP Reputation
A dedicated IP gives you full control, but that also means you're solely responsible for its reputation. This requires a proactive, hands-on approach.
Start with an IP warm-up process. Gradually increase your email volume to build trust with mailbox providers. Jumping in too fast can damage your reputation before you even get started.
Monitoring is key, whether you’re on a shared or dedicated IP. Use tools like SenderScore.org to check your sender score and services like BarracudaCentral or MxToolbox to monitor blacklist status. For Gmail-specific insights, set up Google Postmaster Tools to track how your emails are performing.
To establish trust, implement SPF, DKIM, and DMARC protocols. These authentication tools verify your emails’ legitimacy, which helps boost your reputation.
Consistency is another must. Maintain steady sending patterns to avoid triggering spam filters. Irregular email volumes or long gaps between campaigns can hurt your IP’s reputation. Aim for a predictable schedule and avoid sudden spikes in activity.
If your reputation takes a hit, act fast. In June 2022, Litmus saw their inbox placement rate drop from 98–99% to below 90%. They pinpointed Gmail as the issue and adjusted by focusing on their most engaged Gmail subscribers. Risky automations, like win-back campaigns, were paused. After contacting Gmail’s postmasters and demonstrating better engagement rates, they slowly returned to normal sending volumes.
Leverage segmentation and personalization to keep your audience engaged. Sending emails that are relevant and valuable encourages positive interactions, which ultimately protects your IP reputation.
Continuous Monitoring Is Key
As Alison Gootee from Braze puts it, reputation is an ongoing reflection of your brand’s respect. Whether you’re on a shared or dedicated IP, keeping an eye on metrics like sender score, blacklist status, spam complaints, bounce rates, and engagement levels is non-negotiable. The main difference between the two lies in how much control you have over improving these metrics.
These strategies lay the groundwork for effective IP reputation management, setting the stage for the next section on Infraforge's email solutions.
Cost Analysis: Shared vs Dedicated IPs
Now that we’ve covered how IP reputation affects deliverability, let’s dive into the financial side of choosing between shared and dedicated IPs. Your decision here doesn’t just impact costs - it also influences ROI and your long-term email strategy. Just like reputation shapes deliverability, cost considerations play a major role in determining the right IP approach.
Shared IP Costs
Shared IPs typically cost between $2.49 and $15 per month and are often bundled into basic Email Service Provider (ESP) plans. This makes them a practical choice for businesses sending fewer than 100,000 emails per month. Because multiple senders share the same infrastructure, the individual cost remains low.
But there’s a catch: hidden costs. If other senders sharing your IP damage its reputation, your deliverability can take a hit. This can lead to lower open rates, fewer clicks, and ultimately, reduced campaign ROI. In essence, while shared IPs are budget-friendly upfront, poor deliverability could cost you more in missed opportunities.
Dedicated IP Costs
Dedicated IPs, on the other hand, cost $100 to $250 per month. For instance, Mailgun and Twilio SendGrid offer dedicated IP options, while Infraforge charges $99 per IP per month (billed quarterly) for cold email outreach.
Although the price is steeper, the benefits are clear. With full control over your IP reputation, you can fine-tune deliverability and boost campaign performance. Dedicated IPs are especially worthwhile for high-volume senders who can maintain consistent email activity. For example, Netcore recommends sending at least 1 million emails monthly to make the most of a dedicated IP. This consistency often leads to better ROI, as emails are more likely to land in inboxes.
Mixed IP Setups
A growing number of email marketers are opting for mixed IP configurations, blending shared and dedicated IPs. Here’s how it works: you use dedicated IPs for high-priority campaigns - like transactional emails, welcome messages, or premium promotions - while routing less critical bulk emails through shared IPs. This strategy allows you to maintain strong deliverability for key campaigns without the full expense of a dedicated-only setup.
Mixed setups also provide a safety net. By reserving dedicated IPs for critical campaigns and using shared IPs as backups, you can ensure consistent delivery even if issues arise. This approach is particularly useful for businesses with seasonal email spikes or those experimenting with new strategies. However, managing a mixed setup often requires advanced monitoring and routing tools, which can add to operational costs. Still, this method strikes a balance between performance and budget, making it a smart choice for flexible email infrastructure planning.

Choosing the Right IP for Your Email Strategy
When it comes to selecting the right IP for your email campaigns, there’s no one-size-fits-all solution. The best choice depends on your business size, email volume, budget, and goals. What works for a small startup may not be suitable for a large enterprise.
Email volume is one of the first things to consider. If you’re sending fewer than 100,000 emails per month, shared IPs are often a better option. They rely on the combined reputation of a managed pool, which can improve deliverability for smaller senders. On the other hand, if your monthly email volume exceeds 300,000, a dedicated IP offers more consistency and control over deliverability.
Budget is another critical factor. Shared IPs are typically affordable, costing just a few dollars per month. Dedicated IPs, however, can cost up to $250 per month, depending on the provider. For small businesses or startups, shared IPs might be the practical choice. But for larger organizations with higher email volumes and stricter control needs, the investment in a dedicated IP often pays off. Providers like Infraforge also offer competitive pricing, making dedicated IPs more accessible.
Control over sender reputation is where dedicated IPs shine. With a dedicated IP, you’re solely responsible for your sending reputation, which is crucial for high-stakes emails like transactional messages or critical campaigns. Shared IPs, by contrast, depend on the practices of other senders in the pool. Fortunately, reputable email service providers (ESPs) typically enforce strict vetting processes to maintain the quality of shared IPs.
If your team lacks technical expertise, shared IPs may be the better choice. They’re managed by your ESP, removing the need for active monitoring and technical oversight. Dedicated IPs, however, require steady sending patterns and regular maintenance, which can be challenging for teams without advanced email infrastructure experience.
Your campaign goals also play a role. Shared IPs work well for testing new strategies or sending occasional newsletters. Meanwhile, dedicated IPs are better suited for businesses where email is a major revenue driver or for campaigns requiring precise segmentation and consistency.
Business size and sending consistency are additional considerations. Smaller teams often benefit from shared IPs, while larger enterprises with higher email volumes typically need dedicated IPs to maintain control and reputation. However, irregular sending patterns can harm a dedicated IP’s performance, as consistent activity is essential for building a positive reputation. If your email schedule varies significantly, shared IPs might provide more stability.
A hybrid approach could be the best of both worlds. By using dedicated IPs for high-priority campaigns and shared IPs for less critical emails, you can strike a balance between control and cost-efficiency. Platforms like Infraforge make it easy to manage such configurations, allowing you to tailor your email strategy to your business needs.
Ultimately, review your current performance metrics when deciding. If your deliverability rates are solid, a shared IP may suffice. But if you’re facing challenges or planning for growth, it might be time to invest in a dedicated IP.
Regardless of your choice, sticking to best practices in your email strategy is essential to achieving long-term success.
FAQs
How do I choose between a shared and dedicated IP for my email strategy?
Choosing between a shared IP and a dedicated IP boils down to your email needs, budget, and how much control you want over your sender reputation.
Shared IPs are a budget-friendly option, especially for businesses sending fewer than 100,000 emails annually. They’re simple to use since they don’t need a warm-up period. However, there’s a catch: your email deliverability can be influenced by other users sharing the same IP. If someone else on the shared IP has poor sending practices, it might affect your emails too.
On the flip side, Dedicated IPs cater to businesses that send high volumes of emails or need consistent deliverability and tighter control over their sender reputation. Unlike shared IPs, they require a gradual warm-up process to establish a positive reputation. But the trade-off is worth it for businesses that value reliability, compliance, and a strong email identity.
For smaller businesses or those just getting started, a shared IP is often the practical choice. Larger businesses or those placing a premium on email performance and control will likely benefit more from a dedicated IP.
What are the pros and cons of using both shared and dedicated IPs for email campaigns?
Using both shared and dedicated IPs for email campaigns offers a mix of benefits and challenges. On the upside, this strategy lets you strike a balance between affordability and maintaining a strong sender reputation. Shared IPs are an economical choice for less critical emails, while dedicated IPs provide greater control over reputation for high-priority campaigns.
That said, there are some potential drawbacks. Shared IPs can pose risks to your deliverability if other users on the same IP engage in poor email practices. On top of that, juggling multiple IPs demands constant monitoring and precise coordination to keep performance steady and avoid disruptions in your email efforts.
What is IP warmup, and why is it important for dedicated email IPs?
IP warmup involves gradually increasing the number of emails sent from a new dedicated IP over several weeks. This process is crucial for establishing a solid sending reputation with Internet Service Providers (ISPs), ensuring your emails land in inboxes instead of being marked as spam.
When you start using a dedicated IP, it has no reputation. Sending a large volume of emails too quickly can trigger blocks or deliverability problems. To avoid this, begin by sending small batches of emails to your most engaged recipients - those who are most likely to open and interact with your messages. Gradually increase the volume over time. This approach signals to ISPs that your emails are legitimate and welcomed by recipients.
The warmup process typically takes 4–8 weeks, depending on your overall sending volume and how engaged your audience is. Taking the time to do this right is key to maintaining strong deliverability rates and building trust with your audience.
