Is 500 emails per week enough volume for a dedicated IP?

For 500 emails per week, a shared IP is highly recommended. Dedicated IPs require much higher, consistent sending volumes (typically tens of thousands to hundreds of thousands monthly) to build and maintain a good reputation with ISPs. With low volume, a dedicated IP can struggle to establish credibility, making deliverability worse.

What is IP warming and why is it important for dedicated IPs?

IP warming is the process of gradually increasing email sending volume from a new IP address to build a positive sender reputation. For a dedicated IP, it's crucial. Without sufficient volume and a slow ramp-up, ISPs may view a new dedicated IP with suspicion, impacting deliverability. This process is not feasible with only 500 emails per week.

What are the pros and cons of using a dedicated IP versus a shared IP for small sending volumes?

While a dedicated IP gives you full control over your reputation, it also means you bear full responsibility for it. If your volume is too low, you risk having an unestablished or poor reputation. A shared IP, on the other hand, benefits from the collective good reputation managed by your email service provider, often leading to better deliverability for low-volume senders.

Are there other factors more important than IP type for small email databases?

Yes, for small email databases, focusing on list hygiene, engaging content, and proper email authentication (SPF, DKIM, DMARC) is far more important. These practices build strong domain reputation, which is often more impactful for deliverability at lower volumes than the IP type itself.

When managing email deliverability, one of the most common questions that comes up is whether to use a dedicated IP address or a shared IP address. For a small email database of 2,000 contacts, sending around 500 emails per week, it might seem appealing to have a dedicated IP for more control. However, this volume is generally too low to effectively build and maintain a positive sender reputation on a dedicated IP.

The role of dedicated IP addresses

The primary purpose of a dedicated IP address is to establish an exclusive sender reputation. Every email you send from a dedicated IP contributes solely to that IP's history and trustworthiness in the eyes of internet service providers (ISPs) like Google and Yahoo. This means if your sending practices are impeccable, your reputation will soar, leading to excellent inbox placement.

However, the flip side is that if your sending volume is too low or inconsistent, the dedicated IP won't have enough data points to build a robust reputation. ISPs rely on consistent sending volume to assess legitimacy. With only 500 emails per week, the traffic is so minimal that it provides insufficient data for ISPs to properly evaluate the IP, potentially leading to emails being flagged for spam or encountering deliverability issues. This low volume essentially makes it harder for the dedicated IP to warm up.

Dedicated IP

You are the sole sender. Your reputation is entirely your own to build and maintain.

Control: Full control over your IP's sending history.
Reputation: Google and other ISPs assign reputation based on your specific sending behavior.
Ideal for: High, consistent sending volumes (e.g., hundreds of thousands per day).

Shared IP

You share the IP address with other senders. Their sending practices can impact your deliverability.

Control: Less direct control over IP reputation, as it's a collective score.
Reputation: Yahoo and other mailbox providers aggregate the reputation of all senders on the IP.
Ideal for: Low or inconsistent sending volumes, where IP warming is difficult.

For your volume of 500 emails per week, a dedicated IP is not suitable. Major email service providers often recommend minimum sending volumes for dedicated IPs because sufficient volume is crucial for reputation building. If you don't send enough mail, your IP's reputation will remain undefined or even appear suspicious to ISPs, making it harder to reach the inbox. It's often better to start with a shared IP address.

Volume and IP warming

IP warming is the process of gradually increasing the volume of emails sent from a new IP address to build a positive sender reputation with ISPs. This is essential for dedicated IPs. You start with a small volume and slowly increase it over days or weeks, allowing ISPs to recognize your sending patterns as legitimate. Without proper warming, ISPs might see a sudden surge in emails from an unknown IP as suspicious, leading to emails going to spam or being blocked outright. For more detail, you can refer to our guide on IP warming for low volume senders.

With only 500 emails per week, it's virtually impossible to effectively warm up a dedicated IP. This volume isn't enough to provide the consistent, growing data ISPs need to trust your IP. A dedicated IP requires a significant and sustained daily sending volume to maintain its reputation. Sending too few emails makes it appear inactive, or worse, like an unknown sender trying to send mail, which can lead to your emails hitting spam folders or even getting your IP placed on a blocklist (or blacklist).

The risks of insufficient volume

Sending too few emails from a dedicated IP can lead to several problems, hindering your deliverability:

Poor reputation: ISPs struggle to assess the IP, leaving it with a low or unknown reputation score.
Spam folders: Emails are more likely to land in recipients' spam folders, reducing engagement.
Blocklisting: An unestablished IP can be more susceptible to being placed on a blocklist or blacklist, even with minor issues.

For context, many providers suggest a much higher volume. For example, some sources indicate that a dedicated IP is only worth considering for senders who expect to send at least 50,000 to 100,000 emails in a single campaign or per month. Other providers, like Zoho Campaigns, state that dedicated IPs are for those sending more than 100,000 emails per month or 50,000 per week. Your 500 emails per week is significantly below these thresholds.

When a dedicated IP is truly beneficial

While a dedicated IP offers complete control over your sender reputation, it also places the full burden of reputation management on you. With a shared IP, you leverage the collective good reputation of other senders on that IP. Reputable email service providers (ESPs) actively monitor and manage their shared IP pools to ensure high deliverability for all users. They enforce strict anti-spam policies and quickly remove any senders who jeopardize the shared reputation. This means your 500 emails per week would benefit from the established trust of a well-maintained shared IP, making it easier to reach the inbox consistently.

The choice between a dedicated and shared IP ultimately comes down to your sending volume, consistency, and your ability to manage IP reputation. For businesses sending transactional emails or marketing campaigns at a low volume like yours, a shared IP is almost always the better choice. It removes the burden of IP warming and reputation management, allowing you to focus on your content and audience engagement.

Generally, a dedicated IP is justified when you consistently send high volumes of email, typically tens of thousands or hundreds of thousands daily. This consistent volume provides ISPs with enough data to build a strong, positive reputation for your IP. It also gives you more granular control over your deliverability, as your sending behavior isn't influenced by others. To learn more about this, you can read about what email volume justifies a dedicated IP.

Volume threshold	IP type
Up to ~50,000 emails/month	Shared IP
50,000 - 250,000+ emails/month	Dedicated IP (with proper warming)
Variable or inconsistent volume	Shared IP (to maintain reputation stability)

Shared IPs are the optimal choice for low volume

A shared IP address is much more appropriate for a small email database of 2,000 contacts sending 500 emails per week. With a shared IP, your email sending reputation is pooled with other senders using the same IP. Reputable email service providers (ESPs) diligently manage these pools, ensuring that the overall reputation remains high. They have stringent policies to prevent bad actors from damaging the shared IP's standing, protecting your deliverability. This means you benefit from a collective, established reputation without the burden of managing a dedicated IP's reputation yourself.

Instead of focusing on a dedicated IP, the small business should prioritize other crucial aspects of email deliverability. This includes maintaining a clean email list by regularly removing inactive or invalid addresses, ensuring high engagement rates through relevant content, and implementing proper email authentication protocols like SPF, DKIM, and DMARC. These factors have a much greater impact on inbox placement for low-volume senders than having a dedicated IP.

For a small sender, focusing on content quality, list hygiene, and consistent engagement is far more impactful than the type of IP address. These foundational practices will ensure that the 500 emails you send each week are well-received and build a positive sender reputation for your domain, regardless of whether you're on a shared or dedicated IP.

Final recommendation

For a small email database of 2,000 contacts sending 500 emails per week, a dedicated IP address is not the most suitable choice. The primary challenge is maintaining a consistent and sufficient volume to build and sustain a strong sender reputation. Without enough traffic, the dedicated IP can struggle to establish credibility with ISPs, potentially leading to poorer deliverability.

Instead, a shared IP address offered by a reputable ESP is much more advantageous for low-volume senders. It allows you to benefit from the collective positive reputation of other senders on the same IP, managed by the provider, removing the complexities of IP warming and individual reputation management. Your emails will inherit a stable and trusted sending environment.

Ultimately, for small businesses, success in email deliverability comes from focusing on audience engagement, list quality, and robust email authentication, rather than investing in a dedicated IP that won't see sufficient volume to perform optimally. These foundational practices will yield far better results for your small-scale email efforts.
