For a small email database of 2,000 contacts sending only 500 emails per week (approximately 71 emails per day), a dedicated IP address is generally not suitable. This volume is considered very low, making it challenging to maintain a consistent and positive sending reputation for a dedicated IP. Dedicated IPs require a significant and steady volume of email to warm up and maintain reputation with internet service providers (ISPs). Without sufficient volume, the IP's reputation can fluctuate or even degrade, leading to deliverability issues.
Key findings
Low volume threshold: Sending 500 emails per week (roughly 2,000 per month) is significantly below the minimum volume typically recommended for a dedicated IP, which often starts from 50,000 or even 100,000 emails per month.
Reputation maintenance: Insufficient volume on a dedicated IP can hinder your ability to build and maintain a strong sender reputation, increasing the risk of your emails landing in spam folders or being blocklisted. ISPs need consistent sending patterns to trust an IP.
Shared IP suitability: A shared IP address is generally the better choice for low-volume senders, as the reputation is managed collectively by the email service provider (ESP) across a larger pool of users.
Costs and complexity: Dedicated IPs often come with higher costs and require more hands-on management, including a proper IP warming process, which is unnecessary and impractical for very low volumes.
Key considerations
Volume consistency: Consider if your email sending volume is likely to increase significantly and consistently in the near future. If not, a shared IP is more forgiving for fluctuating or low volumes.
IP warming requirements: A dedicated IP needs a structured warm-up period, where email volume is gradually increased. This process itself might take weeks or months, and cannot be sustained with only 500 emails per week.
Reputation responsibility: With a dedicated IP, your reputation is solely your responsibility. For low volumes, the collective reputation of a shared IP often provides better baseline deliverability.
Shared IP benefits: Shared IPs are suitable for small senders because they benefit from the collective sending habits of many users. This can lead to more stable deliverability for low volumes, provided the overall pool has a good reputation.
What email marketers say
Email marketers often discuss the trade-offs between dedicated and shared IPs, especially for smaller sending volumes. The general consensus among marketers is that a dedicated IP requires a substantial and consistent email volume to justify its use and maintain a healthy sender reputation. For very low volumes, such as 500 emails per week, marketers typically advise against a dedicated IP, citing challenges in reputation management and the benefits offered by shared IP pools.
Key opinions
Volume insufficient: Marketers frequently state that 500 emails per week is far too low to effectively warm up and maintain the reputation of a dedicated IP address.
Shared IP preferred: For small databases and low sending frequencies, shared IP addresses are considered the safest and most practical option.
Reputation risk: Attempting to use a dedicated IP with low volume increases the risk of damaging your sender reputation, as ISPs will not have enough data to assess your sending behavior positively.
Misconceptions: Some businesses (especially small ones) mistakenly believe a dedicated IP is always superior, often based on incomplete information or a misunderstanding of how IP reputation works at low volumes.
Key considerations
ISP requirements: Many ESPs (Email Service Providers) have minimum sending volume requirements to even offer a dedicated IP, reflecting the industry understanding that low volumes are not suitable.
Deliverability stability: A shared IP provides more stable deliverability for low-volume senders, as they leverage the good reputation maintained by the ESP across a large sending pool.
Future growth: While a dedicated IP may be beneficial for future high-volume sending, it should only be considered when the business can commit to a significant and sustained increase in email volume.
Focus on content: For small senders, focusing on email content quality, list hygiene, and engagement metrics is far more impactful for deliverability than acquiring a dedicated IP.
Marketer view
Email marketer from Email Geeks suggests the volume is extremely low for a dedicated IP. They emphasize that maintaining IP reputation requires consistent sending volume, which is not feasible at 500 emails per week.

What the experts say
Email deliverability experts consistently advise against dedicated IP addresses for low-volume senders due to the intricate requirements of IP reputation management. They emphasize that maintaining a stable and positive reputation on a dedicated IP necessitates a high and consistent email volume. Without this, the IP's reputation can quickly falter, leading to poor inbox placement. Experts recommend shared IP pools for senders with small databases or infrequent sending schedules, as these environments provide a more stable and managed reputation.
Key opinions
Volume critical: Experts agree that low volume, like 500 emails per week, is insufficient to build and sustain a reliable reputation on a dedicated IP. ISPs need consistent data to establish trust.
Shared IP superiority for low volume: For small email databases and infrequent sends, a shared IP is the recommended choice because the collective reputation of the shared pool provides more stability.
Reputation degradation risk: Without adequate sending volume, a dedicated IP's reputation can quickly degrade or be inconsistent, making it difficult for emails to reach the inbox consistently.
IP warming challenge: The necessary IP warming process is practically impossible with such low volumes, as there isn't enough traffic to gradually introduce the IP to ISPs.
Key considerations
Consistent sending: The primary factor for a dedicated IP's success is a consistent and predictable sending pattern. Low volumes inherently lack this consistency from an ISP's perspective.
Deliverability impact: Poor IP reputation due to low volume can lead to emails being filtered as spam, bounced, or even blocklisted (or blacklisted), negatively impacting overall deliverability.
Cost efficiency: For the volume in question, the additional cost and management overhead of a dedicated IP are simply not justified, offering no deliverability advantage over a shared IP.
Alternative strategies: Small senders should prioritize list hygiene, email authentication (SPF, DKIM, DMARC), and engaging content over a dedicated IP address for improved deliverability.
Expert view
Expert from Email Geeks emphasizes that there is not enough volume to sustain the reputation required for a dedicated IP. They strongly recommend that shared IP addresses are the best route for senders of this size, ensuring better deliverability management.

What the documentation says
Technical documentation from various ESPs and email deliverability resources often outlines clear guidelines for dedicated IP usage, almost universally recommending higher sending volumes. These guidelines are based on the mechanics of how ISPs track and assign reputation to sending IP addresses. They highlight that insufficient volume prevents proper IP warming and consistent reputation building, which are crucial for successful inbox delivery. Shared IPs are presented as the default and often superior option for senders who do not meet these volume thresholds.
Key findings
Volume requirements: Documentation frequently sets minimum sending volumes for dedicated IPs, often in the range of 50,000 to 100,000 emails per month, far exceeding 500 per week.
Reputation building: IP warming is a documented necessity for dedicated IPs, a process that relies on gradually increasing email volume to build trust. Low volumes make this process ineffective.
Shared IP as default: ESPs typically place new and low-volume senders on shared IP pools by default, acknowledging that this provides the best chance for good deliverability without individual IP management burden.
Consistency matters: ISPs value consistent sending patterns for IP reputation. Irregular or very low volume sending makes it harder for automated systems to classify an IP as trustworthy.
Key considerations
Deliverability stability: Documentation suggests that for low volume, the inherent stability of a reputable shared IP pool, where the collective volume smooths out individual sending fluctuations, is superior for deliverability.
Resource allocation: Opting for a dedicated IP when not needed can divert resources (time, money) that could be better spent on improving email content, list quality, or engagement strategies.
Provider policies: Review your ESP's documentation regarding dedicated IP eligibility and requirements. Many providers specify minimum sending volumes to ensure the IP can maintain its reputation.
Reputation risk assessment: Understand that an unmanaged or underutilized dedicated IP poses a greater risk of deliverability issues due to lack of sufficient positive sending data to establish trust.
