A shared client pool is essential for email sending as it allows us to maintain a collection of IP addresses and resources that multiple clients can use. This approach optimizes resource management, ensures load balancing, and provides a stable service—especially for smaller senders or new customers who lack the email volume to justify their own dedicated IP.
Why Do We Need Shared Client Pools?
1. IP Pool Management
By pooling IP addresses, we can rotate and manage sending IPs effectively.
This prevents overloading any single IP, which could lead to deliverability issues.
Pooling also enables better management of sender reputation by distributing email traffic across different IPs.
2. Pre-Warmed Reputation
If the majority of senders follow good practices, the pool benefits from an established positive reputation.
Smaller senders or new accounts can achieve good deliverability without needing to build their own reputation from scratch.
3. Inconsistent and Low Volumes
Shared IP pools are ideal for clients with low or inconsistent email volumes.
ISPs like Yahoo, Microsoft, and Google deprioritize emails from low-volume or inconsistent IPs, making shared pools a more reliable option.
4. Warm-Up
Shared IPs are already warmed up and actively used, eliminating the need to gradually increase email volume as required for a dedicated IP.
5. Cost-Management
Dedicated IPs come with additional fees, whereas shared IP pools provide better deliverability at a lower cost.
Depending on one or two dedicated IPs increases the risk of deliverability issues, but shared pools distribute traffic across multiple IPs, mitigating that risk.
6. Reputation Management
A shared client pool helps maintain a consistent sender reputation.
We use shared reputation scores for IPs and domains, benefiting all clients by improving overall deliverability.
7. Minimize the Risk
Clients with similar sending patterns can be grouped together, minimizing risks and ensuring consistent deliverability across the shared pool.
Shared client pools are crucial for maintaining reliable email deliverability. They are especially beneficial for small or new senders by providing cost-effective, reputation-enhancing, and risk-reducing email sending solutions compared to dedicated IPs.
