You are eligible for dedicated IPs in the following cases:

• There are commercial certifications, such as Validity which require the use of dedicated IPs.
• You have a specific business case, where you request the use of dedicated IPs.
• Your daily send volume is exceptionally high.
• During your onboarding and based on your setup, our team identifies an exceptional requirement for dedicated IPs.

The benefits are the following:

• Improved ownership. You establish and own the IP reputation - your emails won't get grouped with anyone else.
• Easier to maintain. Troubleshooting the root cause of deliverability issues is easier because a dedicated IP address allows you to measure and interpret your own results.
• IP or Commercial Certifications
• IP reputation monitoring, such as SNDS
• Allows your security team to better manage any restrictions on your side.

The benefits of shared IPS are the following:

• Pre-established IPs with existing reputation. These IPs are already established and sending high volume and they already hold a very stable cumulative reputation. 
• Centralized monitoring. We actively monitor all our shared pools against any blocks or issues, and we group similar reputation senders together in order to ensure high performance.
• Shorter or no warm-up phase. You could start sending immediately, with a minimum warm-up period and reach your full audience within days.
• Safer for having irregular sending volume spike. For example: seasonal offers to a larger audience.
