Shared and Dedicated IPs: Which Should You Choose?

Determining whether to use a shared or dedicated IP address for email delivery depends largely on your email sending volume and the level of control you desire over your sending reputation. Shared IPs are similar to a virtual mailing address where your sending reputation is influenced by other users sharing the IP, making it suitable for those sending fewer than 100,000 emails annually. Conversely, dedicated IPs offer full control over reputation as they are used exclusively by a single domain, which is ideal for high-volume senders exceeding 100,000 emails per year. Twilio SendGrid provides options for both, with dedicated IPs available through their Pro 100K plan, which includes features like email validation and subuser management. The choice between shared and dedicated IPs should be guided by the sender's consistency and volume, with dedicated IPs providing greater control and potentially better deliverability for larger email programs.
