When choosing between shared and dedicated IP addresses in Amazon SES, it’s important to consider your email sending habits, volume, and how you manage your sender reputation. If your email patterns are irregular and your volume varies, shared IP addresses may be the best choice. On the other hand, dedicated IP addresses give you more control over your email reputation. Standard dedicated IPs are isolated from other senders, so your reputation won’t be affected by others. If you’re having trouble with deliverability using shared IPs, switching to dedicated IPs can help give you more control and isolation.
