For sending 50,000 emails, the consensus is that using a dedicated IP address is generally recommended for better control over sender reputation and deliverability. While one IP address can handle this volume, it's crucial to have a good sender reputation. Excessive IPs (e.g., 500) are considered snowshoe spam. If using a new IP, a gradual warm-up over weeks is essential, starting with small batches and increasing volume. Building and maintaining a positive IP reputation, monitoring volume and engagement, and adhering to authentication best practices are also key.

Regardless of the choice, warming up the IP address gradually is crucial for establishing a positive sender reputation and improving email deliverability. Maintaining a healthy IP reputation and considering the risks of shared IPs are also key.
