What email marketers say9Marketer opinions

Email marketer from Quora explains that it can make sense to use a shared IP address when first starting out, as they may not have enough traffic yet to get a dedicated IP address. You can still build your email reputation while you warm up the IP and your domain and then move onto a dedicated IP when needed.

Email marketer from Validity shares their opinion on dedicated vs shared IPs, and it's mostly dependent on the company and the mailing strategy. If you are just starting or send emails irregularly, using shared IP addresses is the best choice. If you don't follow email best practices, you will suffer the consequences on either shared or dedicated IP addresses.

However, they caution that deliverability can be impacted by the sending practices of other users on the same IP pool.
Email marketer from Salesforce StackExchange responds that sharing a pooled IP is a good starting point, especially for new businesses or departments with low email volume.

However, it is crucial to monitor deliverability and be prepared to move to a dedicated IP once the volume increases.

Email marketer from SendGrid shares tips on how to warm an IP address. Using a shared IP address can help avoid this all together, but has some risks if other senders aren't following best practices.
What the experts say5Expert opinions
Expert from Spam Resource explains that if other senders on the IP address are having deliverability issues, it can effect your deliverability. They explain that if you're using a reputable shared IP address this shouldn't be an issue.
Expert from Email Geeks explains that the policy was designed to prevent shared IP pools from becoming 'hot garbage' by preventing low quality mail from being sent on them.

They suspect that this system ceased after they left.
Expert from Email Geeks shares that shared IPs at SFMC can have issues due to the low reputation of other clients. They recommend sharing the existing dedicated IP instead of using the general SFMC shared pool. They suggest that sending more than 2.5 million emails a day is possible, depending on campaign speed. They also propose using two dedicated IPs shared between divisions as a safer alternative.
Expert from Email Geeks explains that you still need to warm up the domain on a shared IP, questioning the initial reason for considering it. They mention a client sending 20M/day per IP, suggesting adding the new division to the dedicated IP is viable. They also recommend considering a second dedicated IP for redundancy.
