What email marketers say11Marketer opinions
Email marketer from Email Geeks shares that if you have your domain hooked up to google postmaster tools you should be able to see the IP reputations for your shared ips. If they are high then there is no reason so to believe you will get better delivery. If they are low or bad then it might be in your interest to start developing your own. Growing dedicated IPs is whole other operation with a lot of know how and patience involved. Rob is also a big proponent of shared and dedicated environments to hedge your bets. One bad sender can ruin the fun for everyone and one or two mistakes can tank a dedicated.

What the experts say4Expert opinions
Expert from Word to the Wise shares that while a dedicated IP provides the opportunity to establish a strong sending reputation independent of other senders, it doesn't automatically guarantee improved deliverability. The actual improvement depends entirely on the sender's practices and their ability to maintain a positive reputation.
Expert from Spam Resource explains that a dedicated IP can help improve your email deliverability because you have complete control over the IP's reputation, but this also means you are solely responsible for maintaining a good sender reputation. It’s a double-edged sword.
Expert from Email Geeks explains that if you’re not seeing “mail from IP blocked” then moving to a dedicated IP won’t change anything.
Expert from Email Geeks shares to consider risk mitigation. Take your average email revenue per day. What's a day of blocking at 40% of that going to cost you? That's your shared IP risk, that's what you're hedging against.
