Below is another example of how using a custom DNS with your email service provider can help increase trust and deliverability. In this example, TechTarget sent me an email to sign up for their Online ROI Summit. However when clicking on the link my email client warns me that the link could be fraud. Why? Because the link resolves through the email service providers domain instead of TechTarget. This is why custom DNS coupled with a unique IP is the gold standard for deliverability and trust.
