Rebuilding your IP reputation

This is a client that was having issues with their IP reputation. They were on a shared IP pool at SendGrid. With my help we cleaned their list, set up dedicated IPs, warmed those IPs and began phasing out the shared IPs. The high reputation IPs are their dedicated IPs that we're migrating to.

Rebuilding your domain reputation

Gmail accounts for 40-80% of most B2C lists. If your emails aren't converting, it can be due to your domain reputation. This is a client that I've been helping with their domain reputation in a difficult vertical for inbox placement. It's not impossible to repair your reputation at Google.
