A prospect has replied, but I can't find the answer in my inbox

First, check your spam and trash folders.

If it's not there, the reply may have come from someone else. When a prospect forwards your email to a colleague and the colleague replies, Qualifier counts it as a reply from the prospect, but the email in your inbox is from the colleague. Search your inbox for the company name or its domain (for example "@company.com") to find it.
