Cold Email Grader

Paste an email. Get a score out of 100, the specific lines that are hurting it, and a rewrite. The score appears immediately, with no signup.

One thing most graders will not tell you: the biggest drivers of whether your email lands are invisible in the text. Authentication, domain reputation, and list quality matter more than any wording choice. This tool scores what it can see and is explicit about the rest.
