What is a cold email spam checker?

A cold email spam checker analyzes your outbound email copy for words, phrases, and formatting patterns that are known to trigger spam filters. Email providers like Google, Microsoft, and Yahoo use sophisticated algorithms to detect unsolicited commercial email. Certain words and patterns dramatically increase the likelihood of your email landing in spam instead of the primary inbox.

Why does cold email deliverability matter?

If your cold emails land in spam, your outbound program generates zero pipeline. The average cold email reply rate is 1-2%, but that assumes the email actually reaches the inbox. Emails caught by spam filters have a 0% reply rate. Even a few spam trigger words can drop your inbox placement from 90% to under 50%.
