How do deletions without opens affect sender score?

Deleting without opening is a soft negative signal. It suggests the recipient recognized your sender name or subject line and decided the message was not worth their time.

Occasional deletions are normal. People get busy. But consistent patterns of recipients deleting your mail without ever opening it tells providers that your messages are not valued by your audience.

This signal is weaker than explicit spam complaints but contributes to the overall engagement picture. Providers aggregate all signals, and a pattern of non-engagement pulls your reputation down gradually.

Unopened deletions are like merchants who see your ship arrive and turn away without inspecting the cargo. They know what you typically bring, and they are not interested. The harbor master notices that pattern.
