Do ESPs block spam traps automatically?

Myth: False. ESPs cannot automatically detect and block all **spam traps**. Traps look like normal email addresses. No system reliably identifies them without insider information.

ESPs may use validation services that catch some known problematic addresses. But **spam traps** are designed to be undetectable by senders.

Prevent trap hits through proper acquisition (never buy lists), confirmed opt in, and good hygiene. Do not rely on **ESP** detection of traps.
