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.
