Spam Trap

Also known as: Honeypot Address, Trap Address

A spam trap is an email address used by inbox providers to spot bad or careless senders. Hitting one damages your sender reputation and makes it more likely your emails go to spam.

A spam trap is an email address that looks real but is only there to catch bad sending habits. It is run by inbox providers, not by real people. No one signs up for it or reads what you send. It exists to track who is not keeping their list clean.

When you send email to spam traps, inbox providers see you as careless or unsafe. Your reputation drops, and more of your messages get filtered to spam, even for people who want to hear from you. Hit enough traps and you can see opens, clicks, and revenue drop fast. Fixing that reputation can take time and steady, clean sending.

You lower your risk by using clear opt ins, avoiding bought lists, and removing people who never open. Double opt in and regular list cleaning help keep trap addresses out. If performance falls for no clear reason, tighten your list and focus only on active subscribers for a while. That sends a strong signal that you take deliverability seriously.
