A single trap address can burn your reputation. How they appear and how to stay clear.
What they are
Spam traps are addresses used by providers and blocklists to spot senders who don't manage their lists. They never open, click or subscribe: if you mail them, you look suspicious.
The two kinds
- Pristine: purpose-built addresses, never used. Hitting them means you collect addresses badly (scraping, bought lists).
- Recycled: old abandoned addresses turned into traps. They flag stale, uncleaned lists.
How to avoid them
Use double opt-in, never buy lists, remove long-inactive contacts and handle bounces.
No sign-up. Copy the address and send.
