How do you get listed?

Common listing triggers include: sending to spam traps (indicates list quality problems), high complaint rates, association with spam campaigns, compromised infrastructure sending unauthorized email, and network policy violations (sending from dynamic IPs).

Spam trap hits are particularly damaging. Pristine traps (never-valid addresses) suggest purchased lists. Recycled traps (abandoned addresses) indicate missing list hygiene. Both trigger investigations and potential listing.

Indirect causes: sharing IP pools with bad senders, using link shorteners associated with spam, and hosting content that spammers reference. You can be listed for association rather than direct spam sending. Due diligence on infrastructure and content sources matters.
