The Problem
Newsletter lists collect dead addresses, typos and spam traps over time. Sending to them raises bounce rates and complaints, which mailbox providers use to route more of your mail to spam.

Frequently asked questions
How often should I clean my newsletter list?
Verify before major sends and at least quarterly. If you mail an older or re-engagement segment, verify it first because those addresses decay the fastest.
Does cleaning help with spam traps?
Verification removes invalid and many risky addresses that correlate with traps. Combined with good list hygiene, it reduces the chance of hitting traps that hurt your reputation.
