After years of working with email deliverability, I built ClearBounce an email verification platform because I kept seeing the same painful pattern over and over.
Here's what most people don't realize about their email lists:
1. Your list is decaying right now
Email addresses go bad at a rate of 2-3% per month. People change jobs, abandon inboxes, and providers shut down accounts. That "verified" list from 6 months ago? A good chunk of it is now dead weight dragging down your reputation.
