Advanced Email List Quality Analytics

Every email list decays. People change jobs, abandon old inboxes, or mistype their address in a form. Over time that natural churn fills your list with invalid addresses, spam-trap domains, and "role" accounts (info@, sales@) that rarely buy from anyone. When you hit Send, those bad addresses bounce or, worse, trigger filtering algorithms that decide you look like a spammer. The result? Lower inbox placement, shrinking open rates, and revenue that quietly leaks away.

Poor list hygiene doesn't just mute today's campaign—it erodes your sender reputation for every future send. Internet Service Providers keep score: exceed a ~2% hard-bounce rate or rack up too many complaints and they throttle or block your domain altogether. That's lost pipeline, wasted ad spend, and frustrated teams asking why their "great email" never reaches real people.

Keeping a list clean used to mean manual exports, one-off verifications, and guess-work exclusions. CommsOK connects straight to your ESP, monitors each send's delivery and engagement signals, and automatically suppresses addresses that show signs of decay—hard bounces, spam-trap patterns, chronic non-openers—so they're excluded from every future campaign. Your team sends as usual; CommsOK quietly handles the cleanup in the background.
