Real-time API vs. bulk list cleaning: which do you need?

Signup forms and list imports have different latency and accuracy trade-offs. A simple framework for choosing.

This is a placeholder article body for the CorrectInbox blog. In production, this page renders content from our CMS — but the layout, typography, and navigation you see here are final.

Why this matters

Email verification only helps if it's honest. Throughout the CorrectInbox product we return a confidence score and admit “unknown” when a catch-all genuinely can't be resolved — rather than inflating results with a guessed “valid.”

That same principle shapes how we write: practical, specific, and free of the deliverability myths that make lists worse, not better.

Put it into practice

The fastest way to understand verification is to run your own list through it. Start free with 100 verifications — no card required.
