Ever validate your email list and see a bunch of "catch-all" results from big companies? That's often not a bad list — it's a security tool doing its job.

Systems like Proofpoint, Mimecast, and Microsoft Defender block the normal way validators check if a mailbox is real. So a perfectly good address can come back looking unverifiable.

We broke down why this happens and how validation is getting better at telling the difference: https://hubs.li/Q04sSZ6z0

Could signing up for a newsletter get easier? Google is testing a new tool that skips the "check your inbox" step completely.

Instead of clicking a confirmation link, Chrome would confirm you own your email address right on the website. Faster for users. But businesses lose some of what a confirmation email tells them, like whether it was delivered and opened.

Here's what it could mean for you: https://hubs.li/Q04sQdH90
