Gmail Finally Said What We've Been Saying for Years

Google didn't raise the bar. They just put up a sign that says "minimum height to ride." These requirements? We've been telling senders to do this stuff for a decade. SPF, DKIM, DMARC, easy unsubscribe, keeping spam complaints under 0.3%. This isn't new. What's new is that now there are consequences.

Yahoo rolled out almost identical rules at the same time. That was the real signal. When two of the biggest mailbox providers coordinate enforcement at once, the days of winging it are officially over. If you send more than 5,000 messages a day to Gmail or Yahoo users, you either comply or your mail stops arriving.

The one-click unsubscribe requirement is the one catching people off guard. It's not enough to have an unsubscribe link buried in 8pt font at the bottom. You need a proper List-Unsubscribe header with a working one-click option. Most ESPs handle this, but if you're sending through your own infrastructure, check.

The biggest mistake people are making right now: rushing to set DMARC to p=reject without understanding alignment. That breaks things. Start with p=none, read your reports, fix your sending sources, then move to quarantine, then reject. There's no shortcut, and there's no deadline that justifies skipping the work.
