You know the feeling.
You send a campaign, expect the usual handful of replies… and nothing. Not even a polite “thanks but no thanks”.

It’s not your messaging. It’s not the market. It’s Google tightening the taps again.

How Google’s New Rules Hit Recruiters

Google’s latest update is the clearest sign yet that inbox providers have had enough. For years, recruitment email has been “high volume, low engagement”, and Gmail now treats that as a red flag. The new rules aren’t new ideas. They’re stricter policing of things many agencies have ignored for too long. Authentication, alignment, spam rates, unsubscribe hygiene, and domain behaviour.

And from November 2025 onward, enforcement gets aggressive. We’re talking temporary failures, rate limits, and permanent rejections for anything that doesn’t cut it. Google has openly said they’ll keep tightening this, and other providers will be sure to follow.

If you’ve been through a deliverability programme with us, great. You’ve been ready for this for two years.
If you haven’t? Now’s the time.


1. Google’s Core Requirements (Plain English)

Authentication must pass SPF, DKIM and DMARC

If these fail, Google will block or rate-limit your email (codes like 4.7.27, 4.7.30, 4.7.31) .
Think of them as your passport visa stamps. No stamps, no entry.

Your “From” domain must match your authenticated domain

Google will no longer tolerate CRMs using a “nice-looking” From: address that doesn’t align with the domain actually sending the email (4.7.32) .

TLS is mandatory

No encrypted connection = automatic block (5.7.29).
To be honest, noone should have to worry about this. TLS has been standard for any meaningful system for years.

Your spam rate must stay under 0.3% — ideally under 0.1%

User complaints now trigger real consequences. Over 0.3% means you’re not even eligible for mitigation until you clean up for seven straight days .

Three spam clicks per thousand recipients could now tank your domain.

One-click unsubscribe for marketing is compulsory

Google requires RFC 8058 List-Unsubscribe headers in all promotional messages. Footer links don’t count. Mailto doesn’t count. Landing pages don’t count .

PTR (reverse DNS) must be correct or blocked

This mainly affects CRMs with inconsistent infrastructure or anyone self-hosting email (5.7.25) .


2. Why Recruitment Should Care

Recruitment lives in high-sending, low-engagement territory.
You’re sending:

  • Job alerts
  • Nurture emails
  • BD outreach
  • newsletters
  • internal CRM automations

Gmail looks at all that and asks:
Do real humans actually want this?

If the answer is “occasionally”, your risk is higher than ever.

Google’s message is simple:
Behave like a valued publisher, not a spammy opportunist.


3. What You Should Do Next

a) Fix your authentication and alignment

Make sure SPF, DKIM, DMARC and From: alignment are passing.

b) Implement real one-click unsubscribe

List-Unsubscribe headers only. No shortcuts.

c) Segment your lists

Stop hitting every contact with every mailer.

d) Stop mixing message types

Job alerts, newsletters and operational emails need different reputational buffers.

e) Keep spam rate under 0.1%

If you start creeping above it, fix content or stop sending.


4. Ready for the next wave

Google’s update is phase one. Yahoo is aligned. Microsoft and Apple will follow.
By 2026, every major inbox will enforce similar rules.

Agencies who get ahead now will glide through it. Agencies who don’t… won’t.
