The rules of the inbox have changed, and so has the definition of “deliverability.” In the post-Gmail-update era, you’re no longer competing just for attention; you’re fighting to even get seen.
Why the Game Has Changed
Google’s recent updates have made inbox filters smarter, stricter, and far less forgiving.
Even if you’re not a spammer, your emails can still get caught in the crossfire.
Here’s the problem:
- Higher authentication standards
- Tighter thresholds for spam complaint rates
- Increased scrutiny of sender behaviour
This means outreach systems that worked six months ago could be sabotaging you today.
The Core Pillars of an Anti-Spam Stack
To stay visible (and credible), your outreach setup needs to be more than just “send and hope.”
1️. Authentication First
SPF, DKIM, and DMARC aren’t optional anymore. Without them, you’re waving a red flag at filters.
2️. Domain Reputation Management
New sending domains should be warmed gradually, not thrown into 500-email-a-day blasts.
Monitor sender scores like you monitor open rates.
3️. List Quality Controls
Dead contacts, spam traps, and irrelevant titles aren’t just bad for conversion; they actively damage deliverability. Verified lists aren’t a luxury.

4️. Reply Detection & Sequence Pausing
Continuing to send after someone replies doesn’t just look sloppy; it triggers spam algorithms faster.
5️. Engagement-Based Sending
Your system should track which prospects open, click, and respond, and adapt send patterns accordingly.
Why “More Emails” Isn’t the Answer
In the new ruleset, volume without precision is a one-way ticket to the Promotions tab, or worse, spam.
The outreach systems winning right now are:
- Sending fewer, better-targeted emails
- Using intelligent sending schedules
- Prioritising conversations over campaigns
Filters reward consistent, relevant, low-complaint activity, and punish spray-and-pray.
The Human Layer That Filters Can’t Fake
Automation is powerful for scaling, but it’s the human signals in your outreach that cut through.
- Context-aware follow-ups
- Subject lines that sound like they’re from a person, not a newsletter
- Tone that matches the recipient’s industry and role
Think of your automation like a self-driving car: it’s incredible for cruising on the highway, but you still need a driver in city traffic.
