Is Cold Email Dead After Google’s Latest Update? Here’s the Real Truth

Google has dropped another update, and for most senders out there the deliverability has dropped by more or less 50%. And of course, this raises one simple question…

Is cold email dead?
Is the whole cold email and lead gen industry going to die down because of this Google deliverability issue?

To answer this properly, we first have to identify the main issue — what exactly did Google change, and what are the best practices we need to apply right now to tackle it?

Let’s break it down.

What Exactly Did Google Change This Time?

Right now, the situation we’re looking at is this:

Emails sent from Google to Google
Emails sent from Outlook to Google
Emails from SMTP providers, sending tools, and warmup tools to Google

Deliverability dropped by 50% across the board.

Previously, if I sent 1,000 emails, I used to get maybe 10 positives.
Right now, sending the same 1,000, we’re seeing like 4–5 positives.

And yes, this happens almost every year:

Once around June–July
Again around November–December

Why November–December?
Because of the promotional season. Google raises its guard to block spammy messages — all those “50% OFF,” “Free offer,” “Limited time,” “Last chance today,” type of emails.

But here’s the interesting part — even legitimate businesses using fully set-up Google Admin panels get hit, not just new domains.

So no, this isn’t targeted at cold email alone — it’s Google tightening security for everyone.

So Is Cold Email Dead? Not Even Close. You Just Need to Adapt.

Google basically raised restrictions. They do this every year.

Cold email isn’t dead, but the senders who don’t fix their infrastructure will die out.

There are 5 major areas you must lock in right now:

DNS, SPF, DKIM, and DMARC
Domain age (30–60 days minimum)
Stop using open tracking & custom tracking links
Reduce email fingerprinting (use heavy word-level spintax)
Avoid spammy, promo-heavy copy and hidden HTML

Let’s break these down.

1. Fix SPF, DKIM, DMARC (Mandatory, Not Optional)

This is the foundation.
If your authentication records are not set up properly, nothing else matters.

You’re doing cold email to land in the primary inbox.
If your emails land in spam, your offer doesn’t matter — nobody sees it.

Double-check:

SPF
DKIM
DMARC
MX
Routing

If you’re using a vendor or sending platform, verify that they configured everything correctly.

2. Give Your Domains Time to Age

We’re seeing Google evaluate domain age more seriously.

Recommended:

Use domains aged 30–60+ days
Do NOT use fresh domains for cold outreach
Warm gradually, avoid blasting too early

You can buy aged domains from many platforms.
They might not be perfectly branded, but the real goal here is deliverability, not how pretty the domain looks.

3. Stop Tracking Opens, Clicks, and Custom Links

Tracking pixels and link trackers are huge red flags right now.

Google doesn’t like:

open tracking,
custom tracking links,
redirects,
encoded URLs.

Remove all tracking if you want maximum deliverability.

4. Reduce Your Email Fingerprint Using Word-Level Spintax

This is one of the biggest changes you need to implement.

Most people only spintax lines.
You need to spintax words, not just sentences.

Your cold email must be:

Short (50–70 words)
Plain text only
Heavily spintaxed
No links
No images
No bold, italic, colors, HTML

In tools like SmartLead, Instantly, or Email Bison, always use the Remove Rich Text option to avoid hidden HTML — especially if you copied something from Notion, Google Docs, or ChatGPT.

5. Monitor Mailbox Health & Sending Limits

For example in SmartLead, you’ll see:

Green = healthy
Yellow = caution
Red = stop sending

If your mailbox health drops below 95%, reduce sending immediately.

Example:

If you normally send 10 emails per mailbox per day, drop it to 5 until the health recovers.

Also — build a sending buffer.

If you need to send 2,000 emails/day, build capacity for:

3,000–3,500 emails/day (1.5x buffer)

This is critical if you’re running client campaigns.
You don’t want disputes or angry clients because you ran out of sending capacity.

This Issue Will Likely Settle in 2–8 Weeks

These seasonal deliverability dips typically resolve within 2–8 weeks.

During this period:

Don’t panic
Don’t shut everything down
Don’t overreact
Educate your clients
Maintain backups
Reduce volume slightly

Cold email isn’t dying — it’s adjusting.

6. Validate Your Lead Lists Properly

You should validate your lists:

twice minimum
three times if possible
using different validation providers

Yes, it costs extra credits.
But it prevents hard bounces — which protects your domain health.

Also…

Targeting matters.

If your copy isn’t relevant to the lead, they will mark you as spam.

That ruins your domain reputation faster than anything else.

Final Thoughts: Cold Email Isn’t Dead — But Bad Practices Are

Google didn’t kill cold email.

Google killed:

sloppy setups
weak domain authentication
spammy language
identical emails
bad list targeting
overaggressive tracking

If you follow the best practices above, you’ll stay ahead of the curve and continue landing in the primary inbox even during seasonal updates.

Bonus: Want to Use FluentCRM for Cold Email? Read This First.

I personally love FluentCRM inside WordPress.
But FluentCRM isn’t built for cold emailing out of the box.

So to avoid any deliverability issues when sending cold email through FluentCRM, I wrote a plugin addon called FluentColdMail — which expands the functionalities of this awesome plugin and makes it cold-email-ready.

This is actually the first WordPress Cold Email plugin ever built accordingly to our research. You will not need any additional SMTP plugin, everything is built in within this plugin. Just make sure to use the above mentioned recommandations for your cold email marketing campaign.

Here’s what it does:

✔ Multiple inbox support (multiple domains + multiple SMTPs)

You can connect several inboxes from different domains and different SMTP providers.

✔ Set sending limits for each inbox separately

For example:
If you set a limit of 30 emails/day for one inbox and the limit is reached, that inbox stops sending automatically for 24 hours.

✔ Automatic sending distribution based on total capacity

If you have 10 inboxes with a limit of 30 emails/day each:

10 inboxes × 30 emails = 300 emails/day

Once the 300 emails are delivered, sending stops — protecting your deliverability.

✔ Auto-resume after 24 hours (+ manual resume button)

If your list has 450 contacts and only 300 were emailed today, the system:

automatically resumes after 24 hours, or
you can click the manual “Resume Sending” button.

✔ Everything is logged neatly

You get a clean, organized dashboard with:

sending logs
inbox status
delivery stats
pause/resume actions

✔ And yes — the plugin is 100% FREE.
