From Spam to Inbox in 48 Hours 📩
I cut cold email spam placement by ~70% in 48 hours across multiple client domains.
…WITHOUT tweaking the copy, sending volume, or inbox warmup settings.
The problem:
Most ESPs can see where a domain is registered. And if it’s commonly abused by spammers or associated with sketchy infrastructure…
So even your “perfect” emails start at a disadvantage.
The fix:
Move your cold email domains to Cloudflare.
Why?
Because it:
• masks your registrar
• adds trusted infrastructure
• makes your setup look more legit to inbox providers
The setup we use 👇
Step 1: Move every cold email domain to Cloudflare.
Cloudflare masks your original registrar and adds enterprise-level security that email providers trust, so you land in the right folder.
Just go to cloudflare.com → create a free account.
Click “Add a domain.”
Paste the domain.
Select the free plan.
It will scan and import your DNS records automatically and give you two new nameservers.
Copy both.
Step 2: Update your nameservers.
Inside your registrar (GoDaddy, etc.):
Go to domain manager → find “nameservers”
Switch from Default → Custom
Paste the two Cloudflare nameservers
Save.
Step 3: Configure DNS records correctly.
Go to Cloudflare → your domain → DNS.
Add/import:
SPF (TXT)
DKIM (TXT / CNAME)
DMARC (TXT)
MX records
Tip: turn OFF the proxy switch in Cloudflare for these.
Step 4: Create a clean, masked redirect.
Go to Cloudflare → Rules → Page Rules
Create a new rule:
Setting: Forwarding URL
Type: 301 (Permanent Redirect)
Destination: https://www.your(main)domain.com/$1
If Cloudflare asks to create an "A record", just accept it.
And that’s it.
What this actually does
• removes hidden trust issues
• improves inbox placement
• reduces spam flags significantly
Most people obsess over:
copy tweaks
subject lines
A/B tests
…but ignore the foundation.
Cold email isn’t just messaging.
It’s infrastructure.
Fix that… and everything else works better.
