Master Email Deliverability: Keep Your Cold Outreach Out of Spam 📬
Everybody talks about finding triggers, identifying prospects, and crafting the perfect emails. But something that's rarely discussed enough is how to set up a strong email infrastructure.

Hey there!
Let's talk about something that can make or break your sales outreach: email deliverability. You can have the perfect prospects and killer copy, but if your emails land in spam... game over!
Why This Matters So Much
Email deliverability accounts for roughly 15% of your outreach success (I made up this number) - which doesn't sound huge until you realize it's the difference between reaching your prospect or talking to an empty void.
Think about it: What's the conversion rate on emails that are never seen? Exactly. Zero.
Seriously, the number of sales teams I see with amazing strategies but terrible deliverability would blow your mind!
The Email Infrastructure Playbook
Here's how to set up your cold email infrastructure like a pro:
Domain Strategy
🚫 Never use your main company domain for cold outreach
✔ Purchase separate domains that are similar to your main one
✔ Redirect these domains to your main website (keeps it legitimate)
✔ Mix it up: Get some Google Workspace mailboxes and some Outlook mailboxes (3 per domain)
Technical Configuration
✔ Properly set up DKIM, SPF, and DMARC records (non-negotiable!)
✔ Use Spintax technique to create variations of your text (avoiding identical messages)
🚫 Avoid words like "free", "now", "risk-free" on your emails (check your copy with spam word checkers if necessary)
🚫 Skip links in initial emails - yes, even your website in the signature
🚫 Disable open rate tracking (those invisible pixels can trigger spam filters)
The Warming Process
Start with 2-3 weeks of pure warmup (5-20 emails/day)
Begin cold outreach gradually (20-30 emails/day/mailbox)
Continue warming alongside cold emails (25-33% of daily volume)
Remember: This isn't a race. Build reputation steadily!
Tools That Make This Easy
Domain & Mailbox Setup:
Domain providers: Spaceship, CheapNames
Mailboxes: Google Workspace, Microsoft Outlook
Email Infrastructure:
