Cold Email Deliverability

Definition

Whether your cold email lands in the inbox or spam folder. Depends on domain reputation, domain setup (SPF, DKIM, DMARC), list quality, and how much people engage with you. No auth setup = spam folder. Bad lists = spam folder. Simple as that.

Why It Matters

Perfect copy hits the spam folder and generates zero pipeline. Deliverability is the table stakes before copywriting even matters. A 40% deliverability rate with great copy beats 100% deliverability with weak copy—but you need both.

How to Improve

• Set up SPF, DKIM, and DMARC on your sending domain. Most people skip this and wonder why they get flagged. Don't be that person.
• Warm up your email sending gradually. Send 10 emails day one, 20 day two, 50 by day five. Let ISPs trust your pattern.
• Remove bounces and unengaged addresses immediately. Old list = spam list.
• Write like a human. Avoid ALL CAPS, excessive links, and terms like 'URGENT' or 'EXCLUSIVE' that spam filters catch.
