Most sales reps think cold email is broken. "Nobody reads cold emails anymore," they say.
"Email is dead."
They're wrong.
What's broken isn't the channel — it's the approach. Apollo.io analyzed thousands of cold emails sent to CEOs, founders, VPs of sales, and other executives to understand why some emails get forwarded to procurement teams while others get deleted in three seconds.
The difference isn't luck. It's science.
In this analysis of cold outreach to executives, only 8% of emails generated meaningful responses. But here's what's interesting: Those 8% followed specific, repeatable patterns that anyone can master.
The other 92% failed because they violated one or more of the six fundamental laws discovered.
Before diving into what works, you need to understand how executives actually consume email.
The 3-Second Scan Rule
Executives spend an average of three seconds deciding whether to read, forward, or delete an email. Your subject line and first sentence determine everything.
The Mobile Reality
73% of executive email opens happen on mobile devices, usually between meetings. Your email needs to deliver value in a thumb-scroll.
The Pattern Recognition Filter
Executives have developed sophisticated mental filters for sales emails. They can spot generic templates from the first word. Personalization isn't optional — it's survival.
The Data: The average subject line length in high-performing emails is 7.4 words or 49 characters.

The Company Research Stack
Before writing any cold email, spend three minutes gathering the following.
The Role-Specific Angle
Tailor your approach based on their title.
The Timing Intelligence
Send messages when executives actually read email:
The Spray-and-Pray Approach
Sending the same generic template to 500 prospects. Executives can spot mass emails instantly.
The Feature Dump
Listing product capabilities instead of business outcomes. No executive cares about your 47 features.
The Aggressive Follow-Up
Sending daily follow-ups or using guilt or pressure tactics. This burns bridges permanently.
The Attachment Overload
Including PDFs, case studies, or presentations in the first email. This screams "sales pitch."
Avoid using vague subjects like "Quick question" or "Following up." These get deleted unopened.
Primary Metrics
Secondary Metrics
Cold email is rarely about the first touch. Here's the proven follow-up cadence.
Touch 1: Initial Value
Send your cold email (one of the templates above).
Touch 2: Additional Value (3 days later)
Share a relevant resource, case study, or industry insight.
Touch 3: Different Angle (1 week later)
Try a different value proposition or approach.
Touch 4: Soft Breakup (1 week later)
Give them an easy out while keeping the door open.
Touch 5: Long-Term Nurture (3 months later)
Re-engage with a new trigger event or insight.
The cold email isn't dead — the bad cold email is dead.
The executives in this analysis who responded weren't responding to luck. They were responding to emails that proved the sender understood their world, offered genuine value, and made it easy to say yes to a conversation.
Use these templates, follow the six laws, and watch your reply rates climb from the 92% who get ignored to the 8% who get responses.
