How to Write Marketing Emails:
Copywriting Formulas That Get Opened & Clicked
Transform boring newsletters into compelling, conversation-starting emails. Master direct-response frameworks, irresistible subject lines, conversational formatting, and high-click CTAs.
The Mission: Eradicating Corporate Jargon in Favor of Genuine Human Connection
We teach conversational email copywriting because people do not build emotional relationships with faceless corporations. When a small business writes like a stiff corporate entity, subscribers tune out. But when you write like a trusted friend sharing a valuable lesson over coffee, your emails get read from top to bottom. Persuasion is not about manipulation—it is about clarity, empathy, and making the next step completely obvious.
Subject Lines & Preview Text: Getting the Open
Balancing Curiosity, Self-Interest, and Mobile TruncationYour subject line is the gatekeeper. Over 50% of emails are opened on mobile devices where subject lines truncate at approximately 38 to 45 characters. The three most dependable subject line frameworks include:
“The 1 DNS record 80% miss...”
Piques curiosity while pointing to a concrete technical mistake.
“Are lead magnets dead?”
Challenges common industry assumptions to prompt immediate debate.
“[Checklist] Fix deliverability today”
Bracketed tags inform the recipient of an immediate, tangible asset.
The 3 Proven Copywriting Formulas: PAS, AIDA & BAB
Never Stare at a Blank Screen Again1. PAS: Problem → Agitate → Solution
Problem: “Tired of spending 10 hours a week sending manual quote follow-ups?”
Agitate: “Every hour you spend typing repetitive emails is an hour taken away from serving high-paying clients—and half your leads fall through the cracks.”
Solution: “Here is our 3-step automated workflow blueprint that recovers 20% of lost proposals on autopilot.”
2. BAB: Before → After → Bridge
Before: “You have an email list of 500 contacts, but whenever you send a newsletter, you hear crickets.”
After: “Imagine sending an email and receiving 12 qualified consultation inquiries by noon tomorrow.”
Bridge: “The bridge is this single-offer educational framework we deployed with our clients last month.”

Formatting Body Copy for 6th-Grade Readability
Why Whitespace and Short Sentences ConvertPeople do not read emails word-for-word; they scan in an F-shaped visual pattern. To ensure effortless reading on a 5-inch smartphone screen:
- Keep paragraphs strictly between 1 and 3 sentences.
- Use bolding on key takeaways to guide scanners.
- Write in an active voice with simple vocabulary.
- Avoid walls of dense text that induce cognitive fatigue.
Crafting High-Converting CTAs and the Power of the P.S.
The Two Most Read Elements in Direct Response EmailEvery email must adhere to the “Rule of One”: one core idea, one primary action. Never ask a reader to read a blog post, follow you on Instagram, buy a product, and fill out a survey all in the same email.
Additionally, eye-tracking heatmaps consistently show that the P.S. (Postscript) is the second most scrutinized element after the subject line. Use your P.S. to summarize the primary benefit, restate the deadline, or share an objection-crushing client testimonial.
The Science: Data Behind Email Readability
According to linguistic and conversion analytics published by Litmus and Boomerang analyzing over 40 million sales emails:
