Email Copywriting That Converts: A Practitioner's Guide

Subject line: get the email opened. That is its only job. It does not need to sell the product.

Preview text: support the subject line. Add context that makes opening feel worthwhile.

First line: keep them reading. If the first line is boring, they close the email regardless of what follows.

Body copy: build enough interest to earn a click. Not a purchase. The landing page handles conversion.

CTA: make the next action obvious. One primary CTA per email. Clear, specific, and impossible to miss.

Short beats long. 4-7 words outperform longer subject lines in our data. "Your order is ready" beats "Great news! Your order from [Brand] is packed and ready to ship!"

Specific beats vague. "3 products under $30" beats "Amazing deals inside." Numbers and specifics signal value.

Lowercase beats title case in most B2C contexts. It feels like a message from a person, not a broadcast.

Questions work for engagement emails. "Still thinking about it?" for abandoned cart. "How is it working out?" for post-purchase.

Avoid: all caps, excessive punctuation (!!!), spam trigger words (free, guaranteed, act now), and misleading subjects that do not match the email content.

Open with the most important information. Not a greeting. Not "Happy Tuesday!" The value prop or the hook.

One idea per email. If you have three things to say, send three emails on different days. Emails with multiple CTAs and topics underperform single-focus emails by 30% in click rate.

Write at an 8th-grade reading level. Not because your audience is not smart. Because inbox reading is fast and distracted. Simple sentences, short paragraphs, clear words.

Use the inverted pyramid: conclusion first, supporting details second, background last. Most readers scan. Put the important stuff where they look.

Button text should describe what happens next. "Shop the collection" is better than "Click here." "Get your results" is better than "Learn more."

One primary CTA. If you have a secondary CTA, make it visually distinct (text link vs button). Two equally prominent buttons split attention and reduce overall clicks.

Place the primary CTA above the fold and repeat it at the bottom of the email. Scanners see the top one. Readers who scroll see the bottom one.

Color: the CTA button should be the highest-contrast element in the email. Test your button color against your brand palette. The "off-brand" color often wins because it stands out.

Starting with "Hi [First Name], we wanted to let you know..." That is a filler opening. Delete it. Start with the value.

Writing walls of text. If a paragraph is longer than 3 lines on mobile, break it up.

Being clever instead of clear. Puns and wordplay are fun for the writer. The reader wants to know what they get.

Burying the CTA. If someone has to scroll past 500 words to find the button, most people leave before they reach it.

Using passive voice. "Your order has been shipped" is weaker than "We shipped your order." Active voice is direct and engaging.
