After analysis: 7 simple tricks for newsletters that really work

How good are your newsletters? At the beginning of the summer, we invited a number of students from our “Design Camp” to analyze ten newsletters from different clients operating in different industries, ranging from fashion to technology and experiences. The results are clear: small, smart improvements can make a big difference to opens, clicks and sales.

Here we share the most common mistakes – and our top tips on how to fix them!

1. put a headline that captures immediately

Common mistake: Many letters had only the company name as the heading or a too generic heading.

Do this: Spend time on a headline that arouses curiosity and reflects the content. Think: concrete, emotional or promising.

Rule Tips: Change headlines and test variations easily in our drag & drop editor. Use our AI feature in the editor for more inspiration and variation on headlines.

2. Keep the design together

Common mistake: Crisp fonts, too many colors, and mixed image styles make the newsletter cluttered.

Do this: Use a maximum of 2 fonts and a uniform color palette. Let the images speak the same language and use whitespace.

Rule Tip: Create your own templates and save your brand assets in Rules Brand Style feature to keep a consistent style that matches your brand.

3. Show your expertise

Common miss: Texts were often ‘too generic’, with a tone that felt AI-generated. Many newsletters lacked concrete details or unique insights.

Do this: Dare to geek out! Highlight what only you know – material choices, behind the scenes or specialist tips.

Rule Tips: Put in personalized blocks with tips or expert quotes from someone knowledgeable to build trust.

4. Lifting the CTA

Common mistake: Important buttons were far down or disappeared in the flow.

Do this: Place your main call to action (CTA) high up. Repeat further down for long letters.

Rule Tip: A/B test your mailings with our updated A/B test feature and try placing buttons in different places to see what has the best effect.

5. Choose the right images

Common miss: Generic images that tell nothing about the content. Students suggested more people and context!

Do this: Choose images that evoke emotions and show the product in use. Think: “What does the picture help the reader to understand?”

Rule Tip: Use the image library in Rule and sort into image folders to keep a consistent look.

6. Keep it short and sweet

Common mistake: Long introductions and unnecessary fluff lose the reader’s interest.

Do this: Write for the skim reader. Use short paragraphs, clear subheadings and bullet points.

Rule Tips: Split the text into blocks and test different versions with our updated A/B testing feature.

7. always go mobile!

Common mistake: Images and buttons looked good on desktop but worked worse on mobile.

Do this: Think mobile first! Short texts, large click-through areas and clear CTAs.

Rule Tip: Always see a live preview of the mobile version directly in our editor.
