What It Is
An email that looks great on your desktop can fall apart on mobile, or in a specific email client. Most opens happen on mobile, so design mistakes cost clicks before a single word is even read.
This guide covers everything needed to design emails that render correctly and convert: layout rules for width, columns, and hierarchy, a typography size chart, image optimization rules, and a CTA button design guide.
A mobile rendering checklist is included so you can catch the most common breakage points: oversized images, unreadable font sizes, buttons too small to tap: before you hit send, not after.
Who It's For
- Your emails look fine on desktop but you've never checked how they render on mobile
- You're designing your first templates and want layout and typography rules to follow
- You want a CTA button design reference to improve click-through rate
- You're not sure what image dimensions or file sizes to use for email specifically
Probably not for you if
- You want a custom template actually designed and coded for your brand. See Custom Klaviyo Email Template Design in the Setup category
- You want copy written too, not just design, pair this with the free Email Copywriting Swipe File

A PDF, emailed instantly, covering layout rules, a typography size chart, image optimization rules, a CTA button design guide, and a mobile rendering checklist.
Design principles are platform-agnostic: the layout, typography, and image guidance apply whether you build in Klaviyo, Mailchimp, or a raw HTML editor.
No. It's written as a practical checklist rather than design theory, so you can apply the rules directly in a drag-and-drop email builder without prior design training.
