Designing Emails That Convert

An email has seconds to earn attention. Good design helps the reader understand the message quickly and act on it.

One email, one goal

Decide the main action you want readers to take. Every element should support it. Multiple competing calls to action reduce clicks.

Design for mobile first

Most emails are opened on phones. Use a single-column layout, large tap-friendly buttons, readable font sizes and short paragraphs.

Create a clear hierarchy

• A strong headline that states the benefit.
• Supporting text that explains briefly.
• A visual that reinforces the message.
• A prominent call-to-action button.

Use images wisely

Images help, but some email clients block them by default. Never put essential information only in images, always add alt text and keep file sizes small.

Plain text versus designed emails

Plain-text emails feel personal and work well for one-to-one style messages, such as founder updates or sales follow-ups. Designed emails suit newsletters, product showcases and promotions. Test both with your audience.

Accessibility matters

Use sufficient colour contrast, logical reading order, descriptive link text and real text rather than text inside images.

Brand consistency

Use the brand's colours, fonts and tone, but keep templates simple enough to load fast and render reliably.

Test before sending

Preview in major email clients, check links and send test emails to colleagues.
