### Design for Phones First

Most subscribers scan emails quickly, so the email must be easy to read on a small screen.

An email can look polished on a laptop and still feel broken on a phone. Long buttons can wrap, images can shrink awkwardly, and large sections can push the important action too far down.

Use the [Email Editor](https://mailrith.com/docs/email-editor.md) preview to check how the email will look to a subscriber. If the mobile version is clean, the desktop version is usually fine too.

- Keep images useful and compressed. Each image should explain, support, or show something real.
- Use buttons for important actions, and keep button text short enough to fit on a phone.
- Keep enough space between sections so the email is easy to scan.
- Do not put important text only inside an image.
- Check the footer and unsubscribe area as carefully as the header.
- Use saved [Email Templates](https://mailrith.com/docs/email-templates.md) for layouts you need often.
