### Design for Phones First

Most subscribers will scan quickly, so the email must be readable on a small screen.

An email can look polished on a laptop and still feel broken on a phone. Long buttons wrap, images 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 the email like a subscriber would see it. A clean mobile version is usually a good sign that the desktop version will be fine too.

- Keep images useful and compressed. An image should explain, support, or show something real.
- Use buttons for important actions and make the text short enough to fit.
- Keep enough space between sections so the email is easy to scan.
- Avoid putting 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.
