About Outlook
Which Outlook you’re seeing
“Outlook” is several different email clients. This preview shows Outlook.com on the web, the free inbox at outlook.com that also handles hotmail.com and live.com addresses. It doesn’t show Outlook for Windows or Mac, or the Outlook phone app, and those can render the same email differently.
What to look for in the screenshots
- Images that don’t load, or load at the wrong size.
- Text that wraps or spaces differently than in your editor.
- Buttons and columns out of line, especially at phone width.
- Whether Gmail clipped the same email, shown in the Gmail screenshots.
Before you preview
Run the HTML through Preflight’s email check first. It catches links that won’t work and Gmail’s clip without using your one preview of the day.
In Letterhead, the weight check runs while you write.
The composer weighs every issue and shows what’s making it heavy, so you can trim before Gmail clips it.
| The old way | In Letterhead |
|---|---|
| Learn that Gmail clipped you from a reader’s reply. | The composer weighs every issue and shows what’s making it heavy, before you send. |
| Trim the HTML by hand to get under the limit. | Letterhead strips redundant styling from what it sends, so it goes out lighter than you wrote it. |

Why does my email look different in Outlook?
Each Outlook version renders HTML its own way, and some ignore CSS that other inboxes support. Check the versions your readers use.
