Design tips for 600×150
- ✓Always 600 px wide (1200 px for retina) — wider images are not scaled in Outlook.
- ✓Important copy belongs in the HTML text, not in the image: many clients block images at first.
- ✓Keep files small, ideally under 100 KB — email clients load all images at once.

Frequently asked questions
- What is a 600x150 bar for?
- For secondary messages: a shipping offer, a date, a discount code. It interrupts the reading flow less than a full header and can be reused across several sends.
- Should the button be part of the graphic?
- Visually yes, functionally no. Because many clients block images until the reader allows them, the real click target should be an HTML button or a linked text area, otherwise a blocked image leaves a dead end.
- Which file format and file size?
- myfeedr delivers 600×150 as PNG (lossless) and JPG. For trafficking, the JPG is what counts: around 40 KB is a realistic target for this size – small enough for any network without visible quality loss.
