An image in your email signature may become blurred or pixelated when sent, even though it still looks sharp during composition.
The problem is caused by the way Outlook manages your image depending to its resolution, which is measured in dpi.
Outlook resizes the image as if it were a 96-dpi image. When sending, Outlook converts and compresses (re-renders) images to 96 dpi with the new dimensions.
Boost My Mail doesn’t modify your images and therefore doesn’t change their quality.
Boost My Mail doesn’t modify your images. The image will be displayed in your signature with the same quality and resolution as the file you uploaded to Boost My Mail.
If you notice that the quality of an image has deteriorated after sending an email via Outlook, it’s because of Outlook’s limitations rather than any defect in Boost My Mail. Outlook scales images to 96 dpi after sending an email, so if your uploaded images don’t meet this requirement, your email’s recipient may end up with a blurred image.
Generate an image with 96-dpi resolution
The quickest and easiest way around this problem is to generate your images with 96 dpi resolution.
Here's how to do it with Photoshop:
- Go to the "Image size" menu
- Enter a 96-dpi resolution
- Tick "Resampling" and "Keep details", and then "Noise reduction" at 100%.
