Image file requirements

Many signature designs include images, logos and banners. The following requirements should be considered when adding images to your signatures:

We recommend the use of PNG, JPG and JPEG images.

NOTE: SVGs are not supported within Exclaimer. This is due to the limitations of a number of email clients and devices.

The maximum file size allowed for uploaded images is 150kb.

The maximum dimensions for an image are 2048 pixels by 2048 pixels.

We recommend that any email signature images you use are 96 dots per inch (dpi).
