Can I upload my images to Litmus for email testing?
No, at this time Litmus does not provide image hosting for your email tests. The images for your email will need to be hosted on your own server or through your Email Service Provider using absolute links (no relative links). In order to return the most accurate results possible, Litmus looks for images hosted on your servers, rather than hosting the images for you and failing to reveal any issues with hosted images
If your images are hosted within a protected environment, you may need to add Litmus' IP addresses to your whitelist. Please email us and we can provide you our current list of IPs.
