Securely Host Your Images with Sailthru
Sailthru-hosted images now support SSL, with HTTPS URLs produced from the Image Library, by default.
Now, when you bring media assets from your Image Library into a message, Sailthru automatically produces an HTTPS URL for each. You and your customers can rest easy knowing that no matter what email client they use, images in their Sailthru-powered emails will be served to them securely.
HTTP URLs for the same images will continue to work, so your older messages will not be affected.
