If I don't subscribe to Premium Image Hosting, can I still include my own images in emails?
Yes. The premium image hosting is just to allow you more diskspace to host your images on Benchmark Email servers. If you have your own website, you can provide the URL for the images in your email OR you can upload your images on any image hosting site and use that URL in you emails.
Without the Premium Image Hosting, you can still host around 2MB of images or 50 images (whichever is reached earlier)
