There is actually quite a lot involved with email marketing to ensure it’s success. You can not just go and send off random emails and expect it to do anything. Your emails must be professional (but try not to sound stiff, if that makes sense) and informative. But at the same time you do not want to give them what you are selling (assuming what you are selling is knowledge), so you need to give them enough to whet their appetite but not so much that they feel no need to buy it.
If you take your own photos for your blog, you may have experienced how frustrating it can be to find someone else using your photos without even giving you credit. This plugin takes care of that problem for you. Instead of putting a watermark on every image manually, it automatically places a watermark on all the images on your site without affecting the original image.
