Spam Email Tips

Spammers like to validate that you read your email. They get a lot of satisfaction from this. Also they sell the data. Reading email isn't inherently bad like it was in the past, but there are still some pitfalls such as executing Javascript or loading remote images. Gmail strips Javascript so your'e good there. But they do load remote images by default. From Gmail help:

Choose to show or not show images

1. Open Gmail.
2. In the top right, click Settings .
3. Click Settings.
4. Scroll down to the "Images" section.
5. Select Always display external images or Ask before displaying external images. If you chose the "Ask before displaying external images" setting, messages that have images will have a "Display images below" option.
6. At the bottom of the page, click Save Changes.
