How do you resize photo's sent through emails?
First you have to save the photo. Depending on the email program, this means right click on the image and chose "save as" or using the menu option "copy attachment". Now you have the image on your computer, for example in my documents and ca resize it as you do with any regular image file (see the linked article for an answer to that).
Is it illegal to view your emails lets say i left my email open then the person got on and searched through my sent emails is it illegal?
Email advertising is the advertising emails sent out to a list of subscribers who have shown their interest in the advertised product or service. The content of these emails are relevant to the recipient's interests and needs. Spam are the advertising abusive emails that don't provide relevant information to the recipients and they are sent out to huge mailing lists with very high frequency.
