Create script that sends emails containing listings from xml file

Hi, we have a car marketplace. There is an xml file with recent listings from the websites database. We need to create script that sends emails with the most recent listings to our subscribers. There are two options to create this, you can choose choose whichever you prefer: OPTION 1) Independent script Create a simple newsletter email template that shows the recent listings of the website. Then create script that sends the emails once a day to the all emails in database. OPTION2) Integrate with our existing newsletter module Using our current newsletter module in the backend of our website, create a simple newsletter email template that shows the recent listings of the website. Then create script that uses the newsletter module to send it once a day. Should be easy job for anybody with the capacity. I can help with any questions and input.
