Planning to buy Email Spider

Hi there,

I am planning to buy this software. However, I have questions:

1. Is this fully functional without bugs? (e.g hanging, error pop-ups etc.)
2. Does it support HTML when sending out mails?
3. Can it scrape emails and sends it automatically?
4. Can I include a list of emails that I do not want to send to when sending emails? If yes, how?
5. Built-in scheduler for auto mailer?
6. Discount please?

Thank you!
