Hi, my question is: Can I send a newsletter to all my webpage's user? that means, multiple E-mails, I'm asking this because I was on other hosting and that didn't allowed me to do it.
That should be fine. Just check that you're not breaking the Acceptable Use Policy or the Terms of Service. http://x10hosting.com/aup http://x10hosting.com/terms
To be safe, cap yourself at 100 emails per day max, or the system may suspend you automatically.
