"How will messages be sent to the list?" is a pretty daunting question, but it shouldn't be too hard for you to answer. What kind of messages will you be sending?
If you want to send messages using our templates, with a lot of color, images and styling, you should select Listbox Composer Only. The one and only way messages can be sent to your list is through the Listbox website. You (or another list administrator) must log in to create, test and send messages. This is also the most secure option for sending mail to your subscribers.
If you need less sophisticated message formatting options, or you want to be able to send messages frequently throughout the day, choose Administrators can send email: This turns on your list ID as an email address. List administrators can then send messages to your ID @listbox.com. This allows you to send mail to your subscribers from Outlook, Mac Mail or another email client. (You can always use the Listbox Composer as well.) For your security, we will still send a "moderation request", which asks you to click a link to review a message on the web before distributing it to all your subscribers.
Selecting this option will reveal the Message Format settings page, where you can specify any formatting changes we should make to messages submitted via email.
If your list is actually a discussion forum, where everyone on the list should be able to post, select All Subscribers can send email. Anyone who is a subscriber of the list is able to send email to the List ID @listbox.com, and have their message distributed to all the other subscribers.
Selecting this option will reveal the Message Format settings page, where you can specify any formatting changes we should make to messages submitted via email, and the Posting Restrictions page, which allows you to prohibit certain types of messages.
