DataBack Systems LLC

	Easy-to-use listowner web interface	Click here to see an example of the DBMailer discussion listowner interface in a new window. Add and remove subscribers, edit confirmation and welcome messages via a straightforward web interface.
	Owner-defined welcome and farewell messages	New subscribers are sent a welcome message. Those who chose to unsubscribe are sent a farewell message. Both messages can be fully customized or they can be eliminated if you prefer.
	"Confirmed opt-in" subscription process	The initial subscription request generates a confirmation email. The potential subscriber must reply to that message to confirm the subscription. Click here for a description why this is required and desirable. For private discussion lists, you may choose to not publish any subscription instructions but add subscribers only via the listowner web interface.
	Digest Included	A digest is a single daily message including all posts from the previous day. Subscribers can switch to/from digest mode at any time. This is a standard feature of DBMailer discussion lists.
	List headers in your domain	Simply create email aliases which point to addresses on our server, and all visible, published addresses can be in your domain name. References to DataBack are then only found in the (normally invisible) full message "Received" headers. Add a "Reply-To" header if you want to force replies back to the discussion list.
	Optional settings	Posts are accepted only from subscribers or other specially authorized addresses. This prevents most spam from reaching your list.
	Subscription interface for your web site	Add a simple signup form to your web site easily. Instructions for installing a signup form on your web site can be found here. More complicated subscription forms can also be supported via custom scripts.
	Automatic bounce handling	Bounces (undeliverable messages) are returned to our server after each mailing, not to you. When an address bounces for two days in a row, it's automatically removed. Removed addresses are reported in the daily report.
	Optional "demime" filter	Optional ($10/month extra): Filter all posts to remove formatting and attachments, converting them to text-only. Makes digest readable and makes all messages readable by all subscribers regardless of email programs used.
	Easy unsubscribe	A subscriber writes to a list-specific "leave-" address to be automatically unsubscribed. The farewell message is sent to confirm the subscriber's removal from the list.
	Affordable	DBMailer discussion list service is $15.00/month for each 100 subscribers. Invoices are sent via email quarterly in advance. There are no setup charges and no minimum terms or agreements required. For discussion lists, DBMailer is a quarter-to-quarter service.
