Increase the Throughput
EasyMail SMTP Express speeds up e-mail delivery by offloading the delivery task from your application.   The standard version sends up to 64 messages simultaneously.  The Pro version handles up to 256 simultaneous messages and is loaded with additional features.

Increase the Reliability
SMTP Express is an e-mail queuing and delivery system.  It intercepts messages from the EasyMail SMTP object, EasyMail .Net Edition SMTP class, EasyMail Advanced API SMTP library or other source and sorts, queues, and reliably delivers the messages in the background.
