MailBee.NET Queue helps applications send e-mails faster by means of the background delivery. Instead of actual sending, your application can just write all the e-mails as .EML files into a certain folder, and MailBee.NET Queue will do the rest.

EasyMail SMTP Express is an e-mail queuing and delivery system. It rapidly accepts e-mail messages from the EasyMail SMTP Object, EasyMail .Net Edition SMTP assembly, EasyMail Advanced API SMTP library, FreeSMTP.Net assembly or other source, then queues and deliverers the messages in the background.

Add email (SMTP, POP3, IMAP4, MIME, HTML, SSL, S/MIME, authentication, attachments, bulk mailing), email address verification and bounced email management features to your .NET applications. EasyMail .Net Developer's Bundle includes EasyMail .Net, EasyMail.Net BounceBuster and EasyMail.Net Verify. EasyMail .Net fully supports SMTP, POP3, IMAP4, MIME, HTML, SSL, S/MIME, authentication, attachments, bulk mailing and much more. It includes support for .Net and the Compact Framework. EasyMail.Net BounceBuster enables your .Net application to parse, analyze and categorize bounced email messages. The information provided by BounceBuster can be used to update email address lists, create delivery reports and more. EasyMail.Net Verify enables your .Net application or website to validate internet email addresses. It can be used to clean your existing address list, validate email addresses entered onto web forms and more. It is a high performance, multithreaded, multilevel email address validation solution.
