Fluent.NET Mail takes advantage of the built-in .NET API and provides the ability to construct and send emails very easily. The messy work is taken care of in the background and allows the coder to focus on easily constructing and sending emails. Use custom templates with the dynamic substitution of data, send mail in various formats (text & HTML), choose your means of transportation (SMTP, Network, Pickup), use security certificates, use SSL, include attachments, send mail asynchronously plus all the other features provided by the .NET framework.

Check out Web Miner, a real world web content mining application which takes advantage of Fluent.NET Mail. See an application preview here. The email miner takes advantage of this fantastic component by sending out templated emails.

2.0, November 3rd 2014


  • Upgraded from .NET 2.0 to .NET 3.5 (This is necessary to satisfy a more complex architecture without hacks that cause potential conflicts and warnings)
  • Split architecture into 3 parts (Composer, Distributor, Public API). This change allows both the existing way of using the API and the more granular approach
  • Email building can now be done through the Composer class
  • Email distribution can now be done through the Distributor class
  • Added [BindingName] attribute to override the default property name when substituting values in the template
  • Added the ability to Clone a MailBox through implementation of the ICloneable interface
  • Added the ability to clone a MailConfiguration through implementation of the ICloneable interface
  • Added the ability to clone a MessageTemplate through the implementation of the ICloneable interface
  • Expose the MailConfiguration class which is used the maintain the configuration of a FluentMail instance.


  • Minor performance improvements
  • Set defaults for SMTP port if not provided using the values 465 if SSL is requested else 587.

Bug Fixes
