There’s a Better Way to Send Email in C#

Sending email is a very common need for C# applications. Think about some of the use cases almost every app needs to handle: new user welcomes, event notifications, password resets, and so on. These transactional emails are workhorses, and it’s really important that they get to your users. As a C# developer, what’s the best way to get them done?

There are several C# email libraries out there, including system.net.mail, systems.web.mail. SmtpClient, MailKit, MimeKit, etc., but they all have one thing in common: you need an SMTP server to use them. Even if you have access to a server, it’s probably not tuned to ensure your messages get to your user’s inbox quickly and consistently. Using the SparkPost email delivery service is an easier way.

Let’s give it a try. Here’s how to send a message using SparkPost and C#.

You don’t have to manage any servers, monitor any services, or worry about whether the message will reach its recipient. You take care of deciding what to send and to whom, and SparkPost takes care of the rest.
