Thus you’ll require a Gmail account, which is basic as well as cost-free to produce. Once you have a Gmail account sending SMTP e-mails with C# is a wind. The method is to make use of the System.Net.Mail namespace as opposed to System.Web.Mail. The 2nd namespace was changed by System.Net beginning on .NET Framework 2.0.

But what do you do to link to Google’s web server? You require a couple of little bits of details. The initially is that Gmail’s SMTP web server address is smtp.gmail.com. The 2nd point you require to understand is that the C# application should link with port 587. How do we understand this? The details is offered to programmers easily by Google. Other SMTP web servers additionally give their very own address as well as port to get in touch with.

However there is still another point, a lot of SMTP web servers require verification to send your e-mails. This is where the Gmail account enters into play.

For instance, establishing the From area to another thing will certainly be overlooked by GMail, which will instantly establish the From area to your email address.

Lastly ensure SSL is made it possible for on the C# application. SSL is a security method as well as it is definitely needed or Gmail’s web server will certainly decline your link.
