In this Article we will
see how to send a email in dotnet 6.0 using MailKit email
client library.
Step 1:- Install MailKit via NuGet
.NET Core CLI: dotnet add package MailKit
Visual Studio Package Manager
Console: Install-Package
MailKit
Step 2:- Send an HTML email in .NET 6.0
This code sends a
simple HTML email using the Ethereal fake SMTP service, for quick testing you
can create a temporary inbox at https://ethereal.email/ and copy the SMTP
configuration options. There are instructions further below on how to use a few
other popular SMTP providers - Gmail, Hotmail, Office 365 and AWS SES.
|
// create email message var email = new MimeMessage(); email.From.Add(MailboxAddress.Parse("from_address@example.com")); email.To.Add(MailboxAddress.Parse("to_address@example.com")); email.Subject = "Test Email Subject"; email.Body = new TextPart(TextFormat.Html) { Text =
"<h1>Example HTML Message Body</h1>" }; // send email using var smtp = new SmtpClient(); smtp.Connect("smtp.ethereal.email", 587,
SecureSocketOptions.StartTls); smtp.Authenticate("[USERNAME]",
"[PASSWORD]"); smtp.Send(email); smtp.Disconnect(true); |
Send a plain text email in .NET 6.0
This code sends the same
email as above with a plain text body.
|
// create email message var email = new MimeMessage(); email.From.Add(MailboxAddress.Parse("from_address@example.com")); email.To.Add(MailboxAddress.Parse("to_address@example.com")); email.Subject = "Test Email Subject"; email.Body = new TextPart(TextFormat.Plain) { Text =
"Example Plain Text Message Body" }; // send email using var smtp = new SmtpClient(); smtp.Connect("smtp.ethereal.email", 587,
SecureSocketOptions.StartTls); smtp.Authenticate("[USERNAME]",
"[PASSWORD]"); smtp.Send(email); smtp.Disconnect(true); |
Send SMTP email with Gmail, Hotmail, Office 365 or AWS SES
To change the above code
to use a different email provider simply update the host parameter (the first
parameter) passed to the smtp.Connect() method, for example:
|
// gmail smtp.Connect("smtp.gmail.com", 587,
SecureSocketOptions.StartTls); // hotmail smtp.Connect("smtp.live.com", 587,
SecureSocketOptions.StartTls); // office 365 smtp.Connect("smtp.office365.com", 587,
SecureSocketOptions.StartTls); // aws ses (simple email service) smtp.Connect("email-smtp.[AWS
REGION].amazonaws.com", 587, SecureSocketOptions.StartTls) |
Send email using Email Service interface
To
encapsulate the email sending functionality so it's easy to send email from
anywhere in your .NET app you can create an EmailService class and IEmailService interface like below.
|
namespace
WebApi.Services; using
MailKit.Net.Smtp; using MailKit.Security; using
Microsoft.Extensions.Options; using
MimeKit; using
MimeKit.Text; using
WebApi.Helpers; public
interface IEmailService { void Send(string to, string subject,
string html, string from = null); } public class
EmailService : IEmailService { private readonly AppSettings
_appSettings; public
EmailService(IOptions<AppSettings> appSettings) { _appSettings = appSettings.Value; } public void Send(string to, string
subject, string html, string from = null) { // create message var email = new MimeMessage();
email.From.Add(MailboxAddress.Parse(from ?? _appSettings.EmailFrom));
email.To.Add(MailboxAddress.Parse(to)); email.Subject = subject; email.Body = new
TextPart(TextFormat.Html) { Text = html }; // send email using var smtp = new SmtpClient(); smtp.Connect(_appSettings.SmtpHost,
_appSettings.SmtpPort, SecureSocketOptions.StartTls);
smtp.Authenticate(_appSettings.SmtpUser, _appSettings.SmtpPass); smtp.Send(email); smtp.Disconnect(true); } } |
