First, you need to get an API key, which is available in the Resend Dashboard.
In the startup of your application, configure the DI container as follows:
using Resend;
builder.Services.AddOptions();
builder.Services.AddHttpClient<ResendClient>();
builder.Services.Configure<ResendClientOptions>( o =>
{
o.ApiToken = Environment.GetEnvironmentVariable( "RESEND_APITOKEN" )!;
} );
builder.Services.AddTransient<IResend, ResendClient>()You can then use the injected IResend instance to send emails.
Send your first email:
using Resend;
public class FeatureImplementation
{
private readonly IResend _resend;
public FeatureImplementation( IResend resend )
{
_resend = resend;
}
public Task Execute()
{
var message = new EmailMessage();
message.From = "[email protected]";
message.To.Add( "[email protected]" );
message.Subject = "hello world";
message.TextBody = "it works!";
await _resend.EmailSendAsync( message );
}
}Send an email custom HTML content:
using Resend;
public class FeatureImplementation
{
private readonly IResend _resend;
public FeatureImplementation( IResend resend )
{
_resend = resend;
}
public Task Execute()
{
var message = new EmailMessage();
message.From = "[email protected]";
message.To.Add( "[email protected]" );
message.Subject = "hello world";
message.HtmlBody = "<strong>it works!</strong>";
await _resend.EmailSendAsync( message );
}
