SyntaxCircus.Email

An email-sending abstraction: a MailKit-based SMTP implementation with retry, plus Null (dev) and in-memory (test) implementations. Templating and composition are out of scope on purpose — too product-specific to generalize; this only covers the send primitive and provider switch.

No support guaranteed. Published as-is and maintained on a best-effort basis. Issues and PRs are welcome, but there's no SLA — fork it or vendor what you need if that's not enough.

Usage

builder.Services.AddSmtpEmailSender(builder.Configuration); // binds "Email:Smtp"
// or, in Development: builder.Services.AddNullEmailSender();
// or, in tests: builder.Services.AddInMemoryEmailSender();

{
  "Email": {
    "Smtp": {
      "Host": "smtp.example.com",
      "Port": 587,
      "Username": "...",
      "Password": "...",
      "DefaultFrom": "noreply@example.com",
      "MaxRetryAttempts": 3
    }
  }
}

public sealed class WelcomeEmailService(IEmailSender emailSender)
{
    public Task SendWelcomeAsync(string to, CancellationToken ct)
        => emailSender.SendAsync(new EmailMessage(to, "Welcome!", "<p>Hi there.</p>"), ct);
}

SmtpEmailSender retries transient send failures with exponential backoff (MaxRetryAttempts, default 3). InMemoryEmailSender exposes SentMessages (and Clear()) for assertions in tests — resolve it directly (it's also registered as itself, not just as IEmailSender) when you need to inspect what was "sent".
