Curiosus.EMail.Mailgun

NuGet Downloads Coverage

Mailgun implementation of IEMailSender from Curiosus.EMail. Sends messages through the Mailgun HTTP API (US or EU region).

Known issue: in the current version MailgunEmailOptions.AssertValid() throws NotImplementedException, so registering or constructing the sender fails. Use another IEMailSender provider until it is fixed.

Installation

dotnet add package Curiosus.EMail.Mailgun

Usage

Options (MailgunEmailOptions, validated on registration):

Mailgun:
  MailgunRegion: US                # US (default) or EU
  MailgunUser: api                 # required, basic auth user
  MailgunApiKey: <secret>          # required
  MailgunDomain: mg.example.com    # required
  EmailFrom: noreply@mg.example.com # required
  ReplyTo: support@example.com     # optional
  IgnoreIncorrectExtraParamsType: false

using Curiosus.EMail;
using Curiosus.EMail.Mailgun;

var mailgunOptions = builder.Configuration.GetSection("Mailgun").Get<MailgunEmailOptions>()!;
builder.Services.AddMailgunEmailSender(mailgunOptions); // IMailgunEmailSender and, by default, IEMailSender

// in a service that receives IEMailSender sender
var response = await sender.SendAsync("user@example.com", "Welcome", "<p>Hello!</p>", isBodyHtml: true, ct);

// use another domain/key for one message
await sender.SendAsync("user@example.com", "Report", "See attachment", false,
    new MailgunEmailExtraParams(mailgunDomain: "reports.example.com", emailFrom: "reports@reports.example.com"), ct);

HTTP 420 from Mailgun is returned as EmailError.RateLimit; other unsuccessful responses as EmailError.Auth. Pass useAsDefaultSender: false to register only IMailgunEmailSender.

HTTP requests go through the HttpClient named MailgunEmailSender.HttpClientName from IHttpClientFactory, which AddMailgunEmailSender registers. Configure it for timeouts, a proxy or resilience handlers:

services.AddHttpClient(MailgunEmailSender.HttpClientName, client => client.Timeout = TimeSpan.FromSeconds(30));
