CoreMailer for NET Core 3.1 and above

Based on Riyasat CoreMailer project, this package is meant to work with NET Core 3.1 LTS and above. Send emails from dynamic templates made with Razor.

IMPORTANT If you are using NET Core 3.1 and above you must configure your Startup.cs services to work with controllers & views, specially if the project was bootstraped to be a Razor Web App. Here we are using controllers & views to generate email views. More instructions below.

How to Use


Add package reference to your project .csproj file. For more installation methods refer to the package NuGet site.

<PackageReference Include="prosmart.CoreMailer" Version="1.0.0" />


In Startup.cs, ConfigureServices

TemplateRenderer & CoreMvcmailer services must be cregistered as scoped services.

REMEMBER as per docs of NET Core 3.x, MVC Registration had some changes. If you are using a Razor Page project or WebAPI-only you must register controllers & views in order to use this package. So, the final service registration section would be like this:

services.AddScoped<ITemplateRenderer, TemplateRenderer>();
services.AddScoped<ICoreMvcMailer, CoreMvcMailer>();

You can use this MVC Registration alongside Razor Pages, read the docs provided to understand these changes.

Then, register routes to this controllers in Startup Configure section.

app.UseEndpoints(endpoints =>
        name: "default",
        pattern: "{controller=Home}/{action=Index}/{id?}");

This is pretty straightforward and basic configuration for controllers, you can change this configuration as you need. Official docs are available here.

In your Views folder

Create a cshtml template under any views folder e.g.


This template will be associated to a model so we can change values dynamically.

The content of cshtml can be

@model UserRegistrationInfo
Hello <strong>@Model.UserName</strong> your email is <strong>@Model.Email</strong>

NOTE: For emails you have to use inline styling. This means that all CSS values must be inlined in your view file (or any HTML of some sort). For this task you can use Foundation for Emails or any web-based editor.

Usage in Controllers

Emails must be send inside a controller action, plain old MVC. Our mailer service is properly registered in our Startup.cs so we can use built-in DI in any controller constructor like this:


private readonly ICoreMvcMailer _mailer;

public HomeController(ICoreMvcMailer mailer)
  _mailer = mailer;

In ActionMethod Now you can send emails inside any action, in this example we use the SencAsync method:

public async Task<IActionResult> NotifyUser(string username, string email)
    UserRegistrationInfo newUser = new UserRegistrationInfo()
        UserName = username,
        Email = email 

    MailerModel notifier = new MailerModel("YourHostName",1234)
        FromAddress = "Your Address",
        IsHtml = true,
        User = "YourUserName",
        Key ="YourKey",
        ViewFile = "Emails/Register",
        Subject = "Registration",
        Model = newUser
    await _mailer.SendAsync(notifier);
    return View();


UPDATE 2018-01-04

Added support to use local folder instead of using paid or free mail servers.


It is really simple to use. Just create MVCMailer model with pickup directory location. When you send the email make sure you set sender and reciver email. Once done, you can see email in your provided pickup directory.

        MailerModel notifier = new MailerModel(**"Your Directory Here"**)
            FromAddress = "Your Address",
            IsHtml = true,
            User = "YourUserName",
            Key ="YourKey",
            ViewFile = "Emails/Register",
            Subject = "Registration",
            Model = newUser
