MailVolt

Modern .NET email library. Drop-in replacement for FluentEmail.

Why MailVolt?

Quick Start (AutoConfigure)

dotnet add package MailVolt.AutoConfigure

{
 "MailVolt": {
 "From": { "Address": "noreply@example.com", "DisplayName": "My App" },
 "Transport": "Smtp",
 "Templates": "Razor",
 "Smtp": {
 "Host": "smtp.mailtrap.io",
 "Port": 587,
 "Username": "USER",
 "Password": "PASS"
 }
 }
}

// Program.cs — one line, everything from config
builder.Services.AddMailVolt(builder.Configuration);

Switch providers without changing code — just update Transport in config and add the matching section. Supports: Smtp · SendGrid · Mailgun · Resend · Postmark · Azure · Brevo · AwsSes · InMemory

Quick Start

// 1. Install
// dotnet add package MailVolt.Core
// dotnet add package MailVolt.Transport.Smtp

// 2. Register
services.AddMailVolt()
 .UseSmtpTransport(options =>
 {
 options.Host = "smtp.example.com";
 options.Username = "user";
 options.Password = "pass";
 });

// 3. Send
var builder = services.GetRequiredService<IEmailBuilder>();
var result = await builder
 .From("sender@example.com")
 .To("recipient@example.com")
 .Subject("Hello from MailVolt!")
 .HtmlBody("<h1>Welcome!</h1>")
 .SendAsync();

Batch Sending

var result = await batchSender.SendBatchAsync(emails, new BatchSendOptions
{
 MaxConcurrency = 10,
