## What it is
FluentEmail is an all-in-one email sending library for .NET and .NET Core with a fluent API. It supports multiple senders (SMTP, SendGrid, Mailgun, MailKit, Mailtrap) and Razor or Liquid template rendering, with built-in dependency injection support.

## Use cases
- send email from a .NET application
- send transactional emails via SendGrid or Mailgun
- render email bodies from Razor templates
- send emails over SMTP in .NET Core
- inject an email sender service into ASP.NET Core apps
- switch email providers without changing application code

## When to choose
- you need a simple, fluent API for sending email in .NET
- you want pluggable providers like SendGrid, Mailgun, or SMTP
- you want templated emails using Razor or Liquid
- you want clean dependency injection and testability

## When to avoid

- you need bulk marketing campaign features
- your project is not on the .NET platform
