Top 18 C# Email Projects

  • MailKit

    A cross-platform .NET library for IMAP, POP3, and SMTP.

    Project mention: UTF8 encoding in send-mailmessage doesn't work. | /r/PowerShell | 2023-06-09

    Third, Send-MailMessage has been deprecated. Try MailKit instead. To be honest, though, I'm yet to find time and test it myself.

  • FluentEmail

    All in one email sender for .NET. Supports popular senders (SendGrid, MailGun, etc) and Razor templates.

    Project mention: Sending HTML based emails. Is there an easier way to dynamically generate the document? | /r/csharp | 2023-05-15

    Surprised no one has mentioned this- https://github.com/lukencode/FluentEmail

  • Mergify

    Updating dependencies is time-consuming.. Solutions like Dependabot or Renovate update but don't merge dependencies. You need to do it manually while it could be fully automated! Add a Merge Queue to your workflow and stop caring about PR management & merging. Try Mergify for free.

  • MimeKit

    A .NET MIME creation and parser library with support for S/MIME, PGP, DKIM, TNEF and Unix mbox spools.

  • sendgrid-csharp

    The Official Twilio SendGrid C#, .NetStandard, .NetCore API Library

    Project mention: How do I make my own chat application for my remote friends to use? | /r/csharp | 2023-06-04

    There’s a bunch of communication software listed there. notifications Looks like the only C# one for custom communication software.

  • PreMailer.Net

    C# library that moves your stylesheets to inline style attributes, for maximum compatibility with E-mail clients.

    Project mention: Preview rendered .cshtml with the same style restrictions that email clients use | /r/dotnet | 2022-12-17

    If you don't already know about it, go check out PreMailer.net. It's a handy tool you can use to adjust styles to be more likely to work in email clients.

    Project mention: Ask HN: Are there any free email providers in 2023? | news.ycombinator.com | 2023-05-02

    I use AWS SES for sending and receiving (awkwardly) email for essentially free on several domains. I put together this repo to share how it works, which isn’t for everyone (but I certainly enjoy it). While it isn’t a polished experience it is very, very robust when deployed to multiple regions.
