MailKit vs PHPMailer: What are the differences?

What is MailKit? A cross-platform .NET library for IMAP, POP3, and SMTP. It is a cross-platform mail client library built on top of MimeKit. The main goal of this project is to provide the .NET world with robust, fully featured and RFC-compliant SMTP, POP3, and IMAP client implementations.

What is PHPMailer? The classic email sending library for PHP. A full-featured email creation and transfer class for PHP. It is a class library for PHP that provides a collection of functions to build and send email messages. PHPMailer supports several ways of sending email: mail() , Sendmail, qmail & direct to SMTP servers.

MailKit and PHPMailer belong to "Email API" category of the tech stack.

Some of the features offered by MailKit are:

  • SASL Authentication
  • Supports S/MIME v3.2
  • Supports OpenPGP

On the other hand, PHPMailer provides the following key features:

  • Integrated SMTP support - send without a local mail server
  • Send emails with multiple To, CC, BCC and Reply-to addresses
  • Multipart/alternative emails for mail clients that do not read HTML email
