Choosing between Swift Mailer and PHPMailer .

Please share your experience.
Does one of them have an advantage over the other?

I want to note that more than a year has passed since the last release of each of the libraries, perhaps they have worthy competition.

Answer 1

Swift Mailer is better in my opinion. Work raises no objections.
The advantage in my opinion is one of the most important: it is support for plugins.
That is, I advise Swift Mailer!
