What are the alternative ways to send mail from the site?

Question

Email

The question is in the title.
On the hosting, sending mail was blocked, and it is essential for automating the site (account confirmation, etc.). Tried scripts mail(); and send smtp - didn't help...
Are there any solutions through some third-party resources, for example, make a request to some site with send parameters and have it do it?
Mb there are other options?

                  $transport = Swift_SmtpTransport::newInstance('smtp.mandrillapp.com', 587);
                  $transport->setUsername($MANDRILL_USERNAME);
