Free users are restricted to HTTP/HTTPS only, to a whitelist of sites. Because most email services work over SMTP, which is not HTTP or HTTPS, that means you cannot normally use SMTP on Free accounts.
If you want to send email, you have two options:
Use an HTTP/HTTPS-based email service (Services like Mailgun or sendgrid
        allow you to send email using HTTP(S) requests, and their API endpoint
        are on our whitelist. This is the most reliable option, and works well
        so long as your code isn't limited to using SMTP.)
