SendGrid SMTP API

Question

I am using SendGrid and PHP (CakePHP). My server does not have SMTP enabled. Do I need smtp on my server to use SendGrid's SMTP API?

Answer 1

Disclaimer: I work at SendGrid.

Our SMTP API example recommends using the Swift_SmtpTransport library, which makes low-level socket connections to end systems. When configured with our example, Swift connects to our systems to deliver your message, and won't require an SMTP service on your end.
