Possible to use gmail for website generated php mail?

creating a landing page that sends an email when people submit their address. I'd like to avoid having to set up an ema开发者_如何学Goil server. Is it possible to use gmail to send the emails generated by the website?

You can code this yourself to connect to Gmail or any other mail server you have access to as Dagon linked to in his comment.

Or you can use a service with an easy API like Sendgrid or EmailYak (has a free plan)

Using an outside provider like those two is usually much quicker and reliable.
