Rails3 and Heroku: Sending Emails?

I have deploy开发者_JAVA百科ed my Beta App to Heroku and am reading their articles about sending emails. I don't imagine I will be generating more then 100 per day. There seems to be 2 routes they suggest:

1) their sendgrid add-on Article

2) using gmail Article

3) I have my own non-rails web hosting package - could I use this?

Does anyone have experience of using either of these? Which is considered better/easier to manage?

On Heroku I would recommend Sendgrid over the Gmail solution. Sendgrid is well integrated and you won't touch the 200 emails limit.

Currently, I use both: Sendgrid with CommunityGuides on Heroku and Gmail for local testing. Sendgrid was painless to set up.
