ruby on rails 3 - Rails3 and Heroku: Sending Emails? -

i have deployed beta app heroku , reading articles sending emails. don't imagine generating more 100 per day. there seems 2 routes suggest:

1) sendgrid add-on article

2) using gmail article

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

does have experience of using either of these? considered better/easier manage?

on heroku recommend sendgrid on gmail solution. sendgrid integrated , won't touch 200 emails limit.

currently, use both: sendgrid communityguides on heroku , gmail local testing. sendgrid painless set up.
