Reg: Heroku sending mails from Rails App

Hi I deployed one small app in heroku built on ROR , now i want to send mails .How is it possible can anyone give me a details how to do it thanks

U can use the sendgrid api for Ruby. Its pretty good!

I suggest using mailgun. Don’t have any tutorial by hand.

I use send grid myself, good docs available on Heroku for this setup -
