Hie Actually that was my worry as well like sending through app engine may mark emails spam and thus wasting our efforts.
We ocassionaly send newsletter to all our subscribers and for that we are already using VerticalResponse.com which gives us 10000 emails credit every month for free being a non profit. Right now, we want to handle use cases like: " Sending email once a month to all the blood donors to verify/update their profile" So, if we use any 3rd party system then any recommendations? If non -profit friendly then that would be awesome! Vik On Sunday, 8 July 2012 09:13:15 UTC-7, Jeff Schnitzer wrote: > > I should add that we also use a third-party email system.
