This may sound like I'm a hired shill for another company's products, but if you have to send tons of emails to recipients on various email services, I'd recommend Amazon SES.
Especially if you are using App Engine Python. The boto lib (https://github.com/boto) can have you sending emails using SES in 30 minutes. Also, Amazon provides instructions to add SPF info for your domain, so mails are more likely to get to the recipient (still not guaranteed though). I was really pleased with how easy it was to implement. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
