How to send Mobile Email Using ExactTarget SOAP API?

Can I use Google App Engine to send mass emails?

• I am currently using 1and1Mail for email marketing. But I saw GAE is offering a Mail API that can send 2,000 emails per day free of charge. Anybody knows its deliverability? or inbox rate?

• Answer:

  yes it can be used but please note that there is one security restriction in Google App Engine "For security purposes, the sender address of a message must be the email  address of an administrator for the application or any valid email  receiving address for the app (see https://developers.google.com/appengine/docs/java/mail/#Java_Receiving_mail).  The sender can also be the Google Account email address of the current  user who is signed in, if the user's account is a Gmail account or is on  a domain managed by Google Apps."
