That's great to hear! Unfortunately, some users experience difficulty sending email, especially to corporate/Microsoft owned services such as Hotmail. See the following threads for examples/anecdotes: email sent by GAE would be regarded as spam for some email services<https://groups.google.com/d/msg/google-appengine/azhX_BKiNiE/BFH-d67iu-cJ> SendGrid Integration<https://groups.google.com/d/msg/google-appengine/wUAgiyUiGHs/sivFLZPuMf8J> sending mail with google apps account from GAE application ends up in hotmail spam folder<https://groups.google.com/d/msg/google-appengine/wUi9qlG792g/BBES3T4ifz0J> Clearly PK, you're doing something right; maybe your email text is "unspammy", or perhaps many of your users are adding your email address to their addressbooks. But for others, using external mail services is much more straightforward and powerful; SendGrid in particular offers a bunch of useful analytics on their dashboard. ----------------- -Vinny P Technology & Media Advisor Chicago, IL App Engine Code Samples: http://www.learntogoogleit.com -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
