yes, The main issue will response times if you a send emails synchronously ( if you can you send async). Async will definitely scale better since the client isn't blocking a thread for nothing. Simultaneous clients should be no problem as long as you follow the same threading rules as everything else shared vars etc.

For high loads you should use messaging. There's a ton of stuff on the net about async programming but it really depends on your environment. For a full JEE setup I'd probably use a Message Driven Bean. What sort of volume are you looking at and what's the environment?

Hello
Is it possible to send an email within an action? How/What are the issues? Is this scalable? How does it play with the framework and multiple simultaneous clients? Any insight would be appreciated.
