Topic "Database design" a message from venom

Hello,

we would like to send an automated E-mail to a customer as soon as someone uses the connection.
At the moment we use a static to send a mail via batch which executes right before the session starts.

Now i need to know where the &quotinformation/email&quot part is located in the database, so I can call up a customers mail address dynamically.
How can I call up this information?

Or is there another way to send an automated mail?
