>>Second table needed because if I need to do a select SQL it will be speedier to get the needed informations I have to send to the customer from the first table. Second table would contain references to all the emails that were sent over the years. So each new year I transfer (add) references of what was sent the preceding year.

I guess that I should begin with one table and if there's a problem eventually I'll just have to adapt and modify the structures. Thanks for that feedback.
