Send time optimization in camapaign

Hi,

the sent time optimization (STO) feature would be very useful for us to sendout campaigns.
This feature should work in this way: it should keep trace of the time at which users usually open the emails and automatically send the email at this specific time that is different for each user.

For example: user X always opens newsletter around 11 am and user Y around 10 pm. When you set the sendout time for the newsletter you'll set a time frame of 24 hours and the tool automatically send the newsletter at the correct time for each user (so, in this case, 11 am for user X and 10 pm for user Y).

So, regardless the timezone, each user will receive the newsletter at the time at which he usually opens. It would be something much more "customized" than the timezone.

Thank you,

Elisa Pellacani
