Let's say I would like my campaign to be delivered on monday at 9.00am.
As my recipients can be in different timezones, I would like to automate the launch at the same hour for different timezones.
Actually, 9.00 am in UK means 1.00am in San Francisco, and lunch time in India, so there is a chance my campaign won't be read as much as if it was arriving at 9.00 am for everyone...
I think such a possibility could be quite useful
