Flyers... and Lurkers,

How long should I expect before my email get answered by my ambassador?
In most (if not all) of my email communication with my ambassador, at best, I get reply after 48 hours.

Is email not the preferred way to communicate with our ambassadors? I will be traveling internationally, and can't be expected to have phone connection, thus for me, email is the better way.

Should I be concern with my ambassador, or this is common?

Appreciate any info.
