Callback Campaign information.

I just sent out a callback to a friend who has been unsubscribed since late 2015 maybe early 2016. I sent the request out around noon PST Mon Jun 26.

A quick search on the topic shows that the e-mail gets sent out on Tuesdays. And a thread here suggests that the e-mail may skip that date if the callback is sent out too close to that upcoming Tuesday.

I've done a brief runthrough of this on these forums, and the general consensus is to just wait it out. So can anyone provide some first hand experiences of when they actually got their callback e-mail?

My buddy is getting pretty excited about playing the game again, and wants to help me get some gold feathers. This process is pretty infuriating.
