Leslie, if it helps, this is the same kind of email silence I ran into a week ago when purchasing a Commercial license, where you kindly stepped in to take care of the issue.
As you know, that went very well, and was handled by Private Messages on the forum here so we could talk.
However, I _never_ received any email then or later from you or sales, even at the time when you got further involved. As far as I know, nothing of the kind has ever happened for incoming mail on my prime address which I used.
I made the order sensibly using a separate Gmail address - this worked fine, and instantly.
Afterwards, I switched my forum mail here to use the original prime address as a test. Although never receiving any sales mail, from the forum this same address has been perfectly reliable from the first and since - including the marathon night where Lisa helped me to find the installation problems. I still use it.
The spam traps are administered by me, and nothing was lost in them. Also, tech support often enough speaks of using ‘alternate addresses’ as Lisa has here.
I may have confused matters at the time in privately mentioning to you about very occasional IP blacklist issues on a shared hosting. But this would not prevent receiving your mail—only you having received mine, and you were clear that you had received mine.
I would respectfully suggest then that something needs to be looked into as far as the EE sales mail. Good for you folks there, and thus good for us all.
Kind regards,
Clive
