I get it, please see my other response. RE: random bash commands. Part of the reason I linked shopify's SPF page to them -- an attempt to provide external validation. But I get it. Which is why, as I mention in that other response, it doesn't matter what I send. Even pleas to forward to a technical person = ignored. (I bet lots of tech people get forwarded all sorts of crap that IS a scam, so yell "DON'T FORWARD THIS…
Tell them that you placed an order, and did not receive a confirmation email. If you really feel obligated, you can mention something about SPF settings, but I literally would not provide more detail than "it might be related to your SPF settings."
If you respond to that without technical data, then you're basically saying "No, I did not receive it", and their response is "Your gmail lost it" (because mail = gmail).
The problem is that emails sent with "I didn't get the confirm email" are immediately thought to be "user error". And you know what?
99.9999% of the time, they surely are. Bad email providers, lost in SPAM folders, even missed in INBOX.
So if you don't include tech info, you're stuck in this category, else many exchanges back and forth.
Because once I then respond with technical info?
You get the same glassy-eyed type of incomprehension, with often zero response. Or a response that invites another 5 back and forths, with the other side upset, because now they feel ignorant.
I feel there really is no proper answer here... except, I still have to try. :P
