Mail rules accidentally deleted all of my emails. How to restore?

Alright, here goes.

I tried to set up af number of rules in my Mail application (just the standard one), that would delete some "subscribtion emails" that I never read anyways. And no, it's not spam.

BUT, I accidentally forgot to set the "any" criteria to "all", which means it all of a sudden deleted all mails with my email address as recipent. How can I restore them? They do NOT appear in my "Deleted messages"!

Also, is it really true that such a simple user mistake, can cause the user to lose highly important emails? I mean... It's like one click away from utter and permanent removal of the emails. If that's the case, I am really disappointed in Apple. I know I made a mistake, but forgetting to set "any" to "all" is something I feel anyone can do on accident, since it's on "any" as default. And it just applies the rule to the whole mailbox! I had no chance to stop it, and now my mails are gone. Important ones from the government, tax-mails, receipts... all just gone.

And no... I do not have a backup of those mails. I am without a time machine harddisk, and I honestly thought that deleted mails would appear in the "deleted mails" folder on iCloud, but they do not. The rules must have deleted those two, even though I have no idea why and how that should be possible.

And yes, the emails are gone from ALL of my devices, and not just the Mac... even iCloud.com does not have any trace that they even existed.

Please help, I know I haven't been smart about it, but permanently deleting such a large amount of emails, without warning or recovery method, simply should not be possible!

Any support is highly appreciated. I am looking at a world of s*** if I can't recover some of these important emails. Thank you in advance!

🙂 And here's a smiley, so you know that I am normally a very happy guy, and so you also know that I will be immensely joyful and appreciative of your help 🙂
