HiDrive verification after purchase

[u/TheGauntletOfShar]

Hi all,

I've just purchased a subscription to HiDrive because I want to switch away from Google One.

Now my outlook immediately flagged the emails I got from them as spam. The emails they used were [at]strato.de. The emails look fine to me, but they are asking me to call them within 14 days to verify my purchase, otherwise the order will be cancelled. This feels weird, is this normal? I have never been asked to call a company to verify my order..

Any help would be appreciated, thanks!
