It should be possible in settings to modify the spam settings (web mail) so that spam emails are tagged but delivered to the inbox, thus preventing them going to spam. I get no spam emails sent to the spam folder, all go to the inbox which is my preference, and I can decide is the spam needs deleting out.
If using an email client, the spam filtering may need to be set up so look at options in settings.
It is a common problem with most email providers that genuine emais can go to the spam folder and will delete after a period. Some providers offer a choice of what to do with spam emails, as does virgin media.
Some emails are recognised as spam if they do not conform to email rules although they are not spam, it is the way they are configured, so always wise to check spam filter settings to avoid losing these emails.
I often get the odd genuine regular email going to spam on the odd occasion, but also a lot of nasty spam is also tagged spam but delivered to my inbox, such as bank scam phishing emails etc. for a lot of different banks.
Spam detection is never perfect, so best to check email regularly and check the spam folder as well as the inbox each time to check for any glitches.
Some spam emails can look identical to a genuine email and are phishing emails, so check the sender email address and headers to be sure it is genuine.
As the VM email is is no longer offered to new customers, the email service may be in decline/phased out in the future, so wise to have alternative email providers as I have now done.
I do however monitor my virgin media spam emails for anything suspicious.
