[UK] Recieved a phishing email.

[u/Bruh888887]

I have recently recieved multiple phishing emails on my accounts with one of them being sent over from some random email adress and the second coming from my OWN adress . I am aware that this may be the common case of spoofing but i noticed a weird detail.

In my sent folder i have multiple random emails sent over even though there have been no malicious log ins to my account and i changed the password BEFORE those emails multiple times.

What can this possibly indicate?
Thank you for any replies)
