I've been getting emails at my work address for the past year from a company I don't remember subscribing to (especially not with my work email address). I've reported it as spam, but got a reply from my company saying it's a real company.
I'm dubious, and I've read that you shouldn't click unsubscribe from emails you don't remember subscribing to as it alerts spammers that it's a live address, so I set up a filter to auto-delete the emails.
However, the emails keep changing. The email address in the from field changes, or the name of the company changes slightly, etc. Eventually, new emails slip through, and I have to set up a new filter. Also, the URL in the unsubscribe link changes with every email. The email itself always contains a link to a document to read about the latest technology updates in (my field), but the URL always ends in
?email=(my email address)?from=(number). (At least I assume it's a document, I've never clicked on one.)
I feel like a reputable company wouldn't do something like this, and so I'm still hesitant to unsubscribe. The people the emails are from seem to have LinkedIn profiles, but I've also found some other posts suggesting it might be spam.
Am I being over-paranoid? Should I just unsubscribe?
In a more general case, what things can I do to work out if an email is safe to unsubscribe from?
