Unsubscribe only really works for professional business spam. Mainly confirms your email address has someone that is at least looking at the emails.
Have had my current email account and address since 1990. At one point the anti-spam service I was using (Barracuda) told me I was getting a million spams a day, A DAY!
Have hosted email since then as well. Host email for 4 companies. Have used various spam filters both on my mail servers and hosted. Currently using Canit by Roaring Penguin. It is a hosted service so keeps the spam traffic off the server network. Rarely get spam to my inbox. Receive a quarantine message once a day listing 5 to 10 emails. Only a couple of times a month does it quarantine good emails. It is VERY affordable.
I worked with their support to set up a few rules that greatly reduced even quarantine. Some of my users were receiving over 400 spams a day that got past the other spam filters I have tried. Now they are seeing what I do. A comple per month to their inbox and a few a day to quarantine with very few false positives. There were a few rules I had to set up to keep from blocking some email, but it was because their corporate email servers were set up so poorly.
Be happy to talk to you about it, or even host your email.
