Quick answer
Most spam gets filtered properly with correct domain security settings (SPF, DKIM, DMARC) and good email filtering — not just by clicking "unsubscribe."
If you’re getting a lot of spam, it’s rarely “bad luck” — it’s usually missing security configuration on your email domain, or an outdated, low-quality email provider.
What actually helps
Microsoft 365 and Google Workspace both have strong built-in spam filtering — far better than older or free providers. On top of that, correct domain settings (SPF/DKIM/DMARC) stop others from sending fake emails “from you,” which often triggers a cycle of spam replies.
What to avoid
Never click “unsubscribe” on suspicious emails — that just confirms to bad actors that your address is active, bringing in more spam.
- Correct SPF/DKIM/DMARC setup on your domain
- A quality email provider with built-in filtering
- Never unsubscribe from unknown/suspicious emails — just delete
