Reporting & Statistics
You will get 2 reports letting you know how many spamming attempts were blocked in total and by type.
- The first report shows you the figures since you first installed the package
- The second report shows you figures for the last 31 days.
Here's a screenshot showing you the kind of results I got on my own website kalmoya.com:
3505 SPAM attempts were blocked from December 2, 2020, to August 18, 2021. That's more than 400 per month.

No anti-spam system is 100% foolproof. Anti-Spammer Master will do an excellent job blocking most automated spam and even some manual spam but your mileage will definitely vary.
