Keith Martin (ID: 000000c1ff102a70) Voted 5 ★ - Updated 01/05/2024 Hi, Just over two years ago I suddenly started to receive spam emails in their hundreds! I enrolled with Blocksender and as more spam came into my computer I blocked them and requested to have the false notice sent to them. Gradually over time the spam started to reduce and now I am not getting any at all. If you do your bit and enter every spam email the system works!!! I am now not needing Blocksender so their success has meant they are losing a customer but I would not hesitate in renewing Blocksender if I ever start receiving spam again.
