Search alerts emailing me over and over

[MajorMantra]

I have a saved search for Mk1 MX5s and the site keeps sending me emails regardless of whether new cars have been listed for sale. Today I received four emails, all linking me to the same 13 cars!

Can this be looked into? I want to use the classifieds but I'll have to unsubscribe from alerts if I keep getting spammed by them.

Cheers!
