Whenever I get an email from xxx@example.com (specific filter) I want to automatically send an email message to other email address. Not to forward the mail but to send a notification like "you have a new message with the filter "xxx" in the mail box yyy@example.net).
I tried to add filter and used canned response but it is only for "response".

I ran into the same issue here 5 years later. Neither Gmail or IFTTT solved the problem for me.
I signed up on https://zapier.com/ using my Google account. Using this, I was able to make a "zap" that's triggered when a specific email comes in and responds to the trigger by sending an email of my choosing. It was fairly straight forward to set up and surprisingly testable.
EDIT: I do not work for Zapier, I just solve problems and want to contribute here.
