...Help - my gmail account is getting bombarded with spam!

Hi
Can someone help me?
Suddenly, my gmail account is getting bombarded with spam.
I can’t stop it - I keep getting a ton of spam.
It seems that somehow I have been signed up for every website in the world - see attachment.
I just discovered Spamsieve - will Spamsieve stop the spam from coming into my inbox?
Any suggestions?
Thanks

Yes, you can use SpamSieve with Gmail, e.g. through Apple Mail, and it will filter the spam messages out of your inbox.

Michael - thank you so much for taking the time to help me.
Question - once I download the app - does it need to be setup or configured to run?

Yes, there are instructions here.
