Warning though, use a disposable email, Daz spams the hell out of you.
Since I only found out about this like earlier this year, I'm always eager to share it...
Gmail "ignores" periods in an email address, so if your email address is firstname.lastname@example.org, you could give a particular survey or website (Daz in this case) an email address like email@example.com (since Gmail "ignores" periods, this is delivered to your firstname.lastname@example.org account) and then setup a filter to throw messages sent to that address in the trash or if you want to keep them and potentially review them later, you could add a label to them (label named 'Daz' here) and set the emails to skip the inbox.
Then you could go under that tag and review the emails or nuke them all or whatever you feel is appropriate.
Just a nice tip for throwing together a quick burner email address.
