Hello Charles,

What email host and client are you using? If you are only using webmail, then there will be no client.

If you use Google Mail and the content of this spam email is always the same you could create a content filter for something like “The survey is short and will only take 2 minutes to complete.”
When creating the mail filter for this key phrase or “Has the words”, you can configure it to trash the email.

How to create a mail filter for a phrase.
