Acop (Acop.com) provides surveys to you over email. I have found it harder to be accepted onto these recently, to the extent my account is in abeyance right now, although I will state that when you are accepted, the rewards are decent. The surveys can be quite long, and you may sometimes be set products to test. They are a reliable payer, but as always income levels depend on how many surveys you are accepted for and can complete.
This doesn't have a standard referral program, although it is part of share-a-sale so if you sign up as a partner through them you can get a 1.00 per reputable and accepted sign-up. Currently they are looking for new members in the US, Canada, the UK, Germany, and France, so they will only accept partners recruiting in these areas.
This didn't really work out for me, but might be useful for others.
