Unfortunately, I can't give you insight specific to your tasks since they are US only (btw, if you don't specifically need US workers, maybe open your HITs to other English speaking countries (mainly Canada)), but I usually appreciate requesters who are responsive to workers and have had multiple long email chains with requesters on how to improve their tasks and it's appreciated when they want to improve the work they post. Concerning asking for reviews: Like others have said, a simple message welcoming reviews to help you improve your tasks and help other workers would be perfectly fine. While I would normally agree to the idea of giving an incentive to workers for their work, in the case of reviews, I agree with others that it could be seen as "buying reviews" which isn't a good look, so a simple message is more appropriate. I would however try to make it a bit apparent or maybe on a page before the survey code, because once I get the survey code, if I don't see an arrow at the bottom of the page, I rarely bother reading the info on that page (as it's very often a debrief or links to websites in case I was triggered by something in the study, so I don't usually read it). Based on the current reviews on TV, I'd say I strongly recommend increasing the pay to minimum >$15/hr (based on the most recent reviews, you are oscillating between ~$7 and ~$21/hr, with most people falling under the $15 mark). I can only speak for myself here, but I usually don't even bother trying to catch tasks that are averaged at <$15/hr and if I accidentally catch one, I will usually return it as soon as I see the reviews. It usually takes a requester being at an average of >$20/hr for me to want to do the work. Work between $15-20/hr, I will do on slow days only. Also, if a survey requires writing (other than a short 1-5 word answer), I normally return it as soon as I hit that writing section unless the reviews shows it pays well above the $30/hr mark (my process will usually be to get frustrated (if the writing sections is not announced at the beginning), tab out of the survey, hover over the return button, think I'll look at the reviews, see it's at like $40/hr and begrudgingly tab back to the survey and put some thought in the answer). I know I don't really care about giving my email address (or more specifically, using mturk to message a requester), but I know multiple workers who really don't like having to use the feature because of privacy concerns (some don't even want to contact a requester asking to overturn an unfair rejection because they don't want to send an email from their personal address), so another way of getting some feedback would be to include a feedback box in the survey. This way, you can get some feedback, it's easy to bonus workers for their feedback (without it seeming like you are buying reviews) and it gives you the opportunity to reply to that feedback in the bonus message. Hope this helps a bit.
