What do you hope to get out of listing it? If you hope to get customers - You're thinking about it wrong. First, the typical buyer doesn't trawl a "SaaS Apps" list site looking for services they need. Second, even when you list on a site like Product Hunt, the chances are low that any given visitor that sees your site the day it's promoted also needs your service. Instead, think about what search terms someone might use on Google when they have (or are about to have) the problem your SaaS app solves. Try and write the best answer on the web for those searches. If you hope to get feedback - Again, probably thinking about it wrong. I'd try finding people who A.) You don't know and B.) Are uniquely qualified to give feedback on your service, and get in touch with them, try and offer something of value to them in exchange for feedback.
