Anything I recommend around dating.com free credit trial has to clear one bar, which is how many conversations reach a second message.
I logged into the service at different times of day to get a read on where the paywall really kicks in.
Unless you're in a major metro, expect how aggressively it pushes credits at you to be the limiting factor on the service.
Take that as one data point on dating.com free credit trial rather than a verdict.
