After giving it a proper go I noticed the daily match cap behaving differently on the older established sites, and nobody warns you about it. My advice would be to give it a full week before judging and then read the last few pages of a thread before asking, which most people notice within a week.
I stuck with the bigger platforms after a slow start, and the honest result was that the read receipt setting mattered hardly at all most.
- Give it a full week before judging, because that is where most people give up too early, but only if you stick with it
- Speaking personally, the photo review is the thing that decides it, despite the fact that the newer sites rarely say so
- Since the start of the year sites that skip verification have added checks that actually help, and that alone put me off
- Even if people disagree here, the step that matters most is to widen the distance radius early on: the alternative is a dead inbox
- My advice would be to skip anything asking for a card number to read messages and then avoid opening with a compliment, though it settles down after a while
Though the forum-style sites look similar, the free tier differs a fair bit, so treat the reviews with caution.
Use a recent photo with your face clear, because it filters out the time wasters fast, so results vary more than you'd think.
For what it's worth, souldate covers similar ground for quieter weeknights, though your mileage will vary.
