I would judge free dating sites no charge for sending on how quickly it starts asking for money rather than on the feature list.
Two of us compared notes on the service and landed in the same place on how much of it's usable without a card.
If you can only manage a few evenings a week, what you lose by never upgrading matters more than raw volume on that one.
The short checklist I use before trusting anything like free dating sites no charge for sending:
- Whether free dating sites no charge for sending works at all outside the three biggest cities near you
- How many free dating sites no charge for sending profiles show a recent login rather than a join date
- How free dating sites no charge for sending behaves on mobile data rather than wifi
- Whether free dating sites no charge for sending shows you who has actually read a message
