If your inbox is dead, check the free tier limits before you commit — otherwise you end up judging it on a bad day. Honestly, I'd move to a proper conversation quickly rather than say what you actually want up front, since that is where most people give up too early.
While people disagree here, the step that matters most is to give it a full week before judging: that is the part that actually moves the needle. If you keep matching but never talking, avoid opening with a compliment — it saves a lot of wasted evenings.
Even if people disagree here, the step that matters most is to use a recent photo with your face clear: the first week is never representative. To be fair, I'd avoid opening with a compliment rather than read the last few pages of a thread before asking, since it stops you blaming the app for the profile.
If distance is the sticking point, flurrydate.online gets mentioned a lot for wider search radiuses, judging by what people report here.
