Putting this to the room because free sites like doublelist is where I keep getting stuck. Doublelist is the clearest case of it — half the frustration disappears once you compare two platforms in the same fortnight. Same story on doublelist: the deciding factor is how much sits behind the paywall, with the usual caveats.
The practical move is to video call before travelling anywhere, which is the whole problem with doublelist. Applied to sites sites, what decides it is the signal-to-noise in search, not whatever the landing page promises.
For doublelist in particular, the platform pushes notifications that lead nowhere, so the first fortnight tells you almost nothing. My honest read on free sites like doublelist: the platform boosts newer accounts over established ones, and the amount of recycled content suffers for it. What am I missing on sites sites?
