We've been running adult traffic for a few years and postback setup has always been the thing that eats time when you onboard new partners. Either the docs are outdated, support takes days to respond, or something breaks and you spend hours debugging why conversions aren't firing. With Marksel the S2S setup was straightforward, when we had a question during integration someone actually got back to us same day. API tracking works cleanly across our offer stack, no discrepancy issues we couldn't trace. For adult and dating having solid tracking that just works matters more than most features on the feature list.

Marksel is pretty straightforward to work with day to day, and it’s nice not having to jump between multiple tools. The reports are clear, API offer connections save a lot of setup time, and the domain alerts are genuinely useful. You get notified fast and can fix things before they turn into a bigger problem.
