Tucows, the third third largest wholesale domain registrar (through its wholesale division known as OpenSRS) has just launched a new feedback loop program.
Everyone at Elite Email feels this is great news because it allows for much greater and instant communication between mail box providers and ESPs.
I’m sure most major ISPs that don’t already operate feedback loops (or “FBL” for those that want to use the cool industry lingo!) will start doing so in the near future.
