Watched a founder in Austin lose his biggest client because of a 2 day email delay
His team was 5 people and everyone just assumed someone else would reply to the thread. Now he makes one person own the inbox every Friday, and I started doing the same thing at my shop.
That thing about everyone assuming someone else would reply is so real. We lost a lead once the same way and now we just rotate who checks email each day, takes like 10 minutes and nothing slips through. Maybe it's just me but one person owning it beats a whole team watching it.
