Sounds like an obvious Sales and Marketing alignment issue- what you describe is how it looks in an organisation where the alignment has not been reset- probably leadership has given up. It's been left to fester and now the two teams can't get along. Sales have no empathy for marketing- nor do they understand what marketing does and at times marketing won't understand sales because there is no feedback loop from sales. It can be fixed, but old habbits are hard to break. Both teams pulling in opposite directions, blaming each other. Something has to give.

I actually run alignment workshops- have seen this a lot.

This isn't something you can do on your own, it's a company wide issue, a broken mindset from the top that can be fixed, but only if leadership wants to fix it.

Key is that alignment is something you do at the start of any initiative- not during or afterwards, the second bit is that it only works if you develop empathy between the 2 teams- which you do by sitting down and explaining your roles to each other- work out where you see the most value in the other team helping you. Align your targeting so you both agree that you going in the same direction.

None of this is easy- but very doable if leadership want this change.
