The email below is based on an actual email I wrote to a Hubspot Partner with whom I work. If you pick up some frustration in my tone, you are correct, but keep in mind that it is in good faith. I'm sharing this because I've seen this before and wanted to bring it to attention. By they way, if you work with another Channel Account Manager here at Hubspot, you should work more closely with them for the same reasons I list here. My colleagues are good at what they do.
Dear [Partner X],
