The clause test is useful. Titles that describe what the thing does for one specific user tend to beat the ones listing features. Have you seen any difference between titles that name the tool you integrate with versus ones that stay generic?
Naming the integration seems to help when it's the reason someone would click, like the tool they already live in. When it's just part of the stack it's noise in the title. I don't have hard numbers on it though, it's more a pattern from reading the front page.
