Seeking Examples of Integrated Campaigns for Expansion

Hi everyone - we are just starting our lifecycle efforts and are first focused on expansion.
Does anyone have any examples they can share of an integrated campaign that worked well, including in product messages, emails, webinars, paid ads, 1:1, etc? I'd like to paint a vision of where we could be in 6-12 months across teams. One of my challenges is that people are working in silos and I want to get everyone inspired to work together. Thank you!
