I feel like I probably have, at least in terms of newsletter-style emails, or maybe breach notifications? But no, I don't have an example handy.

Another example that comes to mind is Taiga and PenPot. Different products by the same company https://blog.kaleidos.net/Taiga-and-Penpot-lead-our-new-chapter-at-Kaleidos/ In my experience they do less cross-promotion than they probably could. I am just a dabbler in using both products. They may do more cross-promo than I've seen, or have good reasons for not doing more.
