I've lead customer comms at a couple companies and it's a consistent challenge. I'm working though it again now. We limit to "Marketing" 3 emails per 7 days and it's a struggle. This doesn't include the multiple operational emails we send. Personas and segmentation are coming into play. Marketing (growth/upsell) primarily focuses on C suite, VP and Directors. Engagement (customer comms/optimization) is focusing on ICs, Managers and Directors. It's not perfect but it works. We remove the newsletter from the limit so, if customers are suppressed from other emails due to the limits, then they are least get the info in the newsletter. We have also started segmenting newsletters to include some light growth content that's applicable to that audience. And we're quickly building out our community to use as a means of communication.
