Ask HN: Weekly Employee Newsletter SaaS?

My wife needs to create a weekly staff company newsletter at, ideally displayed in an email. But open to other options - e.g if its a link to an interactive web experience.

I assumed this would be a super simple thing to do. I have looked at Mailchimp etc - but seem more geared towards mass email rather than sending out to employees. She needs to be careful around GDPR / data with uploading employees emails. She works in a pretty locked down IT environment, so that's another issue. Whatever solution will have to go via approval :(

I am looking for recommendations in the best way to do this either with a SaaS app or is there a good HTML email App for this? She is pretty tech capable - but not to write HTML / CSS for a day job :)

Thanks
