I work in Corporate Communications and one of the things my team wants to do send out internal email newsletters. Right now, everything is sent out using Outlook, which doesn't allow for responsive and well-designed emails. Their workaround is to have me code up the HTML emails, host them somewhere, and paste them into an Outlook email, which doesn't really work because most of the styling is ignored.
So, I'm wondering what kind of tool would work for this? I've used email marketing tools like Mailchimp but my concern with that is that we don't want employees to be able to unsubscribe from these emails. I'm sure other companies out there send out internal newsletters so what's some best practices for this? What tools are best for this?
