For a SaaS Analytics product it can make sense to  send periodic nice-looking emails showing headline summaries and tables. I am surprised at the lack of low-effort solutions for this, but maybe I am not doing the right google search. This world seems to have its own terminology, like transactional/marketing, etc. Hence this Ask HN.Key requirements:- look good on mobile (i.e. responsive)- dynamic content, i.e. templatized, with variables- need to include tabular data with say 5 rows and 3-4 columns- look good with nice designs- Unsubscribe option- Mostly doable in PythonWe are looking at SendGrid, but I am not impressed with how the emails turn out, especially with tabular data. Mailchimp could be an option, but haven't gone down that path.Thank you.
