Looking for better support of environments (production, testing etc) and more flexibility with emails (adding custom email headers as example). Should be a good fit not only for marketing emails but for things like app notifications and other auto-emails to users based on events.

We designed it from the ground to support a number of integrations  including emails, slack, clearbit and many others. We do support different env but not customizable headers.
