@JOduMonT Thanks for the numbers! Elasticmail for 1.5M emails would be $135/month Standard and +$30 for Pro, so $165/month for comparison. Basically, $515 to $665/month cost-savings on the table, or $6,180 to $7,980 a year. The research kinda pays for itself a few times over once you get above say 10,000 emails a month. You do need to bring your own client though, like Mailtrain - but then it will support a hosted HTML page generated anywhere if the GUI templates aren't pleasing to the design team.
